“Transmission shift linkage falls off of the transmission spline bolt. It happened to me with less than 9000 miles. Apparently it is a common problem. I got stuck in 6th gear and there were many times on the way home I needed to not come to a stop with two on the bike. There was a few times it would have been safer to down shift on the road. The issue is a very poor design where the shift arm lever mates to the transmission spline bolt.”
