Split personality, I fake being smart
JDubs said:So, just to clarify, youre saying Im more likely to drop (fall down on) the bike in corners with wider tires than OEM? Just want to be sure what youre saying
Pretty much.
About 1/4" oversize is max I would go when 'racing' and even then you cant use all the tread.
Unless you have a LOT of nice twisty sharp corners to use you will be lucky to get more than 1000 miles out of rear and not much more from front
I fitted a 10mm oversize front tyre on my Katana, it isn't possible to use all the tread with a 120mm tyre on 3.5" rim, your fitting in effect a 4" tyre on a 1.85" rim
The dark 'ring' is close to the limit of lean angle, I've since managed to get down 'below' the direction arrow on tread ('line' just below mudguard edge)

kinda an exapmle of 'how I roll'

120mm tyre is 'theoretically' 4.72" or almost four and three quarter inches wide. I measured mine as fitted and it's about 116mm or roughly four and a half inches wide when fitted.(4-9/16")
It's is the stock size for GSX750F with the same wheel though so I'm not too concerned
