YOSHIMURA RS-12 FULL SYSTEM

Code: 242940S320

In a word, POWER! That's what our new RS-12 Signature Series complete systems deliver for the all-new Kawasaki KX250 motocrosser.

Our new RS-12 adds plenty of power to Kawasaki's new and improved 249cc powerplant.

The goal was to add more usable horsepower and torque to nearly the entire power curve.

Boasting a 4.5% increase in maximum horsepower (at 12,000rpm) and an increase in maximum torque of 7.7% (at 6,700rpm), the RS-12 moves the power where it needs to be!

Obviously the RS-12 has more features than just power.

Its machined joints, PTF sound inserts, asymmetrical shape enhance performance.

With a matte carbon fiber end cap and that Yoshimura bark they will make your KX250 the most distinctive on the track!

Yoshimura RS-12 and Kawasaki KX250 are ready for the podium!

Features and Benefits:

Aggressively and intelligently designed, the RS-12 asymmetrically shaped muffler maximizes capacity and incorporates a resonance chamber for sound management and increased usable power.

The RS-12's unique profile also provides more tire and brake caliper clearance.

The streamlined design of the muffler body inlet of the RS-12 allows the system to be pushed forward in the new Kawasaki frame, thus contributing to weight centralization without sacrificing performance.

Better performance gains with refined linear power delivery.

Just like the works systems our Factory Racers use, the RS-12 systems use precision machined joints.

Machined joints provide a superior and precise fit for joints by better sealing between two surfaces with a perfect 360 degree contact surface which results in improved system life, fit and performance.

The new, patent-pending Precision Taper Fit (PTF) insert ring simplifies the installation and removal of acoustic inserts and spark arrestors.

Professional looking matte carbon fiber case back with industry leading design, innovation and detailing as expected from Yoshimura.

The carbon end cap covers the RS-12 inner cap, thus enhancing the appearance while providing easier service than other sandwich mount designs more commonly found in the industry.

Repack kits, optional inserts and spark arrestors are available for all models

Proudly designed, developed and manufactured in the USA!
