caster angle motorcycle

[...] The axle of the fore-carriage is situated a suitable distance behind the projection of the axis of the pivot-pin in order to ensure the stability of direction above referred to. We use data about you for a number of purposes explained in the links below. The caster angle or castor angle is the angular displacement of the steering axis from the vertical axis of a steered wheel in a car, motorcycle, bicycle, other vehicle or a vessel, measured in the longitudinal direction.wikipedia It is the angle between the pivot line (in a car - an imaginary line that runs through the center of the upper ball joint to the center of the lower ball joint) and vertical. To have a clear visualisation you can consider the example of a motorcycle shown below. » BikesMedia.in The purpose of this is to provide a degree of self-centering for the steering - the wheel casters around so as to trail behind the axis of steering. There’s lots to digest when it comes to a motorcycle’s handling. © 2021 VerticalScope Inc. All rights reserved. Negative caster angles reduce the steering effort but create wheel wandering problems. Trail braking into a corner helps keep the fork compressed (and control the rate at which it rebounds) to maintain your intended arc. The caster angle or castor angle is the angular displacement of the steering axis from the vertical axis of a steered wheel in a car, motorcycle, bicycle, other vehicle or a vessel, measured in the longitudinal direction. The caster angle is the angular displacement of the steering axis from the vertical axis of a steered wheel in a car, motorcycle, bicycle measured in the longitudinal direction. Camber. ENGINE In the extreme case of the shopping trolley wheel, the system is undamped but stable, as the wheel oscillates around the 'correct' path. In the motorcycle industry, caster angle is synonymous with what would be called the head angle in the bicycle industry. A motorcycle's front wheel pivot angle is easily visualized. A very visual example of positive caster is a motorcycle's front steering forks. Caster. Caster is the angle which the vertical axis of the wheel makes with the steering axis. Higher Steering Axle Inclination (SAI) angles help in improving the steering wheel returnability and decreasing the steering effort as well. Think of caster as the fork rake angle of a bicycle or a motorcycle. Fuel Capacity 2.96 gal. Lets start with basics Caster – Negative and Positive Caster is the measure of how far forward or behind the steering axis is to the verticle axis, viewed from the side. 3. Some of the most important geometric consideration on a motorcycle are the . The rubber bushes wear, and their elastic qualities change as they grow old. An example of caster in action is the front wheels on a shopping cart. A positive caster angle is shown with the front of the vehicle being to the left. Raising or lowering the rear has a similar effect to raising or lowering the front, and again, there is a finite and limited amount you can raise or lower the rear, too – if you can at all. At this displacement, the 701 begins to compete with Adventure bikes. Think of caster as the fork rake angle of a bicycle or a motorcycle. The caster angle (26.7°) and short wheelbase contribute to quick handling, while the high rigidity of the frame ensures straight-line stability. To have a clear visualisation you can consider the example of a motorcycle shown below. Because of the caster angle, camber angle of front tire is higher than the rear tire which requires the front tire cross sectional profile to be more circular. Rake (Caster Angle): 26.4 deg. However, this isn’t always the case. A good starting point for this is 30 mm behind the nominal contact patch. A rake angle is the angle which can be calculated by drawing an imaginary perpendicular line from the front axle and a line drawn from the steering head of the bike. Wikipedia. Topics similar to or like Caster angle. We’ll start with the basics of rake and trail, then go a little deeper into each topic later. Power steering is usually necessary to overcome the jacking effect from the high caster angle. A positive caster angle is shown with the front of the vehicle being to the left. The caster can also be of three types. Swingarm length, chassis rigidity, fork spacing, and many other variables are also taken into consideration. Chopperssometimes have an extreme caster anglefor aesthetic reasons This distance is called the pneumatic trail and varies with speed, load, steer angle, surface, tire type, tire pressure and time. The rear suspension design can be any number of