Designed for demanding transmissions, the PBR Standard Steel Sprocket 2309 - 525 is aimed at riders looking for a reliable and durable chain component. Made from 18NCD5 steel alloy, this standard sprocket incorporates PBR's competition expertise to ensure controlled wear and mechanical performance suitable for demanding roadsters.
The manufacturing process follows strict guidelines to limit corrosion and abrasion of the teeth, while optimizing the contact surfaces to reduce friction with the chain. It is a solid option to renew your primary transmission without altering the original ratio.
Compatibility (examples): suitable for models listed by PBR, including certain SUZUKI GSX-R 1000 (2020‑2021). Before installation, check the reference and chain pitch of your motorcycle to ensure a perfect fit with your sprocket and chain.
