More details from EICMA, Honda Press Release
2014 HONDA CBR300R model updates and tech specs, CBR250R upgrade | Rush Lane
The CBR300R’s DOHC 4-valve engine retains its 76mm bore, but stroke is increased 8mm to 63mm to give a larger 286cc capacity. Compression ratio remains 10.7:1 and peak power of 30.44 HP arrives at 8,500rpm with peak torque of 19.9 lb-ft at 7,250rpm a modest increase from the CBR250R’s output (26 hp @ 8,500rpm, 17.5 lb-ft @ 7,000rpm
Countering extra vibration from the longer stroke, the balancer shaft is heavier and the engine’s frame mounts are stronger.
So CBR300 is expected to vibrate more?
six-speed gearbox’s final drive ratio has been lengthened for more efficient highway cruising. Returning 30.2km/L, it can cover over 390km on one fill-up of the 13-litre fuel tank.
thats what, 71mpg?
The riding position has been subtly altered – while seat height remains 785mm, ground reach has been improved with a narrower, re-shaped seat.
might be harder on the bum, I don't think the pegs have been altered.
