CB650F / Overview
The DOHC 649cc four-cylinder engine powering the CB650F is completely new and engineered to deliver high torque and response through the low-to-mid rpm range, especially below 4,000rpm.
The development team, mostly in their mid-to-late 20s, decided early on that chasing peak power at redline was off the agenda. On a naked machine, strong acceleration from a standing start, low/mid-range torque and mid-gear roll-on throttle response were targeted as the essential elements.
Crisp pick-up above 6,000rpm and – for the sake of reduced running costs – economical cruising at highway speeds was also a focus. The engine has also been designed to look good, with no external plumbing obscuring its lines. Sitting relatively far forward in the chassis for optimal weight distribution, the engine is truly at the heart of the machine.
The CB650F’s steel twin-spar frame has a tuned rigidity balance along with cast pivot plates and aluminium swingarm. The rear shock works directly on the swingarm and is matched to a 41mm telescopic front fork; the wheels are a new six-spoke design. Twin 320mm wavy front discs and three-piston calipers deliver the stopping power with 2-channel ABS fitted an option.
Available as an option will be a 35kW output version for A2 licence holders, featuring ABS as standard.
Crisp, aggressive lines and angular silhouette give the CB650F real visual appeal while the low centre of gravity, slim feel, upright riding position and wide handlebars give excellent control. An HRC-inspired White, Red and Blue Tricolour paint option provides the finishing touch.
