17D-25448-50-00 SPROCKET, DRIVEN (48T)

This dossier records 17D-25448-50-00 as a genuine OE number. Verify the applicable market and version.

Current evidence points to Yamaha YZ125F2 (YZ125) 1SRD 2015, Yamaha YZ125TL (YZ125) D689 2026, Yamaha YZ125TSE (YZ125 70TH ANNIVERSARY) D68D 2026. Verify the year, market and engine version against the original vehicle information.

Check the part number, model year, sales market, engine version, installation position and critical dimensions. The core parameters are recorded, but compare the physical old part before installation.

There is currently no evidence-confirmed genuine replacement relationship, so direct replacement cannot be concluded.

The same model may use different numbers and specifications across years, markets, engines or trim versions; verify the complete vehicle environment.

The current parameter template has values for every field. More images, exploded diagrams and cross-brand relationships can still be added.
