What's that got to do with VMX? You ask. 

Well, the previous record was held by a 1981 KTM 495, Prince of the big bore evo bikes! ('81 Maico was the King, of course).

I vaguely remember reading a magazine article about it and the only mods to the KTM were very tall gearing and removal of the front mudguard.  I don't remember what speed the KTM did but these guys can't have beaten it by much.

tim i think the ktm did 125 mph not sure but i have that article will look
it up

[VMX247]

its cool its a HONDA

[OZYKTM]

I think we still have it  123.75MPH

[Lewo81]

I believe 123.75 is correct. Nothing special done, just the tallest gearing, largest diameter rear tyre
they could find and hold it flat.

[OZYKTM]

Hard to imagine doing that speed on a dirt bike.

[Rosco400]

Especially on a KTM

[OZYKTM]

What no records for maicos rosco shame.

[holeshot buddy]

shit i was close with that guess
and remember 495 ktm
was more powerful than 490 magos

[Rosco400]

What no records for maicos rosco shame.

Yeah, doh! urban myth has it a Maico recently fetched 120K thats gotta be a record in itself

[OZYKTM]

Only in your dreams Rosco

when i had it my gme 500 would easily do 180 kph ,just set up for trail riding ,  what,s that in miles /

[OZYKTM]

Not quite fast enough.180 kilometer/hour = 111.846 814 6 mile/hour (mph)

Those guys should be ashamed not proud. Beating an 81 model lawnmower technology bike in std trim. With state of the art technology modded to buggery by 3 mph. Admitedly it is KTM vs Honda. But 27 years should of cought up with the great white god of bikes by now. Or was the KTM just so far ahead. I think the latter.

Back in the early 80s many of us used to take our bikes to the old Castlereagh Dragway for the Saturday night bracket races. The king of the group was Chris Ellis on Husky Imports stock as a rock CX500 Husky which regularly ran 11.9 ETs at 106mph, going through the traps in 5th gear, another gear to go. Geoff Ballard could only pull mid 12s at 99mph on his 490 GS, Geoff Eldridge on his Finke KX500 could only low 13s. I remember beating him one time on my 81 490 GS and I gave away 20kg. My 490 ran low 13s at around 93mph and my '79 Magnum 400 ran mid 13s at 88mph. Bernie Ellis ran consistant mid 12s at 100mph on his 465 IT Yamaha, fitted with YZ top end. Those 6 speed 500 Huskys were weapons in a straight line. There were more drag racing dirt bikes but they are the ones I remember. Chris and I still have our time slips to prove it.

I recently saw a photo of a YZ450F in a drag racing magazine running a mid 12 second second run. It seems that the old 500 class bikes still have the speed over the new stuff. In the early 80s Wheelsmith sponsored a 490 Maico in California that was lowered, stretched out and raked like a pro stock bike that ran mid nines @ 130mph with nitrous.
