YOSHIMURA YAMAHA YZ250F 19-23 YZ250FX/WR250F 20-24 RS-12 STAINLESS FULL SYSTEM
It's here! The RS-12 for the Yamaha YZ250F!
After over three years in development and testing, Yoshimura are pleased to announce the RS-12 is here for the Yamaha YZ250F! With the help of incredibly talented factory sponsored athletes, technicians, devoted engineers and a will to raise the bar, the RS-12 has now arrived for the current Yamaha.
Yoshimura considered all the details when it came to the RS-12. One look and you can see it's like nothing else on the market. As you get closer you will notice the details in every place on this new dirt bike system, from the matte carbon fibre end cap with decal inlays to the precise machined joints, this system takes it to the next level.
RS-12 Features and benefits:
- Aggressive intelligently designed, the RS-12 asymmetrical shaped muffler allows maximise capacity and incorporates a resonance chamber for managing sound and increasing usable power. RS-12's unique profile also provides more clearance for tyre and brake calliper.
- Improved performance gains with refined linear power delivery.
- Just like the works systems our Factory Racers use, RS-12 systems utilise precision machined joints. Machined joints provide a superior and exacting fit for joints by better securing the seal between two surfaces with a perfect 360 degree contact surface which translates into improved system life, fit and performance.
- New patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound inserts and spark arresters.
- Works-look matte carbon fibre end cap with industry leading design, innovation and detailing as expected from Yoshimura.
- Carbon end cap covers the RS-12 inner cap, thus improving looks, while providing easier service as compared to other sandwich mounting designs most commonly found in the industry.
- Proudly designed, developed and made in the USA!
- Repack Kits, optionalĀ InsertsĀ andĀ Spark ArrestersĀ are available for all models
