4-1/2 dry track days (1/2 day wet = real slow since I'm a chicken) and <800 street miles on these dual-compounds off a CBR1000RR. They are 120/70-17 and 190/55-17. $100 for the pair or $70 rear only/$50 front only. Let me know if you'd like to see them and I'll bring them to Loudon for any of the TTD dates next week or October (no obligation). Leave a note on this thread or feel free to call 508.272.9199 Thanks! Drew
