The HONDA CBR300R

The HONDA CBR300R

Date: 2015-02-13

The CBR300R was conceived with two major objectives, to provide the rider access to more power and torque as well as a much stronger CBR identity. Visual echoes of its larger capacity siblings give the CBR300R a more direct taste of the CBR brand.

Firstly, the liquid-cooled engine is now 286cc, which is achieved through a longer stroke. Increased capacity is only one part of the equation and the CBR300R has received a series of upgrades to take full advantage of this increased power and torque. Work centred on the engine's throttle response and power delivery, while a new CBR500R-style exhaust provides both an aesthetic and functional upgrade.

The CBR300R's DOHC 4-valve engine retains its 76mm bore, but stroke is increased 8mm to 63mm to create the larger 286cc capacity. Compression ratio remains 10.7:1 and peak power of 22.7kW arrives at 8,500rpm with peak torque of 27Nm at 7,250rpm. This is a significant increase over the CBR250R's output readings of 19.4kW @ 8,500rpm and 23.8Nm @ 7,000rpm.

Countering extra vibration resulting from the longer stroke, the balancer shaft is heavier and the engine's frame mounts are stronger. The PGM-FI fuel injection with its 38mm throttle bore has been remapped to focus on crisp throttle response through the rev range.

For the CBR300R, styling cues were taken directly from the Super Sport range-topping CBR1000RR with an angular silhouette and aggressive full fairing, colour-matched undercowl, dual headlights and steeply raked rear seat unit.
