Yes Stig. If memory servs, I think they were tested at 172 mph back in '89 with the little restrictor cut out of the inlet rubbers. I reckon that speed would have been done electronically and not by speedo readings. Speedometers usually read 10% fast. The lad I bought mine from in 1990 said he had over 180 mph showing on the clock a couple of times during his year of ownership. I never did though.....Stig wrote:170 should be achievable on std gearing. I've lowered mine to 16/47 since the top speed run. There's nowhere safe to use that sort of speed around here anymore IMHO
With age comes wisdom.......and senility!!! Who are you again?

Performance Bikes timed a derestricted RU at 171mph.
1/4 mile in 10.70 secs with a 139 mph terminal speed.
Still respectable numbers today.
Restricted RU was 163.8mph
1/4 mile in 11.17 secs with a 125mph terminal.
Keep on keepin' on.
