Motorcycle Big Bore Kits

Unleash the power in your motorcycle by installing a big bore kit that lets the tamed beast free throughout the entire rev range. The unmatched performance delivered by a big bore kit increases horse power and typically change the power band characteristics to more of a low end power versus top end speed.

Motorcycle big bore kits generally include a cylinder, piston, ring(s), pin, clips and a top-end big bore gasket kit though you can also 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.

MotoSport delivers all motorcycle big bore kits fast and orders more than $79 ship free!.
