Vespa GTS with Malossi tuning on test bench

Vespa GTS on the test bench with Malossi tuning

Bernd's (customer) Vespa GTS has undergone some tuning measures, both visually and technically:

Engine: Vespa GTS with Malossi tuning

Everything from Malossi was fitted to the engine, from the cylinder and cylinder head to the clutch, variator and gearbox. As a result, the GTS has real pressure from below, the power increase is available across the entire rev range, and thanks to the Malossi Forcemaster2, the rev limiter is raised by 1,000 rpm, measured at 10,500 rpm on this vehicle. The 4 different setting maps of the Malossi Forcemaster2, depending on the expansion stage, also have the option of changing the injection quantity +-20% at min/medium/max.
