Kawasaki ZX-6R

Now, I could be set up with a devastating injury, but I am still burning the mid-night oil wanting to find out the very best bolt-on package for ZX-6R owners out there. Therefore in this spirit, I hustled the mechanically-minded Dave Smith down down-to the Carbontek dyno look with my ZX-6R, and a support of different pipes to test.First up was the Akrapovic Evo whole titanium system that's been on the bicycle for the past two months. A super-light, beautifully constructed setup, it's the lightest of-the three on check here (and the most costly). The fi nal portion of-the link pipe is surprisingly fat - suggesting a pipe perfect for battle tuners seeking additional peak energy. I was very pleased about the Akrapovic's mixture of sound, looks, weight-loss and power.When first installed, it made 118bhp at the wheel, six bhp over stock. About the test time it made 116bhp at-the wheel, giving us a great base figure for trying another two pipes. An afternoon's spannering by Dave found the Micron Serpent Hydratech and Yoshimura Duplex techniques bolted on and tried out.The results are on the dyno linen - and rather fascinating reading they are also. The Micron setup, with the Ultralite can fixed easily enough, but Dave had some problems obtaining the headers to match precisely with the radiator bracket. Run up on the dyno, the Micron gave an impressive 119.5bhp in the tyre, an of around 3.5bhp within the Akrapovic, and very nearly ten bhp on top-of stock.The Yoshimura set-up looks a little slack to start with. It employs the standard kawasaki mid-pipe involving the significant stainless headers and the titanium end can, and a number of the welds really are a tad untidy. But bugger me if it doesn't provide as good energy because the Micron. A tenth of-a bhp more than the Micron, at-a hundred or so rpm less, with a couple of lumps in the curves, the Yoshimura does much better than we expected.The final variable was the advancing - the Power Commander on my bike had a place improved to accommodate the Akrapovic program, helping to make the Micron and Yoshimura seem even better. Some further time on the dyno would have improved the shapes on the Micron and Yoshi a lot more. So, in conclusion, the Akrapovic looks most worthy of further engine tuning.The Micron is cheapest, looks the greatest, and is the lightest by nearly fifty per cent of a kilo, makes joint-most energy, and is midway between the Akra and the Yoshi on weight. The Yoshimura makes shared most readily useful energy, is midway on value, and is largest. Now, ZX-6R entrepreneurs, the option is yours.
