I'm on the verge of completing 6000 miles on the CT, and reckon I have about 1000 miles to go before the rear needs replacing. Thing is, I can't see the front lasting much longer than that either. I had a similar problem with my previous bike, a Ducati Multistrada. Before that, I had Honda VFRs, and consistently had the front last the life of two rears.
Would have liked to get through another Pirelli Scorpion Trail before switching to a pair of PR4 Trails.
Does anybody get away with only replacing the rear on a CT, or do you always buy in pairs?
