Crap day. I'm following my mate today to give him a ride back from the dealer as he's trading his hayabusa in. We had been riding for about an hour and I'm following. I've always been careful to follow back and to the side of him. He's kind of lost and were coming up to set of lights that I thought we may be turning right. We go past 3 cars stopped in right turning lane. We're cruising and suddenly he jams on the brakes to stop (illegally) infront of the row of cars turning right. I hit front brakes on non abs night rod and go down and up his ass hard. I don't think any harley was going to stop as well as that busa. I should have been further back. We're a bit bruised and busa slid on side. Night rod has bent forks and scraped all way up the side. Feel so bad for him. He really looked after that busa. I've admitted fault and am paying excess but I wonder what a cop would say if he saw the incident.
