Yamaha R7 Vs. Kawasaki Ninja 650 – Specification Comparison

Written by Nizam Shaikh

The middleweight motorcycle segment is slowly shifting from the earlier four-cylinder mainstream motorcycles towards twin-cylinder models. The trend shift started when Aprilia introduced its RS660 supersport and Tuono 660 sport naked motorcycles. The introduction of the lightweight, agile, affordable yet powerful twin-pots in conjunction with the suffocating new emission norms (Euro5/BS6) led to the demise of legendary motorcycles such as the Yamaha YZF-R6 and the Kawasaki Ninja ZX-6R.

Now Yamaha has introduced a new motorcycle, which seems to fill the void created by the discontinuation of the YZF-R6. The Yamaha R7 recently made its debut in the international market. The new supersport borrows some of its mechanical parts and the engine from the Yamaha MT-07, but it is not just an MT-07 with a supersport body. Yamaha has heavily re-engineered the chassis and added new parts to give the R7 its own identity.

But the CP2 motor is carried over from the MT-07/Tracer 700, and why not? After all, the engine is based on Yamaha’s Crossplane Concept and it is a worthy rival to Team Green’s Ninja 650. Kawasaki has also updated the much-popular Ninja 650 to BS6/Euro5 standards, and the motorcycle features the latest generation Ninja family design language, drawing inspiration from the Kawasaki Ninja ZX-6R. 

But this article is not about which motorcycle looks better. Here we pin the latest kid on the block, the Yamaha R7, against the tried and tested 2021 Kawasaki Ninja 650 in a technical specification comparison.
