Default front tyre 120/60/17 or 120/70/17?

hi from a newbe
i have just swapped my fazer 600 for a 99 sv 650 naked,as soon as i rode the sv i had to have it brill bikes with great useable grunty power.
the front tyre needs replacing its a 120/60/17 i have been told that a 120/70/17 will be just as good and there seems to be alot more of the larger profile tyre to choose from,have any of you chaps used the larger profile and how did it differ from the smaller frofile.

thanks

kev james

i use a 60 and the difference is the turn-in rate with the 70 turning quicker.
U need to mod the front fender for it to clear the profile as the 60 is tight to the fender.

I like the 60 profile but the 70 is a supersport and super bike profile so if ur just doing weekend warrioring its better

With avon storm I prefer the 70 but it is small change. Not noticeable really if you are going from a different tyre anyway.
Numbers on side only vaguely resemble the size of the tyre anyway.

As far as I know plenty minitwin guys using 120/70 on stock fender.

I swapped to the 70 profile when I put a gixer front end on my bike and I have noticed that it tips into corners much faster Although this might be partly due to having different forks on the bike.
As well as making the bike handle a bit sharper, it might be a good idea if you do lots of fast riding as you'll have a larger area of the tyre in contact with the road at high lean angles.

SRAD forks are about an inch short, which helps too

the other option is to get a 110 tire is tad more expensive but has the same effect.
If your a speed nut it'll reduce stability also
