Hayabusa 3mm Piston Kit
99-07 Hayabusa 1397cc
08-09 Hayabusa 1441cc
This is a 1397cc / 1441cc engine package which uses 3mm JE pistons. Kit includes a 3mm bored cylinder ready for exchange. You can also purchase the 2008 cylinder, which is redesigned with better windage to free up more horsepower, as an option for the 99-07.
RC's Performance also offers our Custom JE Slipper Pistons, which are lighter than the standard JE pistons, for those looking for every advantage. Less piston weight means that there is less rotating mass and less stress on your bearings.
The 2008 Hayabusa cylinder option is an extra $699.95 and is sold outright with No Core required.
In the picture above the 08 Hayabusa cylinder is in the front and the 99-07 cylinder is in the rear.
Kit comes with a 3mm bored cylinder (core required), 3mm JE pistons, rings, and wrist pins.
We need your cylinder as a core unless using the Outright option.
