Do you want the maximum amount of CC's out of your motor? Our 748 and 916 big bore kits are designed for ease of installation and maxium power.

One of the problems with going over 94mm bore size on the 748 or 916 engine is the cylinders. The problem lies in the cylinder wall thickness. You cannot bore out a stock 916 or 748 cylinder past 95mm because of the wall thickness. It will get too thin and eventually break while in use in your engine.

We have developed a cylinder that allows the use of 96mm bore size pistons therefore maxiumizing your power potential. Other companies have 96mm piston kits and cylinders which require you to totally dissassemble your engine cases and have them bored out to accept larger diameter cylinders which will cost you more for engine removal/rebuild and case machining.

Our kit requires none of this and can be installed with the engine still in the bike. The next great thing about our cylinders is that they are totally rebuildable for a lot less money than a stock cylinder.

Our cylinders have been in use now in high mileage street bikes as well as hard used race bikes. The results have been the same across the board for longevity, durability and performance.
