S3 Inertia mass ignition Idria Gas Pro extractor RotorRef : SPART00307A / 1079821

S3 offers a dedicated inertia mass for the ignition flywheel of Gas Gas Pro bikes, designed for trial and enduro sessions where feeling and control make the difference. This rotor affects inertia to smooth out engine response at low revs and facilitate handling in technical sections: more controlled acceleration, improved traction, and more predictable behaviour when the machine is revving.

• Application: dedicated to the ignition flywheel of Gas Gas TXT Pro (250/280/300).
• Rider advantage: better inertia regulation for more precise handling and optimised traction.
• Versatile: suitable for all levels, from leisure riders to competitors.
• Delivery: ready-to-install kit including inertia, screws, special nuts, seals, and separator.
• Option: available with or without a flywheel puller to facilitate disassembly.

Simple installation for those familiar with the rotor and ignition; ideal for those who want to refine engine behaviour without modifying the electronics. Manufacturer reference: FWK-633. Brand: S3 — category: Rotor. Associated universe: Cross.
