Simons for pre 78?

Well there you go then ,learned something new today . Snowy post a pic of the Simons you have.

The answer to the question is yes, they are legal to run. I have a set on my rm125b and are restricted to 9". The Simons are all the same except for the length of the dampening rod which determines the travel (how far it extends). The staunchings are all the same length. Fox forks were not available in '77 so naturally not legal.
And what Tm Bill said. Even those husky forks may be legal if the travel has been restricted.

If Simons are all the same why does the MOMs copied from the US AHRMA specifically state "early model Simons" that are restricted to 9" travel ? and not just Simons that are restricted to 9" travel?

Maybe they are referring to early simons forks as pre USD Simons forks.

Makes sense  and those rules were written in A Maori car, home of the brave land of the lawsuit  They would need to be word perfect and cover all bases 

A Maori carn rules are probably not the best template for countries like Australia or NZ where common sense is used rather than call 0900 sue my arse off when things go pear shaped

I'm pretty sure all the Simons forks are the same other than the amount of travel. I've got a set of 11" travel Simons that are still 38mm, maybe the stanchions are longer but I could still restrict them to 9" travel and use them.

Emulators and modern shocks are legal in all eras as they are internal and not visible. Fork and shock internals are free the same as eng.

I haven't found that clause in MOMS yet , still reading.

I was under the impression emulators were not legal in pre 78 because it's a performance enhancing mod that was not available in the day...

def agree with TM

   Why wouldn't you can all the bull and blanket fix the lot ! pre 75' = 7"&4" or 8"&5" with 35/36mm tubes   ,pre78' = 9"&9" or 10"&10"with 38mm tubes -factory/aftermarket or restricted  !

length of the dampening rod is the only difference. I had three sets apart at once to compare.

Interesting... did you shorten the rods or put spacers on them to lessen the travel?
