Tuning Clutch Spring.

Made from a special steel which is more resistant to high temperatures.

The engagement point of a standard Zenoah connection with the standard spring FG7317/08, is about 5,000 rpm, so picks up pretty early so the engine can not deliver the full power. This Spring engages areound the 7.000 rpm, so a clear improvement in terms of acceleration.

Can be used in:

• TPS7025
• TPS7315/00
• TPS7320
• TPS7330
• TPS7330/01
• HPI15448
• FG7316
• FG7316/01
• FG67350
• LOSB5039
