bgm PRO variator for Piaggio Quasar engines, e.g. Vespa GTS
- with extra long ratio range
- perfect traction and
- high rear wheel performance.
The bgm PRO variator uses a shorter and Kevlar-reinforced V-belt than is usual with Quasar engines. This allows our Vario to run a significantly wider range of ratios without the V-belt grazing the housing, as is the case with a Malossi Vario, for example. As a result, the bgm Vario can achieve significantly higher gear ratios without the engine having to rev higher. A huge advantage, especially if the engine is to be tuned further.
Engine power directly at the rear wheel
Countless test bench and road tests have shown that the 250/300cc Quasar engines do not require a harder or different counter-pressure spring than the standard one. The entire engine power is therefore not absorbed in frictional heat, but ends up where it belongs: on the rear wheel.
Vespa GTS Variomatic test
With the Piaggio standard variator, the engine runs into the limiter much earlier. In terms of the speed axis, the power is therefore maintained for much longer, which is noticeable in a higher top speed.
Compared to the Polini set, the bgm Vario does not operate at an artificially high speed level in order to achieve an aha effect. Unfortunately, the Polini Vario buys its (too) high speed level with a poorer efficiency.
By maintaining the same acceleration speed as the standard engine, our bgm Vario kit ensures that the engine is not overloaded and the power output is pleasantly linear. In everyday use, the superiority of the bgm Variomatic is clearly evident in a direct 1:1 comparison.
