The Wiseco 4366M10000 is a forged piston kit designed for the Honda XR600R, featuring a 100.00mm (3.937") bore diameter. Wiseco pistons are forged from high-silicon, low-expansion aluminum alloy, delivering superior strength, reduced reciprocating weight, improved heat transfer, and extended service life compared to OEM cast pistons.

Key Features:

• Forged aluminum construction — high-silicon, low-expansion alloy provides greater strength and durability than cast alternatives

• Compatible with all cylinder bore types — suitable for cast iron, chrome, Nikasil, and boron composite cylinder compositions
• Oversize availability — part of Wiseco's wide range of oversize options to restore worn cast iron lined cylinders to proper tolerances; chrome, Nikasil, and boron composite cylinders can be resleeved to accept Wiseco oversizes
• Complete kit — includes piston, rings, circlips, and wrist pin

Wiseco's state-of-the-art computerized manufacturing facility ensures every piston meets exacting tolerances, making this kit suitable for both high-performance racing applications and recreational riding. The 4366M10000 is a direct-fit solution for rebuilding or upgrading the Honda XR600R top end.