options. Trail: 2.5 in. However, something you can do is raise or lower your fork tubes in the triple clamps. Now that we’ve established quicker steering is achieved through steeper rake and/or shorter trail, and better stability is the result of more relaxed rake angles and/or longer trail numbers (and we have not even begun to discuss how wheelbase affects a motorcycle’s handling), what can you do to your motorcycle to change these numbers? The steering axis angle, also called caster angle or head angle, is the angle that the steering axis makes with the horizontal or vertical, depending on convention.The steering axis is the axis about which the steering mechanism (fork, handlebars, front wheel, etc.) Most of the time the two are parallel to each other. The caster angle or castor angle is the angular displacement of the steering axis from the vertical axis of a steered wheel in a car, motorcycle, bicycle, other vehicle or a vessel, measured in the longitudinal direction. 10. Like mentioned at the start of this piece, rake and trail are important aspects in determining how a motorcycle handles, but there are many more variables to take into consideration that go beyond the scope of this article. This can be a lot to process, but the important thing to remember is that we can take advantage of this dynamic rake to make the bike handle a certain way. It is the angle between the pivot line (in a car an imaginary line that runs through the center of the upper ball joint to the center of the lower ball joint) and vertical. It’s not often any of us get to ride on a banked oval, but the combination of high speed and banking naturally compresses both the fork and shock, altering geometry. It’s mentioned so much because rake and trail have a major role to play in the way your motorcycle handles, and the people who design these motorcycles are well aware of this when going from CAD drawing to real-life machine. 5 out of 5 stars (3) 3 product ratings - NEW Sealey Magnetic Wheel Hub Mounting Camber Castor King Pin Angle Gauge GA450. So, let’s take a closer look at what rake and trail is and why it’s important. ", https://www.cyclechaos.com/w/index.php?title=Caster_angle&oldid=47793. And besides, what harm is there in a refresher course, anyway? Rotating elements are disposed in the plates and enable same to rotate around the axle which is blocked in rotation by the guiding piece. Choppers sometimes have an extreme caster angle for aesthetic reasons. Raising the tubes within the clamps slightly reduces rake while lowering the tubes does the opposite. Most motorcycles don’t come with fancy concentric head stock inserts or adjustable triple clamps. Adjustable-Caster Angle Device for a Motorcycle . Conversely, as the motorcycle is accelerating the fork is extending, increasing the rake angle slightly. For ultimate tunability, concentric inserts and different triple clamps can be used together to dramatically alter a motorcycle’s handling. As you’ve likely seen on those wild biker build-off shows, some cruisers can have huge rake angles that are downright ridiculous. There is no caster setting for the rear of a vehicle. Known as the angle between the vertical access and the rotational access. Camber angle could be either positive or negative depending on the design of the chassis and suspension system. This makes a vehicle easier to drive with a better steering response and directional stability. The Husqvarna 701 is the largest single-cylinder motorcycle available. Wet Weight: 134 lb. Hard braking will nearly collapse the front end, temporarily creating a very shallow rake angle, making the bike steer quicker. MPG 78 mpg Dry Weight Curb Weight: 370 lb. Hopefully by now you can see how rake and trail are interconnected, as rake automatically has an effect on trail – less rake means less trail, and vice versa. Excessive caster angle will make the steering heavier and less responsive, although, in racing, large caster angles are used to improve camber gain in cornering. In this illustration of the Honda CB1000R we get a better understanding of trail, or the distance from an imaginary line drawn through the head stock to the ground and the front contact patch (which is usually, but not always, in line with the front axle). It doesn’t have to be big to be an Adventure. It is the angle between the pivot line (in a car an imaginary line that runs through the center of the upper ball joint to the center of the lower ball joint) and vertical. It’s called Pearl Deep Mud Grey, which frankly sounds like something you’d find in Willy Wonka’s Chocolate Factory. Steering. It is known as the kingpin inclination or the steering axis inclination. Join the Motorcycle.com Weekly Newsletter to keep up to date on all things motorcycling. Primary among these are wheelbase, steering axis angle, fork offset, and trail. 