CFMoto 450SR S Brings Multiple Upgrades to Twin-Cylinder Sports Bike

The CFMoto 450SR S introduces a new element to the Chinese manufacturer’s roster, as an upgraded version of the standard 450SR.

The base of the CFMoto 450SR S is the same as that of the regular 450SR, meaning a 449.5cc 270-degree crankshaft parallel twin-cylinder motor producing 46bhp and 29lb ft, which are both figures unchanged by the S’s new underslung exhaust system. It’s the same Euro5-homologated engine as used in the CFMoto 450MT and 450NK, and features a pair of balance shafts, as is relatively common in 270-degree parallel twins, to reduce engine vibration, and is all wrapped up in the same tubular steel frame as the standard 450SR.

Other changes over the standard bike include a new 240mm rear brake disc (up from 220mm) with a two-piston calliper. This is paired with a Brembo front brake system, with the 320mm single disc setup carried over from the standard 450SR.

Further, there are updated (and quite large) aerodynamic wings at the front, a single-sided swingarm at the back, traction control as standard (as is ABS), a slipper clutch, a 14-litre fuel tank, a five-inch TFT display, and a USB-C/A charging port. A top box is also available as an accessory.

Despite the (fairly substantial) change in swingarm design, the rear shock appears to be the same unit used in the 450SR, and the bike continues to roll on a pair of 17-inch wheels. CFMoto says the front fork is also “upgraded”, the hardware remains generally the same - a 37mm upside-down fork with adjustable damping. 

Some of the technical changes, particularly the switch from a two-sided to the new single-sided swingarm, have helped reduce the kerb weight from 179kg on the original 450SR to 175kg on the new 450SR S. 

Two colours are available for the CFMoto 450SR S: Zircon Black and Tundra Grey. The 450SR S will cost £6,499 when it lands in dealers in March, which puts it more than £1,000 more expensive than the 450SR (£5,599) and right around where Visordown understands the new Aprilia RS 457 (between £6,500 and £7,000) will be when it lands later this year. This means there’ll be some strong competition for the 450SR S.
