Manufacturer reference: MST439
TRW brake disc specially designed for Enduro and Supermoto practices. This round rotor with an outer diameter of 240 mm is machined from steel and offered with a bolt circle of 125.0 mm. Its design focuses on production with strict tolerances and precise surface grinding to limit vibrations and ensure good pad fitting over time.
Designed to withstand off-road and supermoto conditions, this disc offers an ultra-reinforced friction surface for better dimensional stability and increased durability. Its controlled machining limits surface irregularities for a more consistent lever feel and reduced vibrations felt at the lever and handlebars. Suitable for standard pad sets intended for this type of rotor.