28 deg. To avoid confusion, BikeCAD does not use the term caster angle. This makes a car easier to drive and improves its directional stability (reducing its tendency to wander). Castor or Caster angle . By continuing to browse our site you agree to our use of data and cookies. Note also that, despite having the same wheelbase (1455mm), the CB1000R and CBR1000RR-R have different rake and trail numbers. Providing the desirable higher power output, but with the more manageable weight of an Enduro. For now, this should give you a base understanding to hopefully help you understand why your motorcycle handles the way it does. Rake (angle) redirects here. Read enough motorcycle reviews and you’ll inevitably hear people like the MO staff talk about two things: Rake and Trail. Positive Caster. Note how far the fork tubes are sticking out above the triple clamp. pivots. Rake is the angle of the bike’s steering head, sometimes referred to as caster. 2. The definition of rake (also known as caster angle) is the angle of the steering axis in relation to the vertical axis. At this displacement, the 701 begins to compete with Adventure bikes. It is calculated in degrees and measured as the angle between that of the steering head and the front axle if a line is drawn through the centre line of both – and followed vertically upwards in the case of the axle. On a MacPherson strut car the caster angle is the angle of the line from vertical drawn from the top strut mounting point through the lower ball joint to the ground. Sometimes in the bicycle industry, the term caster angle is used to describe the arctangent of the trail divided by the wheel radius. Arthur Krebs applied the first positive caster angle to automotive front-train in his 1896 car, English patent : "To ensure stability of direction by means of a special arrangement of fore-carriage, that is to say, to re-establish automatically the parallelism of the two axles of the vehicle when there is no tendency to keep them in any other direction, or after a temporary effort has caused them to diverge from said parallelism. These parameters have a major influence on how a bike handles. θ is the caster angle, red line is the pivot line, grey area is the tire. The tradeoff, of course, is a stable motorcycle once you do get it leaned over. Other. Some aftermarket companies also produce triple clamps that effectively achieve the same result. Take a line and draw it through the steering axis until it meets the ground. This is possible because the caster angle is actually 28 degrees and the trail length 4.3 inches, achieving both straight-line stability and neutral handling. The reverse is true of the tadpole. Providing the desirable higher power output, but with the more manageable weight of an Enduro. Basically, it is the angle which the wheels of a vehicle make with the vertical axis as seen from the front of the vehicle. The front steering forks on a motorcycle are an easy-to-see example of how caster works. The pivot points of the steering are angled such that a line drawn through them intersects the road surface slightly ahead of the contact point of the wheel. Caster Angle. Bicycle and motorcycle geometry is the collection of key measurements that define a particular bike configuration. For this, the king-pins (in rigid suspension) or ball-joints (in independent front suspension) slightly tilt from the vertical line. For cutting geometry, see Rake angle. With a 59.8-inch wheelbase and a 30-degree fork angle, the Rebel 1100 achieves a cruiser style that belies its sporting capabilities. Bike wheelbase, head angle, fork offset (AKA rake), and trail Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular… The steering axis angle usually matches the angle of the head tube.. Positive caster is when the top upright mounting point is more rearward of the car than the bottom mounting point when looking at the side view. This is possible because the caster angle is actually 28 degrees and the trail length 4.3 inches, achieving both straight-line stability and neutral handling. In other words, it is the angle between the pivot line and vertical. Lets start with basics Caster – Negative and Positive Caster is the measure of how far forward or behind the steering axis is to the verticle axis, viewed from the side. The camber angle is read one degree plus or minus 30 minutes. Caster is a stability angle, measured in