Athena 05-09 Derbi GPR 125cc Standard Bore Cylinder Kit (w/56mm 125cc Modular Head)

If you're rebuilding the top end of your 05-09 Derbi GPR 125cc, this standard bore cylinder kit from Athena is a solid choice to get your engine running like new again. Athena has developed this kit to match the original performance and reliability you expect from your bike, ensuring smooth operation and dependable power delivery.

This kit features a lightweight aluminum cylinder with a nickel-silicon barrel coating. This coating is known for its durability and helps reduce friction, which contributes to better engine smoothness and longevity. The included piston is specifically designed to further minimize friction, meaning more of your engine's power makes it to the rear wheel. The modular head design with a 56mm bore is also part of this kit, ensuring a complete and integrated solution for your engine's cylinder assembly.

When you open the box, you'll find everything you need for a complete cylinder replacement: the high-quality aluminum cylinder, a complete piston assembly with pin and rings, and all the necessary gaskets to seal everything up properly. This comprehensive package makes the installation process more straightforward, as you won't need to source individual components separately. Just remember that this kit is not CARB approved and cannot be shipped to California.
