The Kawasaki ZX-25R has been the talk of the town ever since it was first unveiled. A quarter-litre four-cylinder sportsbike that revs up t0 17,000 rpm and has all the bells and whistles to be an ultimate track tool? Who wouldn’t be excited about it? Kawasaki though, all this while has kept mum about its performance figures. The power and torque output figures are out in the open now. Kawasaki hasn’t officially revealed but it was accidentally leaked by Slovenian exhaust system specialist Akrapovic.

More details

Akrapovic reportedly posted dyno test results of the ZX-25R after they tested it with their aftermarket exhaust system. They did it to showcase the improvement in the performance figures of this monster of a motorcycle and later took down the post. The brand is offering two exhaust systems for the ZX-25R of which, only one is street-legal. The exhaust system will not only accentuate its aural symphony even further but will also provide a slight bump in power.

According to the dyno test results, the stock ZX-25R makes 42 PS @ 15,350 rpm and 20.8 nm @ 12,500 rpm. After slapping the Akrapovic exhaust system, the motorcycle makes 43.3 PS @ 15,450 rpm and 21.5 nm @ 12,500 rpm. The whole motorcycling fraternity were expecting the ZX-25R to cross the 50 PS mark but don’t let these leaked performance figures fool you. The dyno figures measure the power sent to the rear wheel and not to the crankshaft. The performance figures revealed by manufacturers are measured at the crankshaft. The performance figures are generally 10 per cent higher at the crankshaft.

If we bring the above-stated fact into the equation, the ZX-25R will most likely make 45 PS at the crankshaft, making it more powerful than its rivals. In addition to this, the Akrapovic system is also 4.4kg lighter than the stock bike’s 8.9kg exhaust unit. Couple this with its already sprightly performance and we are in for a treat. Not us though, because most likely, the ZX-25R will not be landing on our shores anytime soon.