degrees. Caster angle Last updated January 14, 2020 θ is the caster angle, the red line is the pivot line, and the grey area is the tire. This is a wheel that gets steered on a vehicle, such as a bicycle, car, or motorcycle. Of course, knowing the angle of the wedge still doesn't tell us the overall caster angle. The KLX300 features a box-and-tubular-section high-tensile steel perimeter frame that creates a slim, lightweight package, which offers maneuverability and excellent handling on- or off-road. The forks point forward at the bottom and slope backward at the top. Buells were notorious for having some extreme rake angles bordering close to the teens. Device includes plates which are connected by an axle that extends through a guiding piece and a ball joint element positioned at the ends of a column tube. (See figure 3:1) As we have already seen, a motorcycle’s trail measurement plays a crucial role in achieving chassis stability, and it is the caster angle (among others) that helps to determine trail. I seem to remember that my W-22 is this way too, though I won't know for certain until later today as I will be visiting the storage yard. The most extreme example of this is in racing. Unfortunately, for many of us, the short answer is: not much. 1. If the axis leans back so the top of the suspension of behind the center of the wheel, this is positive caster. A positive caster angle produces a self-centering action of steering, and gives a steering feedback for the driver in straight line. Also, adjusting the rake angle does not tend to move the centre of gravity positon of the bike. In other words, rake is a measurement – in degrees – from the headstock of your motorcycle to a vertical line drawn through the front axle of your motorcycle. This topic when specifically applied to bicycles and motorcycles is more commonly referred to as rake and trail. 0 min. It is the angle about which the steering pivots in relation to the front and rear of the car. Universal Magnetic Alignment Gauge Castor Camber Wheel Vehicle. Caster is the angle which the vertical axis of the wheel makes with the steering axis. The shopping trolley/cart setup has a great deal of trail, but no caster. An example of a chopper with a raked fork at an extreme caster angle.. Topic. Angular displacement of the steering axis from the vertical axis of a steered wheel in a car, motorcycle, bicycle, other vehicle or a vessel, measured in the longitudinal direction. Jan 5, 2006.

Offset is a look at two axes: the axis of the steering head and the axis of the fork tubes. 2021 Yamaha MT-10 – Totalmotorcycle.com Canada Specifications/Technical Details. Camber angle could be either positive or negative depending on the design of the chassis and suspension system. On most production motorcycles you can’t change the fork offset without going to some extreme measures, but certain high-end motorcycles allow you to rotate a concentric head stem insert, resulting in altered trail. Caster angle is similar to these topics: Steering, Camber angle, Steering wheel and more. “Head angle,” “caster angle” and “rake angle” are all the same measurement. This is positive caster in a car. However, unlike KPI, the effects are beneficial. If it leans forward, it’s negative caster. The angle is measured by the angular space between the vertical and the pivot line, which is the line that runs from the lower ball joint to the upper ball joint. King-pin/ball joints (along with caster) provide directional stability in vehicles. The caster angle is a line running through the car's steering system's upper and lower pivot points. In other words, rake is a measurement – in degrees –  from the headstock of your motorcycle to a vertical line drawn through the front axle of your motorcycle. Positive caster is what we need to provide added stability, reduce tendency to wander and improve self-centering. Caster angle affects the camber of the wheel during steering. This page was last edited on 27 November 2010, at 20:02. Now, draw another line perpendicular to the ground down through the front axle (or, more specifically, the front contact patch, as they’re not always the same point). staff talk about two things: Rake and Trail. The best choice is a ‘telescopic fork’ positioned with some degree of caster angle to ensure that the car drives straight when you let go of the wheel. You can also go the other direction – up to the point where the fork tube sits flush with the triple. On a MacPherson strut car the caster angle is the angle of the line from vertical drawn from the top strut mounting point through the lower ball joint to the ground.

