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 ;D
-
its cool its a HONDA
-
I think we still have it ;D 123.75MPH
-
I believe 123.75 is correct. Nothing special done, just the tallest gearing, largest diameter rear tyre
they could find and hold it flat.
-
Hard to imagine doing that speed on a dirt bike. :o
-
Especially on a KTM :-*
-
What no records for maicos rosco shame. ;D
-
shit i was close with that guess
and remember 495 ktm
was more powerful than 490 magos
-
What no records for maicos rosco shame. ;D
Yeah, doh! urban myth has it a Maico recently fetched 120K thats gotta be a record in itself ;D
-
Only in your dreams Rosco ;D ;D ;D
-
when i had it my gme 500 would easily do 180 kph ,just set up for trail riding , what,s that in miles /
-
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.

But i don't think they have beat it yet? check the times but it will only be a matter of time im sure as you said technology has caught up.And it only took 27yrs ;D
-
from the information ive read there was a stock KTM 495 that did 199 KPH
i find it hard to believe that this KTM was the fastest bike up intil now. what about one of those new ATK 700 (are they 600 or 700? im not sure now) cc 2 strokes. wouldnt they be faster than a early 80's KTM 495?
-
There is one thing to keep in mind here. The KTM factor.
-
I have a shootout in a mag somewhere and I remember that the KTM495 was the fastest bike for those that had the balls but didnt handle as good on a mx track, but the writer did keep mentioning the power it had, he must have liked the scare factor.. ;D
-
The thing to remember is the KTM makes a lot of power reasonably high in the rpm band. This allows a high top speed and causes some of the grief on the MX track. All bikes since produce power lower in the scale, much better for it`s intended use of MX but handycaps the top speed. This is why no bike is able
to achieve a similar speed, they`re better to suited to MX. KTM themselves realize this and a test was done 10 years later with a 540 XC which I think with minor changes only went 108 mph. (around 96 in standard trim).There`s more to getting around MX tracks then sheer horsepower and all the manufacturers design their power output to suit what riders need and can handle usefully.

And to add another 'dirt bike' to the list, check out the Le Touquet reports on various websites.
from the BMW site: "BMW wins at Le Touquet!
For the first time, a BMW rider on an HP2 Enduro wins the ‘holeshot’ prize at Le Touquet beach race. In heavy wind and rain, and at speeds approaching 200 km/h on the sand, local rider Jean-Charles Lenain beats 922 other riders to the end of the three-mile (4.5 kilometre) straight at Merlimont."
200kph is about 124.3mph, and admittedly, it is a modern, Big bore 'dirtbike'.

More of an update on the BMW
BMW Husqvarna Motorsport is preparing to send a prototype bike into action for the first time in the upcoming round of the FIM Enduro
World Championship (EWC) in Lovere, Italy on 22nd/23rd May.
The bike, which will compete in the E2 class at the event, is built around the Husqvarna chassis concept and powered by the innovative and highly capable 450 cc four-stroke engine developed by BMW Motorrad.
Rainer Thoma, President and CEO of Husqvarna Motorcycles, explains the decision: “Back in February we signed up to race in the E2 class of the Enduro World Championship under the new name BMW Husqvarna Motorsport. This collaboration of BMW Motorrad and Husqvarna Motorcycles aims to pool the two brands’ expertise in off-road competition for 450 cc four-stroke machines.
"The forthcoming debut appearance of the prototype bike is the logical next step following a very promising phase of testing. Although our leading rider Juha Salminen will have to sit out this coming weekend through injury, we’re approaching the event in optimistic mood with our prototype bike, our other regular rider Marko Tarkkala and stand-in man Andreas Lettenbichler.”
Over the past few months, the people at the Husqvarna Motorcycles development department have been working closely with specialists at BMW Motorrad and Speedbrain to develop a bike combining the Husqvarna chassis concept with the innovative and accomplished 450 cc four-stroke engine developed by BMW Motorrad. The testing phase, which got underway at the start of the year, is now completed, and the bike will be entered in competition from this weekend.
“Our aim for the 2010 season was to be fighting for the title in the E2 class of the Enduro World Championship with the BMW Husqvarna Motorsport team,” adds BMW Motorrad Motorsport Director Berthold Hauser.
“With Juha’s injury and his absence from the next race as a result, that’s going to be tough. In order to be successful despite this setback, it’s imperative that we make best possible use of the available synergies. With the testing phase completed the aim now is to use this genuine Husqvarna with BMW G 450 X drive concept to be up there fighting for success and victories in the sporting arena.”
BMW Motorrad Motorsport will remain actively involved in off-road competition with the BMW G 450 X. The team is planning to continue racing the bike in the European and the German Cross Country Championship and a range of Extreme Enduro events. Meanwhile, the Husqvarna CH Racing team will continue to compete in the E1 and E3 classes of the FIM Enduro World Championship. The Supermoto and Motocross segments will also remain under the Husqvarna banner.

