Variator Vespa GTS bgm PRO Vespa Piaggio 250-300 cc Quasar engines
bgm PRO variator for Piaggio Quasar engines, e.g. Vespa GTS with an extra long gear range, perfect pulling power and high rear wheel performance. The bgm PRO variator uses a shorter V-belt reinforced with Kevlar than is usual with Quasar engines. In this way, our Vario can drive a significantly wider range of ratios without the V-belt, as is the case with a Malossi-Vario, for example.
