This dossier records 5UN-25854-00-00 as a genuine OE number. Check the sources below for the applicable market and version.

Current evidence points to Yamaha WR250FA (WR250F) 1HC1 2011, Yamaha WR250FB (WR250F) 1HC5 2012, Yamaha WR250FD (WR250F) 1HC9 2013. Verify the year, market and engine version against the original vehicle information and source evidence.

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.
