YOSHIMURA RS-4 Signature Series Silencer made of aluminium with a carbon end cap, developed for Cross and Enduro machines. Designed by YOSHIMURA US and derived from work in the MX/US Championship, this silencer combines a racing look with a design intended for competitive use (FIM approval).
- Construction: aluminium/stainless steel body with a carbon end cap for a sleek aesthetic and resistance to thermal stresses.
- Architecture: 2-chamber system providing double soundproofing and limiting the typical resonances of high-performance exhausts.
- Approval: FIM approved, suitable for official events where this approval is required.
- Position: standard mounting position, designed to replace the original silencer on compatible models.
The RS-4 Signature Series stands out with its carbon finish and aesthetic designed for riders who want a compact and refined exhaust on their cross machine. It is aimed at owners of KTM and Husqvarna looking for an exhaust developed for competition, with a robust construction and a distinctive visual signature.
