Hey motorcycle riders, is your front fork leaking oil or letting in dirt? This universal seal kit is probably what you need. It includes 2 oil seals and 2 dust seals that fit a 46mm inner diameter and 58mm outer diameter, with an 11mm thickness. They're made from durable nitrile rubber (NBR) to handle oil, weather, and road grime. This specific size is known to fit models like the Yamaha WR400F/YZ400F (98-00), WR426F/YZ426F (00-02), and the Kawasaki Ninja ZX9R (98-03), but please – and this is important – double-check the measurements of your old seals before you buy! Swapping out worn seals is a key part of fork maintenance that keeps your suspension working smoothly and prevents bigger problems down the road. This kit gives you everything you need for one fork leg in one package. A solid, affordable repair part for keeping your bike in top shape.
