Moto-Master flame discs are lighter than most standard, so less unsprung weight. It's special flame design cleans the whole contact surface of the pads without tilting of the pads. This cleaning action is especially important when riding in muddy conditions. Flame design also ensures better cooling, which prevents fading on long downhills. The disc is made out of a zinc coated special chrome-molybdenium alloy providing the highest friction level on the market. This gives more stopping power and optimal wear resistance. All discs are laser cut, special heat treated and prescision grinded for perfect fit, superior strength and perfect feel.
