All of the torque is transferred to the rear wheel through them. They ensure uniform power transmission to the gearbox and dampen the uneven running of the crank mechanism between the dead centers. Heavy crankshafts, centrifugal masses that are becoming lighter and lighter and heavy load changes not only in racing, shorten the difficult life of the original springs.

New reinforced springs from bgm PRO

More power with the new bgm PRO springs

Compared to a Piaggio spring, the BGM spring offers more spring force and, thanks to the selection of the spring wire, more travel.



Due to the greater possible travel and the increased spring rate, the gearbox and primary drive are protected from tooth breaking load peaks even under harsh operating conditions.

Since you cannot simply increase the dimensions significantly to increase the durability, due to the installation conditions, we have paid attention to good material and workmanship for the spring. Oteva is an extremely resistant spring steel that is used for high dynamic loads and is characterized, among other things, by its durability even under the influence of high temperatures with simultaneous high mechanical stress. To further increase the durability of the spring, the surface is shot-peened.
