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 translation range
perfect draft and
high rear wheel performance.

The bgm PRO Variomatik uses a shorter V-belt reinforced with Kevlar than is usual for Quasar engines. So our Vario can do a significantly wider translation bandwidth drive without such as with a Malossi Vario, the V-belt can touch the housing. As a result, the bgm Vario translate clearly furtherwithout the engine having to rev up. A huge advantage, especially when the engine needs to be tuned further.

Engine power directly on the rear wheel

The countless dyno and road tests have shown that the 250 / 300ccm Quasar engines do not need any harder or different counter pressure springs than the standard ones. The entire engine power is not dissipated in frictional heat but ends up where it belongs: on the rear wheel.

Vespa GTS variomatic test

With the Piaggio series variator, the engine runs into the limiter much earlier. In terms of the speed axis, the power is maintained significantly longer, which is noticeable in a higher top speed.

Compared to the Polini set, the bgm Vario does not work at an artificially increased speed level to catch an aha effect. The Polini Vario unfortunately buys its (too) high speed level with a poorer efficiency.

Maintaining the same acceleration speed as with the series engine means that our bgm Vario-Kit means that the engine is not subjected to higher loads and that the power output is pleasantly linear. In everyday life, the superiority of the bgm variator can be clearly seen in a direct 1: 1 comparison.
