700cc 2 Stroke SuMo

Could have used a better chassis looks like a 50cc bike which is probably not the strongest frame
-
@Louis-James Yeah it looks a bit of a bodge job in places, but considering they built it in 2 days not a bad result.

@NINJA You know what, I was thinking the exact same about that swing arm, but didn't want to say anything and sound stupid.
If that's a 700cc smoker SM, then that swing arm is definitely not up to the task of putting down that power. It'll flex.
Shock absorber looks inadequate too!

@Calum They flipped the swing arm over as the sprockets are on the opposite side with the new engine and used a shorter shock to get it to work. It looks like they did not think it through enough and rushed the build. But then if you watch some of their other vids, that's a common theme. Kudos to them for actually getting it rideable, but I would not trust their work 100% and agree with both of you. A better choice of engine with the chain on the other side, say from a 500cc 2 stroke MX bike, would have been a far better choice and have less complications for-sure .

Yeah you could go and buy a Maico 685 if you wanted to? 82hp @ 101kg dry.
