Well I have a 3.5 nc30 rim on the front now which uses a 120 and realy doesnt do much for me but its got them pre-war gpr70's on.

I used a 120/70 rather than 60 profile on my motard which is meant to help with soaking up chatter so iam lead to beleive, and was curious if the 16' front with the 120 what ever size on the front would offer even more radius on the tyre such as the 16.5" tyres do at the moment (meant to have larger contact patch whilst bent right over)

So apart form the tyre size steve, did you track it? or feel any difference of any kind on the asphalt positive or negative?

As for tyres well I have used diablos on a light weight bike already, non h rated and they worked fine, got upto heat within 2 laps and stayed solid all day.

Any how all just an idea at the moment as i have just seen a cracking KR1s on ebay with me name all over it
