I put my RideOn in my tires and put about 160 miles on to make sure it was well spread around. Checked my accrual mileage after installing my auto Tune Two up running around 60 most of the time. But meeting speed of traffic fast. We got 33.9. Not bad I was only getting about 34.5 to 35 out of my Ultra classic Both stage 1 with tuners, Riding the same way... The ultra was a 96" this is 103". I'm hoping bout the same pulling the bushtec with the trike as we got with the Ultra... Should have less wind drag since were wider now... Didn't notice any difference with the RideOn. But the trike only had 3400 miles on it when I got it.... Put it in for the stop leak...
