Last week got a message that @ZDave was heading up to Toowoomba to catch up with family. Told him to pop around and grab the airhawk and give it a try. Trip went really well and he rode up with out the airhawk and fitted up for the ride home. His comment was it did make a difference Then he went on to inform me he averaged 3.6L per 100 on the trip up and back I want one
It's not that hard to do if you really want to. All bragging aside, 3.6 l/100 km is pretty good for a ninja. http://www.fuelly.com/motorcycle/kawasaki/ex300_ninja_300
Went uphill without it and downhill with it. That is a skewed test, sorry. But 3.6 is still very impressive!
