Ollie Posted February 25, 2011 Report Share Posted February 25, 2011 Hi Everyone So my dilemma is this I ride a zx6r (J2) '01 (in UK) which has a recommended 120/65 front tyre profile. From looking around it seems this profile is obsolete however the Dunlop website recommends I fit a 120/60. This is fine as I'll be fitting Sportsmarts and they are available in both 120/60 and 120/70. So I thought I had it sussed but out of interest I looked at the spec for a newer zx6r which recommends a 120/70. I'm assuming I should take the website as gospel and fit the 120/60 unless anyone says otherwise? Secondly why the change in profile recommendation from old to newer models? And lastly what's the difference between the profiles? I realise one sidewall is thicker but they are the same diameter. Is it simply a difference in shape i.e rounder or pointier? And if so which is which? Hopefully the above makes sense. No doubt the answers are straight forward. Regards Ollie Link to comment Share on other sites More sharing options...
