The 22mm Offset is recommended for the RM125/250. This offset is within 0.5mm of the original offset. Made from 2024 aluminimum, these clamps are stronger and lighter than stock (saves 4-7.5 oz), they help reduce stiction in your forks from uneven clamping by the stock castings and new split design allows for a lower torque spec. Bottom clamp has radiused corners for more flex similar to Suzuki's factory clamps. Comes complete with stem and lower bearing for an easy installation (stock offset 24 or 22.5 depending on year). For RM125/250 owners you will need to purchase a fine thread stem nut: PN: YZ-SN000-BA. Comes with 8 pinch bolts.
