Looking for a 1976 or 1977 Penton/KTM 125 MC/MX, project or any condition. Thanks in advance.

I am building a 77 MC5 with a 78 KTM 125 engine and internal rotor Motoplat, with a soon to install NOS .030 Penton Wiseco piston, and 1976 D-Akront wheels, but until I get the engine up to Gary Ellis to bore and rebuld, I wouldn't be able to even estimate the finished price. I would like to have it done for Mid-Ohio depending on Garys schedule of engine rebuilds. Mike

Mike, thanks for the heads up on your project......would you consider selling it before you do the engine? I think I can finish the engine, I've done a few of them in my day

I'm trying to get something to ride for Vintage Days and a couple of other events. I'm just about ready to assemble the 1984 KTM 250 MX project for Post Vintage but I really want a small bore 125 to ride and race.

Thanks Mike.

gooddirt that is very, very nice! Mike and I came to an agreement last night so I'm really excited about this 125 and now with your photo I have a goal to shoot for!

[Mike Rosso]

gooddirt, not to go OT but what size Bing carburetor came on the 125 MX MC5's a 34mm or 36mm ?

[454MRW]

Mike,
In my 76 engine parts manual the 125 shows to have a 32mm Bing 84 series carb, the 175 has a 30mm, the 250 has a 36mm and 400 a 38mm Bing.
The 12-1-78 dated service bulletin however, shows the 125 with a 34, the 250 GS with a 36, and the 250 MC and 400 with a 38mm Bing, and it is the same in my 78 engine manual. Mike

The carb I bought on ebay for the 125 turns out to be a 36 mm Bing 54/36/1220 if you know anyone that needs a 36 Bing let me know I can still make it work
