New metal – Honda CB650F/ CBR650F

On the surface, the 2017 Honda CBR650F and its naked sibling, the CB650F don’t look much different than their 2016 versions apart from their new graphic schemes.

The overall visual design, including their cascading header pipes are back, and the underslung silencer has only a slightly different shape. Underneath the familiar skin, however, are a few updates that further refine Honda’s two 650 models.

Honda has shortened the air intake funnels for the 649cc inline-four while adding a dual-pass internal structure (rather than triple-pass) in the exhaust to improve the overall intake and exhaust flow management.

The result is a four bhp increase in peak power output to 89.8bhp at 11,000 rpm, while maximum torque increased by three-quarters of a pound-foot to 47lb.ft at 8000 rpm.

Shorter ratios from second to fifth gear improve acceleration with Honda claiming the 2017 models can beat the previous model in a second gear roll-on by three bike lengths over 400m.

Honda has also added a new 41mm Showa Dual Bending Valve fork, which claims to improve rider comfort and handling, and which delivers proportional rebound damping with firmer compression damping while offering more travel (up to 4.7 inches from 4.3 inches). The rear suspension remains the same monoshock with seven-stage preload adjustment which is mounted direct to the aluminium swingarm.

Both models feature revised Nissin front brake calipers and 320mm wavy discsw, and two-channel ABS is standard.

The 2016 models already had LED taillights but the 2017s receive LED headlights as well.

The CBR650F’s fairing looks very similar to the outgoing version but now features some open gaps in the side panels under the seat.

The CB650F on the other hand has a much smaller radiator shroud, further emphasizing the angular shape of the fuel tank while showing more of the engine.
