About the Yamaha YZ250WR
Keep the full WR model designation and the application of each fork or clutch part.
The featured YZ250WR service selection covers front brake pads, separate friction and steel clutch plates, fork dust seals and an oil-seal set. Four of those products list 1989–1990, while the oil seals name 1989 only. A common dust-seal or clutch application cannot establish a 1990 oil-seal fit.
Separate the two clutch plate types
The friction plate uses Yamaha reference 22U-16321-00; the plain steel plate uses 4X7-16325-00. Both are individual products. Keep the plate types and stack positions on the order, and compare the installed clutch before deciding counts. Retain YZ250WR in the enquiry when other Yamaha model names appear on the product title.

For 1990 fork oil seals, identify the fitted fork and seek a product that explicitly covers it. The 1989-only example is not a confirmed substitute.
Identify your motorcycle before orderingConfirm the YZ250WR before ordering
- Copy the full model designation and frame marking, retaining WR and the model year.
- Compare the exact YZ250WR line on each product instead of substituting a YZ250, WR250 or YZ250F entry.
- Identify the fitted fork, front caliper and clutch components. Check each seal’s coverage and each plate’s selling quantity.
