Wiseco CK210 Motorcycle Top End Piston Kit - 84.0mm 4-Stroke

The Wiseco CK210 is a forged 84.0mm top end piston kit engineered for high-performance 4-stroke motorcycle applications. Built from aerospace-grade aluminum alloy, each piston features a dedicated forging—not a generic casting—delivering a superior strength-to-weight ratio that cast pistons simply cannot match.

The dome geometry is precision-designed to promote improved flame travel for more efficient combustion, while the carefully profiled skirt shape ensures stability and smooth operation throughout the cylinder bore. Wiseco engineers each piston with exact installed clearances calculated to maximize power output, minimize wear, and achieve an optimal seal at full operating temperature.

Key Features:

• Forged aerospace alloy construction — tougher and more durable than cast pistons
• 84.0mm bore diameter — flat top conversion design for increased displacement
• Total displacement: 1441cc
• Optimized dome profile for improved flame travel and combustion efficiency
• Precision skirt profile for stability and reduced friction in the bore
• Engineered installed clearances to produce maximum power and best seal at running temperature
• Designed to withstand the demands of high-performance motorsport use

Wiseco's forged pistons are the preferred choice for performance riders who demand reliability under hard use. The CK210 kit includes everything needed for a top end refresh, making it a straightforward upgrade for riders looking to restore or enhance engine performance.
