MOTO-MASTER floating Front Oversize Brake Kit Ø270 mm for KAWASAKI KXF 250, KXF 450 2015-2026

The MOTO-MASTER Ø270 mm flottant avant 310021 oversize brake kit is designed for KAWASAKI KXF 250, KXF 450 from 2015 to 2026. An oversize kit replaces the stock disc with a larger-diameter disc, along with a bracket that relocates the caliper.

Good to know

The kit goes on in place of the stock disc, with the caliper bracket supplied. Check that the oversize disc clears your bike's wheel and fork (the compatibility list below tells you).

Fitting tips

1. Remove the wheel, the stock disc and the caliper, without opening the hydraulic system.
2. Fit the oversize disc on the hub, bolts tightened in a criss-cross pattern to torque, with medium-strength threadlocker.
3. Mount the caliper bracket on the fork leg, then the caliper on the bracket, to the manufacturer's torque.
4. Check that the disc is centred in the caliper and that the wheel spins freely, and fit new pads if the kit doesn't include any.
5. Bed the brakes in gradually before riding hard.

Why MOTO-MASTER?

In motocross, Moto-Master was working with the Red Bull KTM Factory Racing team as early as 2010, and it backed the MXGP world championship in 2015. On the technical side, the Flame profile of its discs is designed to improve cooling and go easy on the pads, and its Racing GP sintered pads use a backing plate with hooks (NRS technology) that stops the friction material from coming away.
