CBR650F & CB650F
The CBR650F and CB650F both get fruitier for 2017. Their 649cc inlinefour engine has an extra 4bhp, taking it up to 90bhp at 11,000rpm. The increase, which Honda say is most apparent from 5000rpm upwards, is due to shorter air intake funnels and a more free-flowing exhaust.
Combine the extra power with shorter gear ratios from second through to fifth, and the new CBR650F should get off the line faster than the previous model. Honda say it’ll pull three lengths on the old one over 400m during a second-gear roll-on.
Increased torque means 47ftlb arrives at a peak of 8000rpm, and the engine’s tractability allows it to pull smoothly from 1500rpm in sixth gear.
Fuel consumption is a claimed 59.3mpg, which should get you more than 220 miles from where you last brimmed the 17.3-litre fuel tank.
Up the pointy end is a new 41mm Showa Dual Bending Valve (SDBV) fork, which claims to improve ride comfort and handling, and which delivers proportional rebound damping with firmer compression damping. At the back is a preload-adjustable shock, mounted direct to the aluminium swingarm.
Revised two-piston Nissin front brake calipers work 320mm wavy discs, and two-channel ABS is standard.
Adding weather and aerodynamic protection, the CBR’S new front fairing also channels air into the airbox intake duct. From the fairing backwards the two models look the same, with minimal sidepanels sharpening up the rear and the clear-lensed LED taillight matching the crisp LED headlight.
The naked CB650F is much the same bike, with only the lack of fairing and clip-ons to tell them apart – replaced with a neat headlamp and binnacle, and a set of handlebars. Take your pick.
