Clutch tuning with Serpent SER909520 1.8 spring

The Serpent SER909520 Centax II/III Spring is engineered to refine clutch behaviour on Centax II and III systems. At 10mm with a stiffer coil profile, it provides increased preload compared to standard springs, helping achieve cleaner engagement without compromising coil spacing.

Effect on throttle and launches

A firmer spring lets you tighten clutch settings to gain more immediate throttle response and firmer launches. The coil spacing remains adequate to preserve smooth shoe movement and reliable contact with the bell across RPM ranges.

Installation and recommended use

Specifically matched to Centax II and Centax III clutch kits, this spring is suited to competitors and hobbyists seeking a more assertive clutch feel. Installation is a direct swap for users familiar with Centax maintenance routines.

Is special tooling required to fit the spring?

No special tools are needed beyond basic clutch disassembly tools. Work on a clean bench and take care to note shoe orientation when reassembling.

Will this spring suit both street and track use?

Yes. It is versatile for track sprinting and spirited street runs, though you may need to adjust clutch clearance to match surface grip and driving style.

How do I test the new settings safely?

After fitting, run short low-speed checks and gradually increase throttle. Confirm shoes engage evenly and the engine does not stall under load before full-speed testing.
