The 130/90 looks good on the bike. It looks better than the 150 and is very close to the the same size. My calculation was that it was going to be 3mm shorter but on the bike it seems higher probably because it is new. It doesn't look much narrower although should be 20mm, it gives a less bulky look. I am use to running 130/70/18's and 17's on front, the Rocket is the first 150 wide front tire I've owned. I will let you know more later today if it doesn't start raining.
