188 HP! 2011 Kawasaki ZX-10R on the dyno

Dailies -



First, we told you that the 2011 Kawasaki ZX-10R would make 197bhp at the crank (207 with ram air), then we learned that North American Ninjas would lose about 20bhp thanks to problems passing EPA noise regulations. Now, a shop in LA has but a stock ZX-10R on the dyno alongside a de-limited one. The result? A LeoVince pipe and a new ECU map sees 188hp at the back wheel. Take that S1000RR.

This de-restricted number seems to verify Kawasaki’s official claim. Typically, power measured at the rear wheel is 10-15 percent lower than that measured at the crank due to frictional losses in the driveline. Factoring in that loss percentage, you have a power at least meeting and more probably exceeding 197bhp at the crank.

While comparing results from different dynos on different days isn’t terribly accurate since they all kick out slightly different results, the BMW S1000RR typically records a 184hp rear wheel figure.

According to the video, modifications to the stock North American ZX-10R were very small, just, “a tweaked ECU and LeoVince slip-on unlocking full power to redline.”

Here’s a nicer sound recording of a ZX-10R running a LeoVince slip-on.

Skank, I think you’ll finally be able to beat One Arm.

Thanks for the tip, A. Calliste.

    I’ve seen the 184.5 who for S1000RR at Leo Vince’s location. It was in race mode of course.

    Wondering what was done to the ECU.

    Wes, you’re really buddy buddy with those NYC guys, eh

  • GuessWho

    Yeah,Wes,whats the deal with you and “those guys”? BFFs? Lmao.

    Where is that top image from? Is that a Leo Vince exhaust – looks good!

    Also does the tweaked ECU map just bring the bike into line with ZX-10R in other parts of the world? Or would that be different? (ie – will Kawasaki’s ‘softened midrange’ adding to rideabillity still be there?)

      Yep, it’s a LeoVince. I’d made that sound video a week or so back when they released some dyno figures of their own. Turned out those were a bit on the optimistic side, so we never ran that story. Had it sitting around as a nice image for this one though.

    Horse Power Wars!!!!!!

    I wonder how usable that power is on the track? It would be interesting to do a few laps with no electronic aids and really feel the limit the power on the chassis.
