Moto-Master Flame Supermoto Racing Front Brake Kit

For a great supermoto brake kit that offers all you need to get on track and go racing, Moto-Master's Flame Supermoto Racing Kit is the ticket!

Fits select 2023+ Yamaha YZ 250F-450F competition models! (Details below)

• A properly matched master cylinder and caliper kit offer great stopping power with really good feel that you can easily modulate.
• The 12mm master cylinder comes in two options - The standard RMC with a forged lever, as well as the CNC-machined all billet RMC-R.
• The supermoto-specific caliper features 4x 27mm pistons and was designed with spoked wheels in mind, so it offers great clearance.
• At 5mm thick, the Supermoto Flame Rotor is designed to withstand the abuse of high heat from supermoto riding at the track, in the canyons, and in the stunt lot.
• To suit your front wheel size, you can choose from 300mm and 320mm diameters. Rotor size affects caliper removal during wheel change, as well as the clearance between the caliper and spokes. Read more below to pick your rotor size!

Front wheel and rotor sizes go hand in hand! Here's how to decide rotor size:

• For smaller 16" or 16.5" front wheels on track bikes, the smaller 300mm rotor size is much better suited for easier wheel changes. The 320mm can be used here, but will require pad removal as well as loosening the rotor bolts before you can remove the caliper! Stick with a 300mm in this case to save yourself the headache.
• For the 17" front wheel more commonly used on the street, you'll need to stick with the 320mm rotor to avoid caliper and spoke interference!
