Hey I was on a run yesterday for 3 hours and the bike was running perfect, we got to the end of the run and suddenly the bike wouldn't move in Drive and reverse and with esp 1 2 3. So I got towed home 3 or 4 kms and jacked it up and the wheels will spin in reverse and drive but I have to give it more throttle than usual. But as soon as I put it on the ground it will move a couple of inches and thats it and I have to give it 3/4 throttle to get it to move that little bit. The drive shaft when jacked up in the air fully spin and when on the ground you can see it turn about 1/4 turn before it won't move anymore? Any ideas???
