Hi,
Does anyone have, ride, or race one of these ?
Just looking for any comments (+ or -) about this model.
I picked one up yesterday.
Thanks,
Bob
Bob,
I raced one and have some motor and carb parts mostly used for it. They were fast but the cranks were a little high wear. In used ones pay close attention to the case waterpump area.

Rob,I was "loaned" 1 in the late 80's/early 90's.(actually it was abandoned at a shop i worked at so i borrowed it!).It was a neat bike to ride-fun-and competitive in desert and grand prix races at that time.I don't know about mx because by that time i was done with moto!

Rob I have 2 and 1/2 of these bikes. One is ready to ride, one is all complete needs rebuilt. One is together no motor in the frame, Two motors that need to be rebuilt. This bike is faster and lighter than my 1978 GS6 175. Puts out more power than my 175. Wieght is under 200 pounds. Bike is a hoot to ride, the bike is as close as a modern bike as you can get. IF YOU DON'T WANT YOURS,I WOULD LIKE A CHANCE AT IT. Thanks goes out to my cousin Dennis. If you need more info give me a call 217 260 0237 Later Gary
Thanks gentlemen,
Cool ! - good reports.
Even though I normally like big bores, I've had a desire for this model for quite some time.
Gary, I remember when Dennis came up to Michigan to pick up one of those that you have.
This one is original besides the rear tire, and handlebars. And never been raced.
I've now spent about 8 hours in disassembly, inspection, and cleaning. Really, the only sad parts I've found were the rusty spoke nipples. The radiators are a bit tweaked, but I believe they'll come around. Shock has dampening both ways, but leaks a very small amount of oil when I jump up and down on it. I suppose it should be rebuilt. Can anyone recommend someone to do the shock work ?
The two models I'm preparing to ride this year are this bike, and a '72 Jackpiner.
Thanks again,
Bob
Rob,
On the rebuild check with Lee at Letko Cycles in Kansas City. He has done them in the past. I might have some wheels. If you are going to race 125's again remove the throttle and install a toggle switch.:D
Larry P
Bob if you need any parts books I can send you a copy. Just make sure if you take the head off that you use the 1mm head gaskets. Email me your phone number and we can talk. I have some extra parts. Also if you can find someone that will rebuild the rear shocks, I would like to know,. I have 4 rears to get rebuilt, and have exhausted eveyone I know. WP, Drew Smith,KTM Parts with no luck. Later Gary
Richard at MX-Tech rebuilt a 82 WP CR 480 shock for me last year, He did a great job of fixing somebody else's screw up (the first guy I sent it to for a rebuild) Richard used to work at White Brother's in the 80's when they were the US distributor, so he knows his stuff. He was very reasonable on price.

Gary, I do need a parts manual. Now sending my ph. # - thanks.
I finally found a 84 125 MX version. Craigslist mostly complete 100 bucks. Who is the 84 125 expert here ? I'll be needing parts, I think I can fix the clutch cover but missing the kick starter. (I just missed one on ebay)
Scott
Sorry Scott, I'm the one that got that kickstarter.
Gary Ellis is the '84 125 expert, he has several of them and I got my bike from him. Just so you know, a large amount of parts are still available new from KTM, body parts, pistons, cranks, full gasket sets, a lot more than I ever thought they would have. It aint cheap, some of it is extremely expensive (piston kits are $324), but at least KTM still has it.
Brian

Brian no problem I should have bid higher. I've already contacted Andre about the pistons 120 Euro about 176.00 us. Clutch cover is no longer available. Did you the cylinder also ?
http://www.enduroklassiker.at/
I had my dealer check a bunch of numbers and they showed the clutch cover still available I hope they didnt make a mistake. Its $130, but it showed in stock in Austria. If you go to KTM Cycle Hutt, go to the "search by part number" page and enter 501 which is the prefix for the 84-86 engine it gives you a long list of parts that are still available.
http://cyclehuttktm.com/FicheFinderNew/PartsSearch.aspx
I took numbers from that list, pistons, cranks, seats, etc and had my local KTM dealer check availability and everything I checked that was a good number on that CycleHutt page was in stock in Austria. I guess I may have to actually order some stuff to find out if they are right and the parts are still available.
Brian
'72 Berkshire
I didnt get the cylinder, I only bid on the kickstart assembly. My cylinder is good, but I have decided that you can use an '87-'97 piston if you have a cylinder than needs to be replated. The only difference in the '87-'97 piston is its .25mm larger in diameter, if you have one replated they can take out the cylinder and replate to match that slightly larger piston. The '87-'97 pistons are readily available new from Wiseco. I plan to get a second cylinder and have this done when I need a new cylinder in the future.
Also, I have not looked at it, but it is not impossible that the later '01-up 125 piston which went back to 54mm instead of 54.25mm could be used in the '84-'86.
Brian
'72 Berkshire
Brian-
I believe your correct about the newer piston. I remember talking with Tom Eidam at Casey a few years ago. I believe he was using a later piston. This could be the solution for my cylinder, looks like it lost it's piston skirt and put some fairly deep grooves in it. I planning on taking it to Carlson Bogan (He's the best locally) and see what he can come up with.
Scott
If anyone interested, I do have an 84/250 FS. Cleaned up pretty nice and MX version..
Adios, Tom Brosius
Just in case anyone needs a rod kit, I found one that will work. The 84-86 OEM rod from KTM superceeded to the '87-'97 part number. Pro-X has one listed for 89-97 and since the stock one superceeds to those years I took a chance and ordered one. The stock 84-86 rod is very narrow and not "H" shaped, this rod is an "H" beam shape and appears to be a little heavier than the 84-86 rod but all the other critical measurements, both pin sizes, big end width, length, are all the same.
I'll report how it works when I get everything buttoned back up.
Brian
'72 Berkshire
Brian, A while back I let Gary have 3 of these bikes. One nice runner, One pretty complete one that needed motor work, and one in a box. Which one did you end up with?
Dennis Jones
I got the "pretty complete one that needed motor work". The only thing it was missing really was the kickstarter which I snaked from Scott two days ago on eBay. :D
Gary and I talked about the bikes he had, that is the one that fit my budget and I dont mind a project. The Motoplat was bad, but I swapped on some known good parts and it actually started up quite easily, but had a monstrous rod knock. I took the engine apart and the big end bearing rollers were square and fused to the big end pin, it must have had 1/8" of radial play. The rest of the engine looks great, main bearings are tight, cylinder is good, even the piston is within spec. Once I get the engine back together all it needs beyond the normal cables and tires stuff is the WP shock need a rebuild. I'm really looking forward to riding this bike against the Japanese horde in MX.
Brian

