Thanks for your help on this one Micky! But I think this one is going to be a hard one to find a photo of or the history....so the search is still on. Please if someone finds something please get ahold of me. Thanks again DG

Micky.....this bike was purchased off of eBay out of Germany and all I can find out is selbach made bicycles...but I'm not sure it is the same  company. I would love to find a photo of one to see what tank was used and how the seat looked.

It's all in your head......or your motorcycle's head that is. The RM's of that era had full hemi heads with no squish band at all. That will make a great road race motor (HIGH RPM) but sucks as a motocross motor. I would have it welded up and have a new combustion camber cut in it like RK Tek does. DG

About the sand cast clutch cover. I think it was made for the big clutch that they was starting to put in the late 1970 or early 1971 400 SB....it was 25mm wider to fit the big clutch. So to use it on the 250 they made a clutch push pin that was about 50mm long and about 13 thick. This was not the best setup! the smooth small cover was a lot better. You can make a better clutch setup with the small cover and a bit newer clutch basket that had the oil holes in the back of it....now I'm just rambling....I will shut up now. Thanks DG

I haven't ran the motor numbers to see what year it was made.....I guess what I was trying to say is you could have had this maico in 1972. I will use three maico SB 250 as a reference that I was the 2nd owner of and all three came from the same dealer 70 miles from me. One was a 71 wide frame and the other two where 72 narrow frames. All three had the same small full hub. The 71 had sand cast clutch and ignition covers, one 72 had the same sand cast covers as the 71 and the other 72 had the round covers on the clutch and ignition. All three was T transmissions. The 71 had the small tank and the 72's had the bigger tank. I don't know why maico put what part on a bike when they where building them....did they run out of parts and used what was handy? So yes this motor could be a 69 it doesn't matter.....you could have purchased a bike that looked like this bike and then made the frame mod. Thanks DG

You could of had a sandcast or round cover 71-72 I think it was more luck of the draw on what cover you got. If you was lucky you would get the round small cover. The tank is just a small maico tank that could of come on any  maico not just a 125. The front hub is correct also.....this is just a plan old 72 SB 250 maico with the shocks moved up. DG

I would say it is a 1972 modified standard narrow frame....I would also bet if you pulled the head and checked the cylinder it is stamped with a 72 date. DG

Canadian maico got me pulled off eBay for selling aftermarket maico parts by going to eBay and telling them I was selling counterfeit parts. Even the parts that I invented and made for a maico that maico never made was pulled off. I had made some drawings of a new clutch guide plate for the clutch, big and small clutch that would have (I think) made a world class clutch. It will never be made now because of what is going on with Canadian maico.....I have sold all my maico stuff and moved on to other bikes.....so who got hurt in all this? you the guy that rides a maico.....I will never put a cent into making a part for a maico again. You can thank Canadian maico for that! I don't know what John Caldwell is trying to do....but from were I sit it's not helping the VMX community and helping one another is what I loved about this hobby.

I had RK Tek cut a new combustion camber for it. The guy  that made the pipe and did the porting has a RM500 with a RK Tek head.....I rode it and it has one of the best power bands (he ported his and made a pipe) I have ever rode...I think it was better than my maicos. Do you think some of the counter shafts broke from running the chain to tight? If it is a problem I've got other motors.

This was a bike that I have been dreaming of building for years now but I couldn't figure out how to make the center port cylinder. This past fall I meet a fellow (Curt H) vintage rider that worked in a machine shop and was up for the challenge of turning a RM500 cylinder into a center port. This turned into a ton of work for him and he had to call in some favors from a friend (Bob B) that was a custom welder, he had to weld the exhaust port from the inside and part of the outside. Then I had to have a friend (Tim T) grind out the weld and port it. This thing was so much work that the friends have said never again will they make one. I also had (Tim T) make the custom Pipe. I have to give a big thank You to these three friends it was them that did it not me! The tank is a 79 CR125 that I was playing around with years ago I'm going to change the front so it's not so ugly. The bottom end is a 1981 RM465 5 speed with the 500 top end. I'm not a big fan of the RM500 4 speed I think it has some odd gaps in it. We are trying to get it done for a race on April 6th-7th and then this winter pull it back apart and rebuild it so it looks a bit better.
