YOSHIMURA KTM 250/350 SX-F/XC-F 23-25 / HUSQVARNA FC250/FC350 23-25 / GASGAS MC250F/MC350F 24-25 RS-12 STAINLESS FULL SYSTEM WITH CARBON END CAP

Introducing the newest RS-12 full system from Yoshimura R&D of America for the 2022.5 KTM SX-F Factory Edition/2023 SX-F250 and 2022.5 Husqvarna Rockstar Edition FC250/2023 FC250.

The Austrian 250 engine that is the heart of the KTM and Husqvarna is a brand-new platform for the 2022.5 FE/Rockstar and 2023 machines. Yoshimura's R&D engineers focused on getting the new powerplant to carry power all the way through the range. Now, the RS-12 provides the racer a much more wider power curve while adding 2.7% max HP and 2.6% max torque. Better than stock, you bet!

This system and the new one they just introduced for the Austrian 450 models are the first Yoshimura production motocross exhausts 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 additional over-rev.

RS-12 Features and benefits:

• Aggressive intelligently designed, the RS-12 asymmetrical shaped muffler allows maximise capacity and incorporates a resonance chamber for managing sound and increasing usable power. RS-12's unique profile also provides more clearance for tyre and brake calliper.
  
• Improved performance gains with refined linear power delivery.
• Just like the works systems our Factory Racers use, RS-12 systems utilise 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 fibre 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.
• Proudly designed, developed and made in the USA!
• Repack Kits, optional Inserts and Spark Arresters are available for all models
