Yoshimura Stainless AT2 Street Series Slip-on for CFMOTO 450 SR-S / 450 NK (2023 -)

The CF Moto brand has been making a mark in powersports, most recently with the incredibly priced 450SR and 450NK. After investigating Yoshimura found these models have a lot of value to provide the enthusiast, so they jumped in!

The 450 SR has a fit and finish that is hard to beat for the price. After ride testing this fun machine/potential track day bike Yoshimura set out to add their own value to these bikes.

The AT2 Street Series slip-on with carbon fibre heel guard is designed to optimize power and man, did it! The 449cc parallel twin literally woke up! This bike now sounds 200cc bigger than it actually is, and the sound emitting from the 450 SR almost sounds like a (hush now!) Ducati! Check the video comparison. The dyno verified what was felt in seat time testing - this feels like a different bike! Gaining 6.3% max hp and a whopping 10% max gain in torque, and all this at almost half the weight of the stock silencer.

The CF Moto 450 SR/NK just got a whole lot more fun! AT2 styling, sound and performance on the 450 SR is absolutely stunning!
