S3 Inertia mass ignition Idria Sherco RotorRef : SPART00308A / 1079822

Inertia Mass S3 – FW-SH-12
Developed for trial and enduro engines, this S3 inertia mass is installed on the Idria ignition flywheel of Sherco and Scorpa. Designed by S3, a specialist in trial parts, it meets the expectations of riders looking for a more linear engine behaviour and a more serene ride in technical areas.

• Complete kit ready for installation: inertia, screws, seals, and separator included.
• Allows adjustment of the rotor's inertia for a more progressive engine response and better-controlled accelerations.
• Suitable for cross/trial practice: facilitates riding at low and medium speeds.
• S3 manufacturing, intended for Sherco and Scorpa machines equipped with Idria ignition.

This rotor is particularly interesting for riders looking to refine the feel at the handlebars without altering the base mechanics. It integrates easily during a magnetic flywheel service and is suitable for both trial riding and more demanding use.
