Here's the Kawasaki ZX-25R's power figures

Kawasaki’s little screamer can go against 400 cc bikes

We have had the occasion to report about Kawasaki's little screamer, the ZX-25R for the past couple of months and it has been causing a lot of excitement for Ninja followers. The motorcycle has been teased a lot by Kawasaki Indonesia releasing some Youtube videos of the bike being tested on the track and on a dyno to hear just how loud this little screamer can howl. However, we were still left to speculate about its actual power output — until now.

Akrapovic has been developing an aftermarket exhaust system for the ZX-25R and they have been thoroughly testing the bike on a dynamometer in order to produce its new exhaust system. However, they unintentionally leaked the power figures of the Kawasaki ZX-25R on their website after testing it on the dyno. It appears that the ZX-25R is capable of producing 42 hp at 15,350 RPM and 20.8 Nm of torque at 12,700 RPM measured at the wheel of a dynamometer. It should be remembered that power measured at a dyno’s wheel is usually lower than the indicated power figure as the power transfer from the engine crank to the chain drive results in an actual loss of power of about 10 percent. Thus, the indicated peak power figure of a ZX-25R would be more likely to be around 45 hp, which is still significantly impressive coming from a 250 cc engine.

In comparison to other bikes, the KTM 390 Duke produces 43 hp and 37 Nm of torque at 7,000 rpm. The Honda CBR500R produces 46.4 hp and 43.1 Nm of torque while Kawasaki’s very own Ninja 400 churns out 49 hp and 38 Nm of torque. In other words, the Kawasaki Ninja ZX-25R has power figures that are at par with most 400cc bikes out in the market and it wouldn’t even be allowed to enter our country’s expressways for having an engine below 400 ccs.

However, its impressive power figures don’t come without a caveat. Because it has 2 or 3 more cylinders than most 250 cc motorcycles out in the market, it is considerably heavier than most of its competitors. It would also have a higher fuel consumption compared to other 250 cc bikes, and it would likely be priced considerably higher than most 250 cc motorcycles if not closer to the price range of 400 cc bikes. After all, it cost a lot of money for the research and development of the new engine and it only makes sense for Kawasaki to pass along this cost to its consumers.