The angle between the drawn line and vertical is the caster angle. How does Rake (Caster angle) and trail effect low speed maneuvers? Bicycle head angle Share. A motorcycle's front wheel pivot angle is easily visualized. At the end of a corner, naturally the instinct is to accelerate. The point where the steering axis touches the ground lies in front of the point of contact of the wheel with the ground. θ is the caster angle, red line is the pivot line, grey area is the tire. The motorcycle according to claim 9, wherein when the caster angle θ is 20°, a trail length (mm) obtained from an offset length (mm) and the caster angle θ is at least 100 mm. Because of the caster angle, camber angle of front tire is higher than the rear tire which requires the front tire cross sectional profile to be more circular. The angle between these two is called the rake or rake angle, and it has a crucial role in a bike’s handling characteristics. The caster in this vehicle is read four degrees plus or minus one half degrees (.5°). Fuel Capacity: 0.9 gal. The steering axis (the dotted line in the diagram above) does not have to pass through the center of the wheel, so the caster can be set independently of the mechanical trail, which is the distance between where the steering axis hits the ground, in side view, and the point directly below the axle. That explains one of the reasons why we have to let off the throttle to help place the motorcycle in the intended direction. Alternatively, some higher-end motorcycles have shocks or linkages that allow for rear ride height adjustment. It also causes a camber gain (less negative camber) when steering on the outer wheel and thus improves vehicle behavior in cornering. In this case, it’s 24º. This is a wheel that gets steered on a vehicle, such as a bicycle, car, or motorcycle. Of course, there is a very finite and limited amount you can perform either function. The caster can also be of three types. This is positive caster in a car. (Setup like a motorcycle).

Caster angle[1] or castor angle[2] is the angular displacement from the vertical axis of the suspension of a steered wheel in a car, bicycle or other vehicle, measured in the longitudinal direction. This self-centering effect is achieved by tilting the king-pin from the top. This drawing of the Honda CBR1000RR-R explains rake angle concisely (ignore the other measurements, for now), as the arc created from the head stock to an imaginary line perpendicular to the ground, passing through the front axle. Conversely, you might have experienced trouble finishing a corner, experiencing a feeling as if the bike wanted to run wide. Caster angle. (Caster Angle) Trail 110 mm (4.3 in.) Free postage. The arms are connected to the chassis by rubber bushes to absorb the forces generated during driving thereby keeping the wheel angles under control. Thanks, Tony. away 11. With casters, there is no bible when it comes to leads. 1. Not only does it look silly, it can take a lot of effort to steer. specific change of the wheel angles when loaded and when going round corners. Complicating this still further is that the lateral forces at the tire do not act at the center of the contact patch, but at a distance behind the nominal contact patch. The Honda Fury is an extreme example. Adding a bit of complication to this is the fact rake angles are not static; when a fork is compressed under braking, this is effectively changing the rake angle of the front end, making it steeper. The interaction between caster angle and trail is complex, but roughly speaking they both aid steering, caster tends to add damping, while trail adds 'feel', and returnability. 2014 yamaha v-star 1300 tourer. Caster angles over 10 degrees with radial tires are common. An example of caster in action is the front wheels on a shopping cart. Rake Angle/ Caster Angle Rake angle determines the ability of a motorcycle to steer, it directly affects the steering ability of a motorbike, how fast or slow the motorcycle can take turns will be depending upon the rake angle it bears. There are many great books on the topic of motorcycle steering geometry if you’re interested. PMD Products Camber Caster Gauge and Wheel Alignment Rack Rim Clamp Mount Tool for 11" to 25" Rims But if we accelerate too early, the fork extends as we’re already running wide, making it harder to turn. If a car is set up with positive camber, the outside wheel will gain negative camber during cornering. It sometimes helps to think of caster angles like the forks on the front wheel of a motorcycle. On this Öhlins TTX shock, the rear ride height is adjustable via the threaded collar at the bottom. There is a smaller angle (and therefore smaller lead) that is referred to as a “standard-lead,” but this can vary slightly from manufacturer to manufacturer. The angle between the king-pins or ball-joints center line and the vertical line forms Caster angle as seen from the side. Trail is what makes the front tire want to self-center and is usually what we’re referring to whenever we say a bike feels stable. Click & Collect.
