Features

KAYABA Dust Seal - 16x31x11 (Manufacturer Ref: 120301600201)

Designed for the motocross world, this KYB dust seal protects the shock absorber shaft from mud, sand, and debris during off-road outings. A compact and precise replacement part, it fits on shafts with a diameter of 16 mm and nests into a housing of 31 mm diameter for a useful height of 11 mm — ideal for maintaining sealing and limiting wear on the seals around the shock absorber body.

Inner diameter: ø 16 mm
Outer diameter: ø 31 mm
Height: 11 mm
Brand: KAYABA (KYB)
Category: SPI Kit and Dust Seal

A simple yet essential part for riders who engage in off-road sessions: it limits the intrusion of particles on the shaft and around the oil seal, thus contributing to the proper functioning of the shock absorber. Compatible with many standard motocross forks and shock absorbers — check the diameter and height before installation.

Examples of commonly equipped motorcycles:

YAMAHA YZ 450 F (2026)
TRIUMPH TF 450-X (2026)
FANTIC XXF 450 (2026)
