Doing the yzf600 front wheel conversion at the moment, and I have bought a fzr 600 rear wheel for the bigger tyre. Will it be alright to run 120 70 17 front and a 150 70 18 rear? Or does the profile need to be 120 70 17 and a 150 60 18 rear due to the rear being a 18 inch. I am thinking of doing the 17 inch rear conversion (maybe) later next year.
Thanks.