Brian-
Thanks for the Info, now instead of a rod kit costing around 255.00 I can pick one up for under a 100 bucks. what does your clutch cover look like ? mine needs some work, but a little JB weld should do the trick.
The cover has the typical mag rot you see in all those bikes like the early 80s Honda CRs with the mag waterpump covers, but I have seen a lot worse. It can be fixed with some JB Weld, and my Dad has a small powder coating setup what I might coat the cover on the inside of those passages to keep it from rotting away more where I dont do the JB fix.

Hi Poggers,
For your info. A neighbor of mine has a new KTM 1984 125 cyclinder and bottom end with crank rod and gears (no clutch or ignition).
You can contact him via email -
[email protected]Merry Xmas& Happy New Year,
Paul
Paul-Thanks for the Info, I just sent him an email

Thats funny! That is exactly what mine looks like right now except mine is the MXC not the MX. I wanted the MXC because of the wide ratio transmission and MX tuned suspension. I notice yours still has the original front tire on it like mine does too.
Brian

The Pro-X 89-97 rod went in perfectly. The engine wil go back together in a week or two, then the shock is going off to be rebuilt.

Brian,
Is there an easy way to distinguish between the MX and MXC models by looking at the frame serial number or engine serial number ?? Thanks !
Dave McCullough
Dave,
The easy way to tell is the MX does not have a rear frame loop, and the MXC and EXC do. Also the MX has an internal rotor Motoplat with a smaller mag cover, the MXC and EXC both have an external rotor Motoplat. The MX right center case is actually different from the MXC/EXC because of the smaller mag cover. I dont know if you can tell by the serial numbers.
Brian

Brian,
Thanks for the info. Hoping it will come in handy for a bike that my neighbor told me about recently. I'll let you know.
Dave McC
I ended up buying the cylinder from Paul's neighbor. I bought a set of forks for 20 bucks as the ones on my 125 had some pitting going on. I also bought a 85 KTM 250 air filter cage off ebay for 5 bucks to replace the missing one on my 125. Just gathering up parts, I have a few bikes ahead of this one.
I have the parts manuals and the service manual if anyone needs them
Brian,
The info you provided came in handy today when I went to take a look at a bike my neighbor told me about. The bike has been sitting in one of his co-worker's backyard storage shed for many, many years collecting dust. The bike turned out to be a 1985 KTM 125MXC and looks to be be in nice spape and only ridden sparingly. The guy who owns the bike bought it new at the local KTM dealer here in Tulsa Jan. 17, 1985 and still has the original title. It is missing the front and side number plates but other than that appears to be complete and original right down to the Metzler tires. The engine turns over freely and seems to have decent compression so I'll bet is it will run with some fresh fuel and a little tinkering. This one has a disc brake up front plus the upside down front forks which I guess might be the first time KTM used this set-up on a production bike. I know it won't be AHRMA legal but I'm still leaning toward buying the bike because it probably would make a nice project and show bike. Let me know what you think. I'll be glad to send you a few pictures if you shoot me an email. My email address is my screen name on this site followed by @cox.net.

There is a complete 84 KTM 125 engine on Marks Vintage Swapmeet for $125 right now in Illinois. Mike

I enjoy rebuilding and appreciating Pentons!
1974 250 HS Pentons-1980 KTM 175-400'S
I've already emailed him this morning , hopefully I can get the both the pipe and the motor
Yes, I saw the ad for the engine on Mark's site this morning too but did not contact the seller. The ad is poorly worded and is hard to determine if he has the KTM pipe for sale. The pipe he has pictured in the ad is for a Yamaha IT200.
Dave McCullough
The other pipe is correct for the 125.
Dave,
I would get the bike anyway. You didnt hear it from me, but if you put on the '84 fork, front wheel, seat, tank, and radiator shrouds on the '85 you would have the same bike as the '84 and no AHRMA tech inspector would know the difference, wink wink. :D
All of the parts you need are on eBay right now, you could buy the parts for less than $200 probably.
Brian
'72 Berkshire
I was able to buy the motor and pipe, no luck on a kick starter assy yet.
Brian-
How's your 125 coming along ? are you planning on racing it at Gainsville ?
Hi:
New to the Forum and would like to know if anyone has a 1984 KTM 125 project for sale? Would also manual/parts list etc. Appreciate any help on this project would be appreciated such as parts sources and availabilty?
Thanks:
Tom From Missouri
