Yamaha R3 vs Kawasaki Ninja 300 vs Honda CBR300R Specification Comparison

Yesterday, the Yamaha R3 was officially launched, meaning there is now three serious learner bikes available which previously included the Kawasaki Ninja 300R and Honda CBR300R. In the neat future, the KTM RC390 will be widely available but in the interim, if you’re in a country that has stricter learner restrictions, these three bikes are what’s available if you want a beginner sportsbike.

Previously, we’ve test ridden both the Honda CBR300R and Kawasaki Ninja 300, with the green Ninja being our pick. While Honda may market the CBR300R as a small capacity sportsbike, in comparison to the Ninja it is definitely more of an all rounder. And despite it’s recent capacity increase, it’s still well down on the power figures of Kawasaki’s machine.

The Yamaha R3 therefore seems to be aimed squarely at the Ninja. It’s capacity of 321cc is 26cc more than the Ninja 300 and 35cc more than the CBR300R. And that translates to figures of 42hp for the R3, around 39hp for the Ninja and 31hp for Honda’s bike. Those figures are even more in the Yamaha’s favor when weight is taken into account. The lightest of the three bikes is the CBR300R at 364lb (wet), but the R3 weighs only 4lb  more with the Ninja at 383lb (that said, the Ninja 300 does have the largest fuel tank).

Obviously we haven’t ridden the Yamaha R3 yet, so it remains to be seen whether it can match the Ninja’s handling. However, reviews of the Yamaha R25 (the Asian version of this bike which has been available for some time which has a 250cc capacity) have been very favorable. And with the Yamaha R3 coming in slightly below the Ninja 300 in price and only $100 more than the CBR300R, Yamaha may soon reign supreme in the entry level market.

For now, check out the comparative specifications for each bike below.
