Motorcycle Frame & Chassis FAQ
What materials are used in motorcycle frames and chassis?
Motorcycle frames and chassis are typically made from materials like steel, aluminum, titanium, and sometimes carbon fiber, each offering different strengths, weights, and costs.
How does the chassis affect motorcycle performance?
The chassis influences the motorcycle's handling, stability, and ride comfort. A well-designed chassis can improve maneuverability and responsiveness, which are crucial for performance.
Is it possible to completely replace a motorcycle frame?
Yes, a frame can be completely replaced, but it requires significant work and must be done with a frame that matches the motorcycle's specifications or is approved by the manufacturer.
What does stretch refer to on a motorcycle frame?
Stretch refers to a change of the length of a motorcycle, from axle-to-axle. If you see a motorcycle frame or hardtail that says 3 inches stretch, for instance, that means that using that frame will add 3 inches distance between the front and rear axle of the motorcycle. This stretch is typically at the rear of the motorcycle, which means it would need a longer drive chain than the stock bike.
What does drop refer to on a motorcycle frame?
Drop refers to a change in the ground clearance of a motorcycle, which means the distance between the ground and the underside of the frame. If you are looking at a motorcycle frame or hardtail that is a 2 inches drop, that means the rear of the frame would be 2 inches lower than the stock configuration.
If you would like the frame to sit level with the ground, this means you would also need to shorten the front end 2 inches. This can be accomplished by using different length fork tubes or raking the neck of the frame. Some builders are looking for a different stance, but be sure to properly calculate the rake and trail of the motorcycle to ensure proper handling.
