And its weight isnt the only reason for that. With more displacement in addition to the advantage of an additional cylinder, the Ninja 300 basically left the CBR in its dust in any measure of performance (other than fuel economy). (98mm) Wheelbase 54.3 in. Despite the engine counterbalancer, a faint amount of vibration gets more pronounced at higher speeds due to the throttle required; 60 mph at 6,000 rpm isnt bad, but 70 mph at 7,500 rpm gets a little tingly, and we could see it becoming an issue after prolonged periods. A new cylinder headeasily identified by its right-side exhaust portand new exhaust system plus revised fuel and ignition timing settings for the Dual-Timing PGM-FI fuel injection help generate more top-end power and added overrev, and peak power now hits higher than before. The development approach for the CBR300R took two avenues: more power and torque and a much stronger CBR identity, with stronger visual echoes of its larger capacity siblings, giving a more direct taste of the CBR brand itself. A steel diamond twin-spar frame provides the backbone of the CBR300Rs chassis and features a rigidity balance carefully tuned for both a sporty dynamic in corners and stability at speed. And this is one of the CBR300Rs greatest strengths.
