KTM 250/350SX-F / HUSQVARNA FC250/350 23-24 YOSHIMURA RS-12 TITANIUM FULL EXHAUST, W/ TITANIUM MUFFLER
Introducing the newest RS-12 titanium full system for the 2023 KTM SX-F Factory Edition/2023 SX-F250 and 2023 Husqvarna Rockstar Edition FC250/2023 FC250 to give the serious racer every advantage possible.
Our goal was to add bottom end performance and over rev of the new 250 engine and...mission accomplished! On the dyno the new RS-12 TI system adds 2.7% max power and 2.6% max torque, but its not just about the numbers. On track the RS-12 put the power in just the right places, while adding throttle response and pushing into the rev limiter at a less dramatic hit.
This new system is one of the few Yoshimura production motocross exhausts to incorporate a resonator on the header and in the muffler. The new header resonator unlocks bottom and midrange power to not only make the new Austrian bikes more powerful, but provides more rider connectivity.
Yoshimura uses only premium titanium alloy tubing imported from Japan. Using titanium keeps the system light - 7.9 lbs.
Developed and tested in the heat of over 24 months of factory level racing
Aggressive, 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
Improved performance gains and fit when compared to previous generation design
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
Works-look matte carbon fiber end cap with industry leading design and innovation end cap detailing as expected from Yoshimura
Carbon end cap covers inner cap mounted design improves durability, and eases servicing as compared to other sandwich mounting designs most commonly found in the industry
New patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound inserts and spark arrestors
Tapered muffler body inlet design of RS-12 enables the system to be pushed forward thus helping with weight centralization without sacrificing performance
Proudly designed, developed and made in the USA!
Repack Kits, optional Inserts and Spark Arresters are available for all models
