What are motorcycle frames and hardtails made of?
Our hardtails and frames are made of DOM tubing, which stands for 'drawn over mandrel'. This ensures a consistent outside and inside diameter, and thus, wall thickness. This is high-quality tubing that does not have a weld seam in it, as we want our frames to be as durable as possible.
Traditionally motorcycle frames are made out of mild steel, though more modern motorcycles have frames made out of tubular aluminum as well.
Often, late-model motorcycles with aluminum frames use the engine as a stressed member, that is, the engine acts as part of the structure of the chassis. This type of design was patented way back in 1900, and utilized by makes such as Vincent, as well as modern super bike manufacturers.

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.

My bike leans too far/ not far enough on the kickstand, what can I do?
If your motorcycle leans too far over, or not far enough, when on the kickstand, making it unstable, you may need to change the length of your kickstand.
A bike that leans too far over needs a longer kickstand, and a bike that is too upright (making it unstead and liable to fall over) needs a shorter kickstand. One option for a shorter kickstand are stock-style kickstands that are 1 inches under stock length.
You can also use a universal weld-on kickstand to properly set the angle your motorcycle will sit at when on the sidestand. To learn more check out our informative, illustrated How-To DIY Universal Kickstand Install article!
