Malossi HTQ Primary Gearbox z=13/43 – longer transmission for Peugeot Speedfight 3 & Looxor TSDI 50

If you have modified your scooter or are running a tuning cylinder, significantly more power reaches the engine – and this is exactly what can be converted into higher top speed. The problem: The original final drive ratio is usually designed so that the stock engine can pull it without problems. However, as soon as more horsepower is available, the engine quickly "revs out" at higher speeds: the RPMs increase sharply, but the top speed only improves minimally.

With the Malossi HTQ Primary Gearbox (z=13/43), you can adjust the gear ratio meaningfully. The gears and intermediate shafts are not only first-class in workmanship, they also bring the final RPMs to a tolerable level and allow the top speed to increase significantly – ideal if your Peugeot Speedfight 3 50 or Peugeot Looxor 50 TSDI is running with increased performance.

And don't worry about the usual myths: a longer transmission does not automatically mean that the scooter accelerates worse from a standstill. Often, minimally stiffer clutch springs are enough to compensate for this. On the contrary: if the gearbox is too short for the available horsepower, you are even wasting valuable power – the engine could "pull" significantly more.
