Burt, build date of January '85, they went to mono shocks later that year I think.
Wirespokes, I did consider a taller final drive at one stage but various discussions on this forum got me thinking I might be over-capitalising, and over-thinking it. It will run all day at (or slightly above) the highway speed limit between 5000-5500rpm, which makes overtaking an exercise in forward planning but otherwise keeps my licence intact.
Montmil, for sure I'll join in the conversations. It was you bunch that convinced me I should buy an R65 in the first place.
