We got to work as soon as we could developing a system that would not only perform better than stock but one that would make the new 450s more controllable and more connected. Days of dyno and rider testing put our new RS-12 Signature Series exactly where we wanted it. Packing lots of punch for these two 450cc European machines.\u003cbr\u003eThis new system is the first Yoshimura production motocross exhaust to incorporate a resonator on the header and in the muffler. This new header resonator unlocks bottom and midrange power to not only make the new Austrian bikes more powerful, but provides more rider connectivity.\u003cbr\u003eSpark arrestor sold separately.\u003cbr\u003eDeveloped and tested in the heat of over 24 months of factory level racing\u003cbr\u003eAggressive, intelligently designed, asymmetrical shaped RS-12 profile allows maximized muffler volume that helps manage sound, add power and provide more clearance for tire and brake caliper\u003cbr\u003eImproved performance gains and fit when compared to previous generation design\u003cbr\u003eJust like the works systems our Factory Racers use, RS-12 systems utilize precision machined joints.
