Clutch Springs kit Stage6 (Sport Pro 107mm)

Stage6 MBK Booster / Nitro clutch springs
Stage6 springs for original Minarelli / Chinese 2-stroke or Stage6 Sport Pro clutches, to adjust the clutch engagement point.

Stiffer clutch springs delay the clutch engagement. This allows the engine more time to reach a higher RPM, resulting in snappier starts. The springs must match the engine's power band and performance. General rule: the stiffer the spring, the later the clutch engagement point.

Pack of 3 sets of clutch springs with different stiffness levels:

• 3x soft springs (1.8 mm)
  
• 3x medium springs (2 mm)
  
• 3x stiff springs (2.2 mm)
  
• Suitable for scooters with Minarelli / Chinese Minarelli replica engines
  
• Suitable for original clutches and Stage6 Sport Pro clutches
