Big Bore Kits

Unleash the power in your motorcycle by installing a big bore kit that frees the tamed beast throughout the entire rev range. The unmatched performance delivered by a big bore kit not only increases horsepower abut also generally changes the power band characteristics to more of a low end power versus top end speed. When buying a big bore kit for your motorcycle, you typically get a cylinder, piston, ring(s), pin, clips and a top-end big bore gasket kit. If necessary, you can buy certain parts individually to replace those already on your ride. If you need help finding the right big bore for your motorcycle or want some advice, call a gearhead at 503-783-5645 and get answers to your questions so you get the parts needed to make an informed buying purchase.
