The power and torque values that are now possible for so-called smallframe motors have increased significantly in recent years and seem to be growing steadily. Power and torque values of well over 35PS / 30Nm can be found more and more frequently. As a result, other components are of course also stressed significantly more. An important and highly stressed link between the crankshaft and the gearbox is the clutch and the primary drive. The weakest link in this chain are the springs for the shock absorption. 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 getting lighter and lighter and heavy load changes not only in racing, shorten the difficult life of the original springs. To match the BGM PRO primary repair kits BGM0195F48 and of course the original primary repair kits, we have added reinforced springs to our range for you. 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. The advantages of the BGM PRO spring (BGM0190F48) for primary Vespa Largeframe: increased travel, increased spring force ...
