Custom Motorcycle Parts FAQ
What is most important when building a custom motorcycle?
The key to building a custom motorcycle is to decide on how you will be using it (around town, cross-country trips, weekend camping, racing) and how you want it to look. Having a goal will make it easier to decide which parts you need for your build. Check our How to Build a Bobber article for more info on a custom build.
How to make my motorcycle faster?
Horsepower will make your motorcycle faster. This is often achieved by using a free-flowing air filter and exhaust system that is properly tuned. Other methods include increasing the engine displacement (with a big bore kit) and other engine modifications (custom camshafts, cylinder head work, etc).
What changes should I do to make my motorcycle more comfortable?
Setting up your motorcycle for riding comfort is time well spent. Pay particular attention to the style of seat, footpeg location and handlebars. Handlebar height (rise) and pullback (how far the handlebars come back toward the rider) are very important for comfort as well as handling of your motorcycle. A high quality seat is worth every penny on that long road trip!
