Wiseco Pro-Lite Top End Rebuild Piston Kit PK1908 - Kawasaki KX100 / KX112 2014-2025

Product Description

The Wiseco PK1908 Pro-Lite Top End Rebuild Kit provides a full top-end overhaul package engineered for high-rpm performance two-stroke engines. Designed specifically for the Kawasaki KX100 and KX112 platforms, this comprehensive setup replaces worn top-end components with dedicated forged racing units. Upgrading to the Wiseco PK1908 piston kit restores cylinder compression and engine output during essential top-end maintenance intervals.

Forged from 4032 aluminum alloy, the Pro-Lite piston features exceptional tensile strength and low thermal expansion properties required for competitive off-road conditions. Available in 52.50 STD Bore, 53.00 / +0.50, and 54.50 Big Bore size options, this kit accommodates standard bore setups as well as overbore cylinder builds. Each complete package includes a forged piston, dedicated ring set, wrist pin, circlips, wrist pin bearing, and a complete top-end gasket set to seal your engine cylinder correctly.

Frequently Asked Questions

Q: What size options are available for this Wiseco PK1908 kit?
A: This kit is available in three size options: 52.50 STD Bore, 53.00 / +0.50, and 54.50 Big Bore.

Q: Can I use OEM rings with the Wiseco piston included in this kit?
A: No, Wiseco pistons are designed to be fitted strictly with Wiseco replacement rings.

Q: Are Wiseco ring types interchangeable with each other?
A: No, Wiseco ring types are not interchangeable across different designations (such as CD or LC profiles).

Expert Pro-Tip: Before installing your new piston assembly, always measure ring end-gap inside the freshly cleaned cylinder bore using a feeler gauge. When installing the wrist pin circlips, ensure the clip open gap faces directly down (the 6 o'clock position) or directly up (the 12 o'clock position)—never place the circlip opening over the removal notch, as rotational inertia at high RPM can compress the clip and cause engine failure.
