The RS-12 Enduro Series slip-on provides great performance 4.1% in hp @8,000rpm and 2% increase of torque @4,800rpm with spark arrestor installed. This slip-on includes our installed USFS approved spark arrestor, SA-19-K, to make is easier to roll right out to your favorite off-road riding area. A custom stainless Yoshimura heat shield is included.
