Description
The refined power on the KX450 now produces up to 4.4% of HP @8,600rpm and up to 4.8% of torque @8,400rpm. No wonder this machine is pulling holeshots now!
The RS-12 muffler has loads of features including the PTF insert system that makes changing inserts a breeze and an optimized muffler shape with added volume and brake caliper clearance. Optional spark arrestor SA-21-K available separately.
Yoshimura's RS-12 systems proudly designed, developed and manufactured in Chino, California.
- Rubber mounted RS-12 muffler dampens vibration to subframe
- Aggressive intelligently designed, the RS-12 asymmetrical shaped muffler allows maximize capacity and incorporates a resonance chamber for managing sound and increasing usable power. RS-12's unique profile also provides more clearance for tire and brake caliper.
- Improved performance gains with refined power delivery.
- Just like the works systems our Factory Racers use, RS-12 systems utilize 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 fiber 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.
- Repack Kits, optional Inserts and Spark Arresters are available for all models
