i have been told if they did not do this (get rid of stop box introduce speed limit etc) no PERMIT for the manx g.p would be issued this is from the top FIM not THE acu.
i,am told there where many issues at this years t.t (even 1 rider riding the wrong way up the pit lane during a race!!) so this is why this has been brought in.

o.k so quick trip to the dyno 2/3 gear find out what revs to jugde what is 60kph might go to 50kph personally or quick trip round the ind est behind your mate doing 60 kph and jugde it from that job done. 30 secs will take some finding on the road!!
