I'll never go back to engine bars again. Carbon fibre head covers are the only thing which works plus you can take them off and on easy. I may get another set for on road as the first set looks very second hand after dropping the HP a few times on very sharp rocks. They are slightly scratched only, man the carbon are great. Bars would have never worked, those that did drop there bikes with bars bent them plus still damged the rocker covers with the sharp rocks. I would rather have no discounting at all then we would all be happy we got a good deal. This would also keep trade in prices up
