Kawasaki ZX-6R

Now, I could also be laid up with a debilitating damage, however I am nonetheless burning the midnight oil looking for out one of the best bolt-on package for ZX-6R house owners on the market. So on this spirit, I hustled the mechanically-minded Dave Smith off right down to the Carbontek dyno store with my ZX-6R, and a brace of various pipes to check.

First up was the Akrapovic Evo full titanium system that is been on the bike for the previous two months. An excellent-light, superbly crafted setup, it is the lightest of the three on check right here (and the costliest). The fi nal part of the hyperlink pipe is amazingly fats – suggesting a pipe best for race tuners seeking additional peak energy. I used to be fairly happy with the Akrapovic’s mix of sound, appears, weight reduction and energy.

When first fitted, it made 118bhp on the wheel, six bhp over inventory. On the check day it produced 116bhp on the wheel, giving us an excellent base determine for making an attempt the opposite two pipes. A day’s spannering by Dave noticed each the Micron Serpent Hydratech and Yoshimura Duplex methods bolted on and tried out.

The outcomes are on the dyno sheet – and fairly fascinating studying they’re too. The Micron setup, with the Ultralite can fitted simply sufficient, however Dave had some issues getting the headers to suit appropriately with the radiator mount. Run up on the dyno, the Micron gave a powerful 119.5bhp on the tyre, a rise of round three.5bhp over the Akrapovic, and almost ten bhp on prime of inventory.

The Yoshimura set-up seems a bit slack to start with. It makes use of the usual Kawasaki mid-pipe between the weighty stainless headers and the titanium finish can, and a few of the welds are a tad untidy. However bugger me if it does not give nearly as good energy because the Micron. A tenth of a bhp greater than the Micron, at 100 or so rpm much less, with a number of bumps within the curves, the Yoshimura does a lot better than we anticipated.

The ultimate variable was the fueling – the Energy Commander on my bike had a map tweaked to go well with the Akrapovic system, which makes the Micron and Yoshimura look even higher. Some additional time on the dyno would have improved the curves on the Yoshi and Micron much more. So, to sum up, the Akrapovic is the lightest by almost half a kilo, seems to be one of the best, and appears most suited to additional engine tuning.

The Micron is least expensive, makes joint-most energy, and is halfway between the Akra and the Yoshi on weight. The Yoshimura makes joint greatest energy, is halfway on worth, and is heaviest. Now, ZX-6R house owners, the selection is yours.
