About the Yamaha YZ250

Three YZ250 fork-seal size examples, with explicit later-year gaps.

Yamaha Motorcycle Logo

The YZ250 has a long service history, and the selected parts cover widely separated years. The carburetor kit lists 2000–2013 while the featured engine gasket set lists 1997–1998. The fork-seal examples below span early and later assemblies and should be compared using the motorcycle’s year and the fork actually installed.

Fork diameter and seal profile both matter

The selected pairs are 34 × 46 × 10.5 mm, 38 × 50 × 8/9.5 mm and 48 × 58 × 8.5/10 mm. Each contains two oil seals. The later pair lists 2004–2007 and 2010–2011, leaving 2008–2009 unconfirmed in this listing. A shared seal size or a nearby YZ250F application does not fill that gap.

Identify your motorcycle before orderingYZ250 model and component checklist

  1. Confirm the complete model designation and model year. Keep YZ250WR and YZ250F suffixes when present.
  2. Record the engine and carburetor markings before choosing internal engine or fuel-system service parts.
  3. Inspect fork and brake equipment for changes. Preserve application gaps instead of extending a range across an omitted year.

Yamaha YZ250 parts for common repairs

These selected parts retain their own year ranges, which may extend beyond your current filter. Check each product’s complete fitment and package contents before ordering.

Changing your YZ250 controls?

For handlebar and grip changes, measure the bar and control mounting areas and confirm cable reach and steering clearance. Choose a setup that suits the equipment fitted to your YZ.

Universal accessories require measurement and may need modification. A universal designation does not confirm YZ250 fitment.

Yamaha YZ250 parts questions

What fork-seal sizes are compared for the YZ250?
The selected pairs are 34 × 46 × 10.5 mm for 1974–1975, 38 × 50 × 8/9.5 mm for 1977–1980, and 48 × 58 × 8.5/10 mm for 2004–2007 and 2010–2011. Each supplies two oil seals; match the installed fork and complete seal profile.
Is the later YZ250 seal pair confirmed for 2008 and 2009?
Its current YZ250 application lists 2004–2007 and 2010–2011. It does not establish 2008–2009. Request confirmation using the fork identification and removed seal before ordering for either missing year.
Can I combine the YZ250 carb kit and gasket set using the same year range?
Check them separately. The selected carb kit lists 2000–2013; the engine gasket set lists 1997–1998. Ask for actual kit contents and any separately required seals, float parts or hardware for the repair.
Are the YZ250 brake pads linked here for the front wheel?
The featured listing specifies front pads for YZ250 1989–2005. Compare the installed front caliper and pad outline, and confirm how many pads and which retaining hardware are supplied. A model match does not by itself establish a complete brake-service package.
