Gonna swap them for something a bit more sticky

But would you recommend a 120/60 or 120/70 for the front?
I know the 120/60 is lower profile so will lower the front a bit and turn in sharper, but will it suit the Baghira?
Currently got a 120/70 fitted.
(Dont need advice on brand of tyre to fit, thanks, I know what I like)
Cheers,
Dave
