Specifically suited for the motocross environment, this kit is aimed at machines requiring a 520 pitch and a quick response to acceleration. It is notably compatible with the HONDA CR 250 R (ME03) series from 1999 to 2001. Standard mounting, regular maintenance recommended (cleaning and lubricating the XS-Ring seals) to preserve performance and longevity of the entire setup.
Whether you are preparing the bike for off-road sessions or replacing a worn transmission, this JT/PBR kit focuses on the reliability of the components and the lightweight nature of the sprocket to maintain performance on jumps and during corner exits.
