ProX Piston Kit for TM EN300 and MX300 (01.7302.A)

The PROX 01.7302.A Piston Kit is designed as an OEM replacement for select TM EN300 and MX300 applications. Manufactured in Japan, this piston kit is engineered for dependable fitment, consistent performance, and long-term durability in demanding motorcycle environments. Its precision-focused construction makes it a practical choice for rebuilding the top end of a compatible two-stroke engine.
The piston is cast from a high-silicon-content aluminum alloy that meets or exceeds OEM specifications. This material helps provide strength, dimensional stability, and reliable operation under the heat and vibration associated with performance riding. After casting, the piston is CNC-machined to extremely close tolerances to support accurate fitment and smooth engine function when installed with the appropriate components and specifications.
The PROX 01.7302.A kit includes the essential components for a piston replacement, including the piston, ring kit, wrist pin, and circlips. Supplying these matched components in one package helps simplify the rebuild process and supports proper top-end assembly. Verify engine model, year, and application details before installation to ensure compatibility with your TM motorcycle.
