Hey guys just bought my first ZXR400 got a 93 and I've got big plans for her! But one of the first things I need to get sorted is a new set of tyres. I've previously has a 2000 R6 which comes with a 120/60 front tyre as standard but most ppl I spoke to changed to a 120/70 profile and everyone I spoke to at trackdays has a 120/70.
Now I was wondering what the score is with the ZXR front tyre? I know the standard is 120/60 do most ppl stick to this or do they change to a 120/70? Just wondering what peoples opinions are on this? I will be doing some fast road riding and track work on her with the possibility of moving to race at some point in the future (if I can get fast enough!!

) so I am curious to know peoples opinions. I also get the opinion that most people would recommend the 090's or supercorsa's?
Cheers guys
