Wiseco Piston Kit - 47.50 Mm For Honda Cr85R - High-Performance Forged Piston Assembly

The Wiseco 833M04750 piston kit is expertly engineered for enthusiasts and professional racers seeking maximum performance and durability for their Honda CR85R. Crafted from high-silicon aluminum alloy, this forged piston offers superior strength, ensuring reliable operation under demanding trail and racing conditions. Its innovative forging design and durable piston skirt deliver increased horsepower, enhanced torque, and extended service life, making it an excellent upgrade for competitive riding.

Designed with precision, the Wiseco 833M04750 features titanium nitride-coated rings, which contribute to higher compression ratios and improved sealing. The piston is fully E-coated on the crown, ring grooves, and pin bore, providing exceptional wear resistance and protection against micro-welding, galling, and detonation. This advanced coating enhances longevity and maintains optimal performance over extended use. The piston assembly includes rings, wrist pins, and circlips, assembled for ease of installation and reliable operation.

The GP Series piston is designed with less external machining, which helps seal the bore tightly, resulting in increased compression and a more predictable powerband. Boost ports are removed to deliver a more consistent pull on the top end, ideal for racing applications. Please note that cylinder sleeves are sold separately. These pistons are suited for expert racers and tuners aiming to push their Honda CR85R to the next level, with the potential for increased service intervals compared to conventional Wiseco pistons. Trust the Wiseco 833M04750 piston kit for a combination of high performance, durability, and race-ready reliability.
