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
