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
