The CFMOTO 675SS has stormed onto the scene, turning heads as the middleweight sport triple everyone’s talking about. And at Yoshimura, we spotted the massive untapped potential in that snarling 675cc inline triple right away.

We didn’t just slap together an exhaust for it—we engineered a true power upgrade. Introducing the AT2 Speed Series full system; built around our legendary AT2 muffler profile for buttery-smooth power delivery, paired with our proprietary Integrated Sonic Chamber (ISC) tech that unleashes maximum tone and relentless pull from low to redline. The result...a powerful Yoshimura exhaust note that hits your soul, along with serious weight savings, and dyno-proven gains that transform your ride.

Performance Without the Penalty

Expect massive gains over stock: up to 7.05% more horsepower at 11,100 RPM and 7.4% extra torque at 11,000 RPM—all while staying 49-state legal! Yoshimura delivers the numbers you can trust and feel with every twist of the throttle.

Significant Weight Savings

Power is useless if it slows you down. The AT2 Speed Series slashes weight dramatically:

Full system: 11.7 lbs (vs. stock ~19.6 lbs)
7.9 lbs saved for razor-sharp handling, quicker direction changes, and better agility on the track or canyon roads.

And the sound? Pure symphony. That triple-cylinder howl mates perfectly with the AT2’s acoustics—deep, aggressive, addictive—without the headache of excessive drone or rasp. As if that wasn’t enough, the sleek matte carbon fiber heat shield elevates the look from factory-fresh to a head turning menace.

Available option for the 675SS is our Passenger Peg Removal Bracket. Made of aircraft grade aluminum and then powder coated to perfection. Includes all hardware you need to install.

Proudly engineered, developed, and built in Chino, California—Yoshimura quality you can count on, mile after mile.

Unlock the hidden beast in your 675SS. The Yoshimura AT2 Speed Series—it’s the upgrade your triple has been begging for.
