Kawasaki fans rejoiced over the news of the 2011 ZX-10R, and its claim to be the most powerful liter bike on the market. Official power output was set at 197 hp and 84 lb/ft, which bests the BMW S1000RR by 3 hp. This still remains true for our motorcycling cousins over the pond, but in the Americas it’s wishful thinking. Kawasaki of Canada recently released official power numbers for the 2011 ZX-10R, and they were staggeringly lower. The American version will see a 20 hp loss, bringing the stock numbers to 176 hp and 82 lb/ft. The performance loss is due to changes in exhaust and ECU mapping required to pass strict noise regulations. This loss in power doesn’t take the ZX-10R out of contention by any means. It simply puts it in the middle of the pack. Far from the intended spot of top liter bike that Kawasaki intended it to be. However the engine blocks of both versions are identical. American ZX-10R owners will have to purchase replacement parts to recover the lost power in their machines. That is of course if they can afford aftermarket parts after plunking down the $13,800 to purchase the new ZX-10R.
