TOP END KITS
Wiseco’s complete top end Piston Kits are offered for nearly every popular motorcycle application. These kits contain every-
thing 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
improved combustion flow.
Horizontal slot-pin oiling
reduces friction and provides
scuff resistance, along with
a pressure seal groove for
maximum ring seal.
• PK kits from Wiseco feature
a complete top end gasket
kit that gives you everything
you need to complete
your rebuild from premium
materials.
• 4-stroke race applications
feature Wiseco’s
ArmorGlide™ skirt coating
to provide reduced friction
and noise to contribute to
increased horsepower.
• Dedicated forgings used for
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.
Top End kit includes: piston,
rings, wrist pin, clips, top end
bearing (2 strokes), and gasket kit
