TKRJ Yamaha RXK 135 Piston Kit 2.00 AY0758X

The Yamaha RX135 (RXK) is a 2-stroke powerhouse known for its raw acceleration and iconic exhaust note. When your cylinder has reached its limit or you're looking for a significant bore-up to restore compression, the TKRJ Piston Kit (2.00mm Oversize) is the professional choice. Manufactured in Japan, this kit provides the perfect balance of thermal stability and high-RPM durability for the ultimate top-end rebuild.

Why TKRJ is the Ultimate Choice for RX135 Enthusiasts:
Japanese Precision Engineering: TKRJ pistons are world-renowned for mirroring the exact metallurgical properties and weight of original Yamaha factory parts, ensuring a "factory-fresh" feel even at extreme oversizes.

2.00mm Maximum Oversize (8th OS): This kit is designed for cylinders that have seen years of action. It allows a machinist to clean up deep scoring or wear, extending the life of your original cylinder block while slightly increasing displacement for a punchier low-end.

Superior Heat Dissipation: Crafted from a high-silicon aluminium alloy, this piston is engineered to resist "four-point seizing" and maintain its structural integrity under the intense heat of a high-revving 2-stroke engine.

Precision-Matched Ring Set: Includes premium Japanese rings designed to seat quickly against the cast-iron sleeve, ensuring maximum compression, minimal blow-by, and a cleaner burn.

Optimized Port Geometry: The piston skirt and crown are precision-machined to ensure perfect timing with the RXK’s transfer and exhaust ports, maintaining that explosive power delivery the 135 is famous for.