Brad (Mr KTM) Lewis had a twin carb 495 running alcohol with a GSXR 750 clutch fitted that ran 11's over the quater with myself at the bars.
-
I have no real idea of top speed we did, I'm sure to run 11's even high 11's you have to be around 240km but I could be wrong. We had to run the gsxr clutch as the standard one just melted we also ran a modified TZ rear wheel with a tiny sprocket and slick road race tire. We also had this mad low pipe that was like 125mm in the belly section.
Pulled harder than an 15 year old reading penthouse.

Mick, Chris did high 11s on a bog stock Husky XC500.The 106mph trap speed was achieved in 5th gear. He was clicking into top going through the traps. I'll show you the timecards one day.

The Great White
Very fast
Bill Nolan would be the man to ask as he won a national title on one.
The bike belonged to Brad Lewis.
Brad and his brother are top blokes and really know their KTM's.
Bill made some mods to the bike but only to get it to handle better.
Brad's brother made an exhaust pipe that produced more power which made the bike show all three number plates up a straight.

As the present owner of a G450 X - my PE 400 would blow it away with a fouled spark plug - maybe I'm doing something wrong ?

I've ridden and raced plenty of bikes both old and new and the only thing that can match those older KTM's was the last twin shock Husky XC 500.
A few years ago I used to ride the Narrabri cross country just for fun on a 390 KTM. The race had some very long straight bits and a fair bit of black soil roads. The looks of disbelieve as I almost sucked them off their new 4 stroke 450's etc even XR 650 just sailed past them, at the end of day a few older guys would come up and asked questions. The only non stock part was 15 tooth front sprocket.
The joke was if you could see a bike coming onto the road section no matter what it was you passed it thou there. Even the pro outright winner lapped me just before it one day and I passed him back with ease back in the road section he shock his head as I went by. A good XR 650 is good for 150KM on dirt so this thing was good for 170km easy.

My pe400's can do 110 to 130 on the stock gearing but that is quick through the bush my 400x spins the rear wheel at 100km and wheel is still up in 5th one of the 82hp maico 700's if I could save enough $$ I'd buy one so beasty really makes all my other bikes look like idiots but they are diffenent machines. ;)
-
Maybe at classic dirt we could make a very long drag strip and stop the bullshit.
Ill be on the KTM thou.
-
Urban Myth??? When I was a lad read an article re a guy flat stick on his CR480/500 in the Alice/Finke race - was absolutely gob smacked when he looked over his shoulder - guy on the 495 KTM dropped a cog and passed him - then kept going!!!!
Anyways - helps the legend if not true :D

With respect Michael, I own a PE400, have owned '81 490 and '84 500 Maicos, won a club championship on XC500 Husky and have ridden a 495 KTM. As good as the PE400 is (a very good bike), it's not in the same ballpark as those other bikes as far as out and out drag racing grunt. My money's still on the Husky XC500 (the 6 speed trans is the key in their good acceleration) with maybe the KTM second. As Slakewell well knows, my '84 SC500 Maico was a ball tearer in the HP department too so seeing the bike will be at CD7 with it's good 'ol boy new owner, lets do the drag race thing and see who's king of the hill. ;D

Yes I understand that Firko, you have a 400 I know but you don't want to sell it if you did I have a nos speedo and indicator indicator to put on it or I can put them on one of mine.
I don't want to sell my 400's either would be interesting I have always read that the 495 ktm is the one but wouldn't doubt the xc500 either for a big top speed.
-
Just found this very old post so thought it would be worth digging up, top speed always being an interesting topic.
The current record is held by a KX500, google "card board robot KX500" to see the current record holder. Unfortunately, I think really goes against the spirit of what this is about.
Knowing the original record was done on an otherwise stock bike, (stock plastics, suspension even tyres) the KX500 has gone way too far.
Not only has the thing been radically lowered, it has skinny road tyres and most of it's bodywork removed, a dirt bike? I don't think so.
I recently emailed Maico International with interest about doing a record attempt, as after doing quite a bit of research I figured a new Maico 700 (the special model soon to be released) with a claimed 100HP would be an awesome base for such a record.
Unfortunately for me, they already have someone in house who is aiming for the same record, so it looks as if their support is going that way.
Will be interesting to see how they go with the record, the new 700 should be able to smash through it while looking very much like a dirtbike.
