KTM also moved the crank up on the new SX65 Just like Husaberg did. Believe me I'm not a KTM lover, but it looks like a whole movement on their part.
the intention with the 'berg engine was to put the crankshaft closer to the centre of gravity of the bike, and closer to the green axle: on a two-stroke it will not make such a big difference because a two-stroke crankshaft has a lower inertia/weight. also, a layout like this would move the exhaust to an even more exposed position. this was not an intention on the 50cc engine (even though it looks like that in your nice illustration). on the 65cc engine, the intention for the engine layout was to optimize the intake tract. these bike have a minimum weight rule, and they are already at the minimum weight. r
Rasputin, I would have never in a thousant years thought of that. Again, thanks for answering those questions. Enquiring minds want to know! BlipBlip/HuskyRips
Thanks Blip for the info on the pre mixers. Did you get a load of the Maico breako? They're back. Looks somewhat old technology (engine cradling in frame) but some good components. The 500 2 stroke looks like a CR250 from the seat back.
If I was going to pick-up a Maico, I'd want something mid 70s to very early 80s. Always liked the look of the 1976/77 MAICO AW250
I raced a '78 450 and a '79 250. Only difference with it than your '77 is a rounded off tank and up-pipe but same wrap on the rear fender with the '78 frame. I'll try and find some photos.
