Big Bore Kits

450s are fun because they have piles of power and you can rev the guts out of them. 500s are also a hoot. Big low end grunt allows you both power and finesse. No matter what you ride, you can get more of a good thing when you big bore your bike.

Our experience with this kit has been nothing short of amazing! The extra grunt this big bore offers will frequently allow you to pull a taller gear. This is great when you want to go faster, have more track speed, or simply be able to ride with greater control in the mid-range of the engine’s RPM.
