Putting a 150 on this bike isn't a death wish. IMHO that is pretty dang funny.Putting that larger tire on a 4 inch rim is a death wish. Good luck.
Many people have ran 150's on this bike for a lot of miles, including myself. I know for sure the PR3 I have on is better than any 140 made for this bike. Then again, I'm a rain rider, so my main focus is wet grip and longevity.
But yeah saying its a death wish is funny, because if I died from it then guess who my family can sue? The Honda Dealer for telling me the 140 on this bike is pointless and go to a 150. When I asked a quote for tires, he quoted me on 150's and I just told him the model of the bike and that is when we got into the tire discussion. Also, a BMW/Dacati/Triumph dealer installed my 150 and they even said there is no risk of putting a 150 on a 4 inch rim. They said going to a 160 would cause issues, but ofc I don't wanna go to 160, I chose 150 because that is what the PR3/PR4's are.
