Vespa GTS with Malossi tuning on

We have tuned up the Vespa GTS of our customer Bernd not only with a facelift but also with a significative performance improvement:

Engine: Vespa GTS with Malossi tuning

The engine was tuned up with the Malossi cylinder, cylinder head, variator and gears. The Vespa GTS has now a higher torque at low revs and torque improved through the entire RPM band. Thanks to the Malossi Forcemaster2 the maximum number of revs measured for this Vespa is now 10,500 rpm, that is 1,000 rpm more than without this CDI.

Thanks to the 4 different maps of the Malossi Forecemaster2 you can change the fuel injection quantity ±20% at min/medium/max, depending on the tuning measures.

  • Curve 0: genuine cylinder, genuine camshaft, genuine cylinder head and Malossi exhaust with dB killer
  • Curve 1: genuine cylinder, genuine camshaft, Malossi cylinder head and Malossi exhaust with dB killer
  • Curve 2: Malossi cylinder, genuine camshaft, Malossi cylinder head and genuine exhaust
  • Curve 3: Malossi cylinder, genuine camshaft, Malossi cylinder head and Malossi exhaust with dB killer
