2023 CFMOTO 450SR

449cc INLINE TWIN-CYLINDER, DOHC, LIQUID-COOLED ENGINE

The 272MQ engine is an all-new powerplant designed entirely in-house by CFMOTO engineers and the first CFMOTO engine to feature a 270° crankshaft firing order.
A 270° crankshaft imitates the sound and feel of a 90º V-twin. In contrast to the 360° and 180° parallel twin variants, the 270° crank provides a striking compromise between rocking couple and inertial forces with better primary balance than the 360° and a lower rocking couple than the 180°.

So what does that mean?

Regarding real-world rider feeling, a 270°crankshaft-equipped parallel-twin engine has power delivery characteristics like a 90° V-twin engine. This means maximum power and torque output is produced lower in the mid RPM range instead of in the high RPM range like a 180° crankshaft equivalent. This translates to a more eager and responsive ride, especially around town. Additionally, the exhaust note of a 270° parallel twin is thumpier, sounding remarkably like a regular V-twin engine, as well.
