Modern technology for oldtimer scooters. A solution which is not only adapted for Vespa scooters and which allows to adapt the old technology to the needs of nowadays road traffic.
In contrast with the charm of an old genuine steel rim (maybe even rusty), the new BGM wheel rim features many considerable advantages offered by the modern technology.
This robust wheel rim in aluminium allows you to mount tubeless tyres which are usually used in the motorcycle sector and replaces the geuine rim without any modifications necessary.
- 40% weight reduction
- More safety thanks to the double hump
- Improved responsiveness of the suspensions
- Good concentricity
In comparison with the Vespa PX genuine steel wheel rim, the BGM PRO rim is 600g lighter. Since you don’t need to mount a tube-type tyre, you’ll have about 370g less. The unsprung weight is reduced by almost 1kg for each axis (over 64%). Das Ansprechverhalten des Fahrwerkes verbessert sich spürbar.
Thanks to the double hump in the rim well the tyre always bonds to the rim safely. Like for the most recent runflat technology in automotive sector, if the tyre is punctured for instance by a nail, it loses air, but slowly and without sliding from the rim well. The tyre continues to support the vehicle’s weight and this allows you to keep control of the vehicle. The wheel rim also features cutouts between the mounting points. The cooling of the brake is improved.
The BGM PRO aluminium rim replaces one-to-one the genuine rim and fits almost all vintage scooters with manual gear change like e.g.
