This is an EBC stainless steel rear brake disc – part number MD6234D – specifically designed for the 2006 Yamaha XT660X Supermotard.
It's brand new, never used, and it's a premium aftermarket replacement for your factory rotor.

It's made from high-quality stainless steel, which resists rust and corrosion better than standard steel, and it provides consistent braking performance even in wet conditions.
EBC is a top-tier brand in the motorcycle braking world, and this disc is no exception – it's built to last and designed to work with both organic and sintered brake pads.
The manufacturer part number is MD6234D, and the EAN is 5050953307263 if you need to reference it.

This is a rear placement disc, perfect for the XT660X, which is a popular dual sport and supermotard bike.
The fitment is specific – not universal – so you know it's going to bolt right up.

Installation is straightforward – just remove your old disc, clean the hub, and bolt this one on with the correct torque specs.
