Description
Product Overview
The ZOZOYE Chrome Piston Kit is a direct‑fit replacement designed specifically for Honda CR85R motorcycles produced between 2003 and 2007. Crafted from high‑grade aluminum alloy and finished with a corrosion‑resistant chrome coating, the piston offers a balance of lightweight strength and heat dissipation. The kit includes a 47.5mm size B piston, matching piston rings, a precision‑machined piston pin, two retaining clips, and a complete gasket set, ensuring every critical sealing surface is addressed. With a net weight of just 6.9 ounces and compact package dimensions of 5.91 x 5.91 x 1.97 inches, the components are easy to handle during service. OEM references such as 13120-GBF-B40, 13120-GBF-B00, and several cross‑reference numbers guarantee compatibility with factory specifications, while the chrome exterior adds a subtle visual upgrade.
Usage
Designed for both seasoned mechanics and DIY enthusiasts, this piston kit fits seamlessly into routine engine rebuilds, performance upgrades, or emergency repairs. Ideal for track days, off‑road riding, or daily commuting, the kit restores original compression levels and promotes smoother power delivery. Install the piston during a standard top‑end overhaul: remove the old piston, clean the cylinder, install the new gasket, position the piston with the supplied rings, insert the pin and secure with the clips. The chrome finish not only resists wear but also simplifies visual inspection for wear patterns.

FAQ
Is this piston kit compatible with all CR85R model years?
The kit is engineered for Honda CR85R motorcycles produced from 2003 through 2007. It matches the OEM part numbers listed and fits the 47.5mm bore size used in those model years.
Do I need any special tools to install the piston?
Standard motorcycle engine tools are sufficient: a piston ring compressor, torque wrench, and basic hand tools. The included clips and pin are pre‑drilled to the correct dimensions, so no additional machining is required.
Can I use this kit for performance upgrades?
Yes. The lightweight chrome piston reduces reciprocating weight, which can improve throttle response. However, for extreme performance builds, consider pairing it with a high‑compression head or upgraded cylinder.
What warranty does ZOZOYE provide?
We offer a one‑year limited warranty covering manufacturing defects. If you encounter any issues related to material or workmanship, contact our support team for a replacement or refund.
How do I verify that the piston fits my engine before purchase?
Check the OEM part numbers listed in the product details against your bike’s service manual. If you are unsure, compare the existing piston’s markings with the numbers provided (e.g., 13120‑GBF‑B40). Our customer service can also assist with verification based on your VIN.
