Primary gear repair kit -BGM PRO 12 springs (reinforced+)- Vespa Largeframe PX80, PX125, PX150, PX200, Cosa, T5 125cc, Sprint, GS160/GS4, SS180, VNC (since 11001), GT125, GTR125, TS125, GL150, VBC

Upgrade kit for the primary reduction of all Vespa large frame engines, e.g. Vespa Sprint, Rally, PX, Cosa, or T5. The set has reinforced shock absorber springs. This counteracts the high torque of modern engine concepts with a correspondingly higher spring rate. This means that the standard spring no longer goes onto the block and prevents load change peaks from being transferred to the clutch or the engine case. Thus the lugs of the pads last much longer and the danger of a breakage of the original springs is eliminated.

• Ideal supplement to the BGM Pro Superstrong clutch
• Increases the primary drive
• Protects the entire drive train, Especially the clutch
• Suitable for all primary ratios of PX engines
• Springs made in Germany

The springs with a spring rate of 48N/mm are also sufficient for very high-torque engines and offer the perfect symbiosis of material protection and sufficient spring hardness
