TOP END KITS
Wiseco’s complete top end Piston Kits are offered for nearly every popular motorcycle application. These kits contain
everything you need to complete your rebuild the right way, the first time. High quality parts specifically chosen by us
to match our forged pistons are included in this kit for easy one stop shopping.
• 2-stroke kits feature our Pro-
Lite™ pistons that are CNC
machined for optimal cam
shape and profile for peak
HP and service life.
• Each piston is built from
race proven designs that
are chosen by the top race
teams in all forms of racing
including Supercross,
Motocross, GNCC,
Superbike, and more.
• 4-stroke kits feature a
‘race-ready’ dome finish
with smooth edges for

and noise to contribute to
increased horsepower.

superior strength to weight
ratio utilizing aerospace
alloy.
• High Performance ring kit
and alloy pin included with
each piston kit for extended
life and sustained power.
