Upgrade kit for the primary reduction of all Vespa largeframe engines, e.g. Vespa Sprint, Rally, PX, Cosa, or T5 The kit has reinforced shock absorber springs. This means that the high torque of modern engine concepts is countered by a correspondingly increased spring rate. This means that the standard springs no longer go on block and thus prevent load change peaks from being transmitted to the clutch or the engine housing. This means that the lugs of the linings last much longer and the risk of the original springs breaking is eliminated.
Ideal supplement to the BGM Pro Superstrong clutch
strengthens the primary drive
protects the entire drive train, especially the clutch
Fits all primary transmission ratios of PX motors
Springs made in Germany
With a spring rate of 48N/mm, the springs are sufficient even for very high-torque motors and offer the perfect symbiosis of material protection and sufficient spring hardness
