Fit the 120 it's far better than the 110.

How? The 120 on a 3 inch rim will pinch up, and give a completely wrong pointed profile - which won't be at all similar to that on the back so best case scenario, the bike feels a bit funny, and worst case you'll have some serious handling problems.


Stick with the 110, as that's what the wheel is designed for. If you want a 120, fit a different wheel!

This comment speaks of ignorance to me. We have this thread open, and a person who has a 120 on his bike saying it's good, and he's happy (having changed to it out of choice). We have another person who also has a 120 on the front, but wants to change back just because he is concerned. It's quite possible he will not notice a difference, it's equally possible that the bike will feel 'nicer' or that it will be less grippy with a 110 on it.




I say that if you want to try a 120 on the front - go for it. It's not a significant size difference, I doubt it'll make any more difference than changing your tyre pressures, but if you're more confident - great. And it might be better!


(I have pilot power CT on the rear of my bike, no idea what the front is, when it's worn I might fit a 120/70 )

And what I'm saying is that the Fazers rim is not designed for a 120 tyre! Some bikes you can change the tyres on, for example the 6 inch rim on the back of my ZX9R can run either a 190 or a 200 tyre without it being an issue, as both tyres are designed for that size rim. The fazer however has a 3 inch rim, not the normal 3.5 inch for 120s, and as such the 120 tyres aren't designed to work with the rim! They'll pinch up and give a pointier profile, which then won't match the back at all and could at best, feel "okay", and at worst give some serious instability issues.


If you want a 120, IMO, fit a new wheel. Otherwise if you want a pointier profile, get a sportier set of tyres!


Having spent some time working at a bike shop you'd be amazed at some of the dangerous things people have done because "it felt okay to some guy on the net"!
