Product details

The Yamaha YZ450F wins praise from media testers at almost every level, and Yoshimura set out to make riding big blue even better.

There is no shortage of power and torque on the YZ450F, so the focus was on smoothing the way both arrive. The new RS-12 delivered, boosting mid and top-end power along with torque. With a smoother transition, the YZ450F stays more connected to the dirt, leaving you free to concentrate on other things, like winning.

This RS-12 Signature Series system pairs durable stainless steel with Yoshimura's iconic aluminium silencer, and Yoshimura rates it as the best exhaust system for the YZ450F.

Key features

• Asymmetrical silencer shape maximises capacity and includes a resonance chamber that manages sound and increases usable power
• Distinctive profile gives extra clearance for the tyre and brake calliper
• Tapered silencer body inlet allows the system to sit further forward, helping to centralise weight without sacrificing performance
• Improved performance with refined power delivery
• Precision machined joints, as used on the works systems of Yoshimura's factory racers, seal with a perfect 360 degree contact surface for longer system life, better fit and better performance
• Precision Taper Fit (PTF) insert ring, patent pending, for easy fitting and removal of sound inserts and spark arrestors
• Works-look matte carbon fibre end cap with Yoshimura's design and detailing
• The RS-12 inner cap sits under the carbon end cap, which improves the looks and makes servicing easier than the sandwich mounting designs common in the industry
• Repack kits, optional inserts and spark arrestors are offered for all models
• Designed, developed and made in the USA
