YZF-R7 High-Compression Piston Kit

Description

The Yamaha R7 High-Compression Piston Kit is a meticulously engineered upgrade designed to unlock the full potential of your motorcycle’s engine. Manufactured by CP Pistons according to VHM specifications, this kit is a testament to precision engineering and high-performance design. Suitable for Yamaha models from 2015 to 2024, this comprehensive kit elevates engine efficiency and power.

Each piston in the kit boasts a bore of 3.1496” (80mm) and is meticulously balanced to a precise weight of 218 grams, with a variance of only +/- 1 gram between pistons, ensuring smooth and balanced engine operation. The high compression ratio of 12.75:1 is optimized for significant improvements in power and response over the stock setup.

Crafted from the high-strength 2618 aluminum alloy, known for its exceptional durability and resistance to high temperatures and pressures, this piston kit is built to withstand the demands of high-performance applications. Features such as dual forced pin oilers enhance lubrication, while contact reduction grooves, an accumulator groove, and forged side relief are engineered to reduce friction and improve overall engine efficiency. The pistons are secured with high-strength chromoly wrist pins, locked into place with wire locks for added reliability.

The FEA (Finite Element Analysis) designed forging process ensures that each piston has the strength to endure the rigors of increased power output, while also optimizing the piston’s weight for performance efficiency.

This kit includes two pistons, two wristpins, two sets of rings, and four circlips, providing everything needed for a complete engine upgrade. Whether you’re aiming for competitive racing performance or simply wish to enhance your riding experience, the Yamaha R7/FZ-07/MT-07 High-Compression Piston Kit offers a perfect blend of durability, performance, and precision engineering, making it an essential upgrade for enthusiasts seeking the best from their motorcycle.
