More Power for Vespa Smallframe

The potential of Smallframe engines has been increasing during the past years and seems to increase even further.

Today you can find levels of performance and torque above 35HP / 30Nm more often. This, in turn, puts more sprain on other parts.

Springs for primary drive have to be stronger

Clutch and primary drive are crucial and highly strained links between crankshaft and drive. Its weakest part are the springs of the jolt damping.

These transmit the entire torque to the rear wheel, guarantee a symmetrical power transmission to the gearbox and smoothen the asymmetric flow of the crank drive between the dead centres. Not only in racing heavy crankshafts, lighter flywheels and immense load alterations shorten the tough life of the original springs.

New reinforced springs by BGM PRO

We added reinforced springs to our stock for you. These fit the BGM PRO repair kits BGM0190, BGM0192, MMW Hartz4/5 and they also fit the original primary drive repair kits.

The new BGM PRO springs provide more power

Comparing our springs to a Piaggio spring, you will see that the BGM spring is more elastic and the spring wire offers a larger deviation.

A larger possible deviation and a higher spring constant protect the primary drive of sharp breaking parts, even in toughest conditions.

Due to fitting conditions you cannot simply enlarge the spring to enhance its life span. Therefore we paid attention to use good material. Oteva is a highly robust spring steel, which is used for extremely dynamic loads. Its distinguishing characteristic is its durability in high temperatures during extreme mechanical use. Its surface is shot peened to further enhance durability.
