The Namura NX-40111-6 piston kit is a high-quality upgrade solution for the Yamaha DT125R, DT125X, and DT125RE motorcycles manufactured between 1996 and 2006. This piston kit, specifically designed for the 57.5mm bore size, is an excellent choice for racers and enthusiasts looking to enhance their engine's performance.
The NX-40111-6 piston kit comes with six fully-forged pistons and piston rings, ensuring superior strength and durability compared to its casting counterparts. The piston's high compression ratio design improves combustion efficiency, allowing for increased horsepower and torque, resulting in better overall engine performance.
Each piston features a Guidotech coating that provides excellent heat dissipation. This coating, combined with the piston's lightweight design, ensures optimal engine cooling and helps prevent piston overheating, which is crucial for pushing the limits in high-performance applications.
The piston rings in this kit include:1. Compressive ring
2. Oil control ring
3. Oil scraper ring
These rings provide excellent sealing performance and help minimize oil consumption. The oil scraper ring, in particular, efficiently wipes the oil from the piston's underside and prevents oil from flowing into the crankcase, increasing engine efficiency.
The kit includes a complete set of piston pins and clips to ensure a hassle-free installation process. Additionally, the kit's piston design incorporates a use of premium materials to guarantee a long lifespan, even under the most demanding riding conditions.
In summary, the Namura NX-40111-6 piston kit is an ideal choice for Yamaha DT125R, DT125X, and DT125RE owners seeking improved engine performance and durability. This professionally engineered and manufactured piston kit is a must-have upgrade for aggressive riders, enthusiasts, and racers who want to take their motorcycle's power output to the next level.
