Yoshimura R&D of America Announces 2011 RS-4 Applications
Published December 23rd, 2010
The RS-4 muffler was developed in conjunction with the Rockstar Makita Suzuki Yoshimura race team with one purpose in mind: winning championships. That goal was accomplished during the 2010 AMA Supercross and Motocross season when Ryan Dungey and his Yoshimura-powered RM-Z450 took the motocross world by storm as the first rookie in the history of the sport to dominate both series. The RS-4 is a unique design with predicated power, a side benefit of a quiet earthy exhaust note that speaks volumes for performance, and offers increased horsepower and torque. RS-4 systems are the choice of both the Factory Honda and Suzuki teams.
The RS-4 features:
- Polyresonant duplex chamber
- Two-staged stepped baffle
- Maximized muffler volume
- Innovative carbon cone end cap
- 3 muffler options: aluminum, titanium, or carbon fiber
- Titanium and stainless full systems available
- Low volume sound insert included
Yoshimura now has RS4 slip-on and full-system applications available for the 2011 Suzuki RM-Z450, 2011 Yamaha YZ450F and 2011 KTM 350 SX-F. Check www.yoshimura-rd.com for additional applications and updates.
