Run 'em.

 

Unless you take it to the track or really ride those tires to the limits, you'll be fine. Different manufacturers will heat up differently and slightly different characteristics, but you'll be ok.

 

Since the back tire still has the sticker on it, and the front tire only a couple hundred miles, i am just gonna run them, i wont be taking it to the track any time soon, and i have spent to much in mods already to be replacing perfectly good tires. Next winter i will put new shoes all around.

 

I had to run qualifiers on the front and pilot powers on the back after getting a nail out in the middle of Nevada. The shop in Reno only had pilot power so I went with them. The bike didnt handle the same afterwords, but after I got used to it I was able to run them just fine in the mountains of CA. Dont waste your money, wear the tires out and then get a matched set.

 

on my last few bikes,
86 gsxr750
87 hurricane 600
89 zx7
92 gsxr 1100
93 cbr 900rr
95 fzr1000
96 cbr 900rr
98 r1
2001 996
2002 r1
06 cbr1000rr
always ran mismatched tires- never any issues

 

but if you had matching tires would you have owned so many bikes haha jk, I am gonna run em for now, then i am going back to my qualifiers i think.
