Despite the rather idiosyncratic combination of the sensible 73.4 hp mid-range power unit and the extremely aggressive, sporty look, the R7 is by no means a sheep in wolf's clothing. The performance, which is somewhere between the R3 and the R6, turned out to be much stronger in practice than the pure values on paper would suggest, and in terms of geometry, chassis, brakes and tyres, Yamaha's engineers have really done their homework. On top of that, the Yamaha R7 has all the qualities to have a lot of fun out-of-the-box on a compact race track like the Pannoniaring, for example, even without a big investment. But of course it feels better on the country road, and that's where it belongs in the first place, in our opinion. In view of the overall package, the purchase price is more than fairly priced - so it's not a problem that the quickshifter is not included and has to be purchased as an option.

The Ninja 650 firmly stamps its predecessor (Er-6f). The engine has mastered the Euro 4 hurdle well and serves up a very usable 68 hp, the chassis is simply great for this class, and the weight reduction of 18(!) kilos compared to the ER-6f justifies reverent nods.
