Hi Norton 73, (Got 2 Nortons myself, the ones with the real frames tho)
Yes, it has a later /6 swinging arm and tank. XR 500 front end, 30mm amals, and recently put on the original heavier flywheel in place so I could put the electric starter system on. lost some response after having a much lightened flywheel on, buts is just fine. R90 S rear bevel housing for the road but have an R60 with lower gearing for the trails, but motor is torquey so i haven't used it much.
I tend to use it off road instead of my V Strom 'cos if that went down... OUCH!! The damage! Just did about 100 miles on the Strom this afternoon in the NC sunshine. Got to the snow level in the hills.
Happy Days Freddiefudpucker
