Official: 2018 Honda CB300R Sports naked revealed | EICMA 2017

BikingMilbank BikeSocial Consumer Editor, John owns a KTM 1050 Adventure. He's as happy tinkering in the workshop as he is on twisty, bumpy backroads, and loves every bike ever built (except one). He's bought three CBR600s, two Ducati Monsters, several winter hacks, three off-roaders, a supermoto pit bike, a Honda Vision 50 and built his own custom XSR700. 

 

Weighing just 143kg, and with a 799mm-high seat, the 2018 Honda CB300R echoes the styling of its ‘Neo Sports Café’ stablemates – the new CB125R and CB1000R.

The DOHC single-cylinder four-valve motor – the same as in the CBR300R – makes 31bhp (23kW) @ 8500rpm and 20lb-ft (27.5Nm) @ 7500rpm, driving the rear wheel through a six-speed gearbox. Honda says the engine has been designed with a minimum number of moving parts, in order to reduce maintenance costs.

Low-friction piston rings, a high-density radiator and an iridium spark plug are all claimed to help deliver an economy of 85mpg, which means the 10litre tank should give a range of up to 186miles.

The frame is a tubular steel lattice, with a pressed steel swing-arm that’s hung from a single rear shock with preload adjustment. The 41mm upside-down forks are unadjustable, rotating through 40° with the fat bar-style aluminium handlebars offering a 2.3m turning circle.

The 296mm floating front disc has no hub, and is bitten by a four-piston Nissin caliper. Both the front and rear brakes feature ABS that’s modulated for front and rear distribution through an inertial measurement unit (IMU).

The headlight (the thinnest ever on a Honda), taillight and indicators are all LED, while the thin LCD dash shows speed, revs, fuel level and gear position.
