Malossi Super T Max quickens its steps. Mhr Power Transmission, art. 6714757, is a Malossi project: HTQ Z 26/40 pinion and ring gear pair with lengthened gear ratio, Malossi Morse lightened, narrower, frictionless racing chain. This system completely replaces the original primary gears (25-tooth pinion and 41-tooth ring gear) with a 26-tooth drive pinion and a 40-tooth driven ring gear, thus providing a 7% longer ratio. Besides providing this longer ratio, these gears are narrower, as to fit the new Malossi Morse racing chain, which is frictionless and without friction springs, thus lighter, more sliding and with higher resistance and long life compared to the original one, since "you can't break what is missing". Compatible with: - Yamaha: T-MAX 500 -03_S, T-MAX 500 04-07_S, T-MAX 500 08-11_S
