The namesake feature of the CBR300 is its 37cc increase in displacement over the 249cc CBR250R. The now 286cc engine remains a liquid-cooled Single, with the entire displacement bumped achieved via an 8mm longer stroke (63mm). The changes are similar to the CBR’s obvious rival, Kawasaki’s Ninja 300, which upped displacement 47cc from its Ninja 250 spec by stroking out its Parallel Twin.
Further changes to the CBR300R compared to its 250 sibling are revised styling to better ape its bigger CBR kin. The 300 exhaust is different and the bike utilizes a dual headlamp. The 300’s engine also gets a heavier counterbalancer to quell the Single’s vibrations.
Pricing is a nominal $200 increase from the CBR250. Of more importance is how the CBR300 pricing fares against its natural rival, where its $4399 base MSRP undercuts the equivalent Ninja spec by $600. In ABS trim the $4899 CBR retails for $400 less than its rival.
