Vertex Cast Replica Piston Kit 23614B — 1995-2013 Kawasaki KX100 / Suzuki RM100 (52.45mm)

Product Description

Refresh your 2-stroke top end with the Vertex Cast Replica Piston Kit (23614B). Specifically engineered for the 99cc Kawasaki KX100 and Suzuki RM100 engines, this gravity-cast aluminum alloy piston matches the exact factory specifications of your original equipment to provide clean, consistent compression and reliable power delivery.

Vertex cast pistons are constructed from an advanced aluminum alloy optimized with an 18% silicone content. This formula decreases thermal expansion, allows for tighter cylinder clearances, and significantly limits skirt wear. Finished with a high-tech Molybdenum Disulphite (MoS2) skirt coating, this kit guarantees quick break-in times and extended durability under harsh race conditions.

Frequently Asked Questions

Q: What is the significance of the "B" designation in this piston kit?
A: Piston sizing increments like "A", "B", or "C" provide precise fractions of a millimeter adjustments to match slight cylinder wear. The 23614B kit features a 52.45 mm diameter, which matches a standard 52.50 mm bore while offering optimal clearance for slightly broken-in cylinders.

Expert Pro-Tip: Always measure your cylinder bore with a dial bore gauge to determine the correct piston size step before ordering. During installation, make sure the ring end gaps are aligned according to the factory service manual and thoroughly coat the wrist pin and small-end bearing with high-quality 2-stroke oil.
