Wiseco 7853M10100 Piston Kit Standard Bore 101.00mm 12:1 Compression KTM 620 LC4

The Wiseco 7853M10100 is a high-performance forged piston kit designed for the KTM 620 LC4 engine with a standard 101.00mm bore and 12:1 compression ratio. Engineered and machined in the USA, this piston kit is built to the tightest tolerances for an optimal combination of power output and long-term durability.

Key Features:

• High-Silicon Aluminum Alloy Forging: Forged construction delivers superior tensile strength and dependability over cast alternatives
• ArmorGlide Skirt Coating: Reduces friction against cylinder walls for improved efficiency and extended service life
• Optimized Strength-to-Weight Ratio: Dedicated forging design minimizes reciprocating mass for faster throttle response and maximum torque
• Standard Bore: 101.00mm diameter — no cylinder machining required for standard replacement
• 12:1 Compression Ratio: High-compression design for increased power output in performance applications
• Complete Kit: Includes forged piston, piston rings, wrist pin, and circlips — everything needed for a top-end rebuild

Kit Includes: Piston, rings, wrist pin, and circlips (unless otherwise noted). Note: Oversize pistons require cylinder sleeving — verify bore size before ordering.

Wiseco piston kits are trusted at every level of off-road and powersports competition. Each kit is engineered for a specific engine application and manufactured to exacting standards in Mentor, OH, USA.
