YOSHIMURA RS-12 TITANIUM COMPLETE SYSTEM KTM SX-F 350 2022-2023

YOSHIMURA RS-12 COMPLETE SYSTEM

Code: 262541S720

Our goal was to add low-end, over-revving performance to the new 250 engine and… mission accomplished!

On the dyno the new RS-12 TI system adds 2.7% of maximum power and 2.6% of maximum torque, but it's not just about numbers.

On the track the RS-12 puts the power in the right places, adding throttle response and pushing the rev limiter with a less dramatic hit.

Test riders even commented on how our system significantly calmed down the chassis making the bike feel more 'settled'.

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 cylinder head resonator unlocks bottom and mid-range power to not only make the new Austrian bikes more powerful, but provide more connectivity to the rider.

Yoshimura uses only premium titanium alloy tubes imported from Japan.

The use of titanium keeps the system lightweight - 3.58kg and gives it that much sought after 'works' look.

Aggressively and intelligently designed, the RS-12 asymmetrically shaped muffler maximizes capacity and incorporates a resonance chamber for sound management and increased usable power.

The RS-12's unique profile also provides more tire and brake caliper clearance.


Adding 5.9% more peak HP and 6.9% more peak torque, this RS-12 has all the makings of what can lead to many podium finishes.

Header resonator tuned for improved power characteristics and enhanced sound

Just like the works systems our Factory Racers use, the RS-12 systems use precision machined joints.

Machined joints provide a superior and precise fit for joints by better sealing between two surfaces with perfect 360 degree contact surface resulting in improved system life, fit and performance

Professional looking matte carbon fiber end cap with industry leading design and innovative end cap detailing as expected from Yoshimura

Carbon end cap covers Inner cap mounted design improves durability and makes maintenance easier than other sandwich mount designs more commonly found in the industry

New, patent-pending Precision Taper Fit (PTF) insert ring simplifies installation and removal of acoustic inserts and spark arrestors

The streamlined muffler body inlet design of the RS-12 allows the system to be pushed forward thus aiding in weight centralization without sacrificing performance

Spark arrestor sold separately.

The RS-12 was proudly developed, engineered and manufactured in the USA.
