It's time for a new front tire on my '05 ZZR600 and I was wondering if going from a 120/60/17 to a 120/70/17 would be alright. And on a side note the tire that i have on there right now is a 120/65 but I thought the normal size is/was a 120/60. If anyone has any info. for me that would be grrrrrrrrreatly appriciated. thanks in advance!!!

 

Ya running a slick? 120/60 and 120/70 is pretty much the norm. And no, I do not recall seeing a zzr 600 manual in my stuff. So I am not sure on stock tires.
