The Swap?!

[Ultimateshado...]

Yeahello, i’m new around this parts, so 1st of all, my name is Pedro, 28 and i’m Português.
i had gpz600r that tried to took way my legs in the divorce but thankfully, my lawyer is the bomb!
so now i was looking at my sym xs 125 k and decided to mess around with it. the engine was busted so… went out the window. i’ve been looking, and i know that this is hard but ear me out.
Imagine the frame of the cb500, the twin cylinder?! ok. so… i’ll need a lot of things, but i think the most importante will be to reinforce the frame on the engine bay “floor” of the 125
i know i need forks, electric, tires, brakes and so on so on.
my question to you, Gods of the bike is! will it bend?
let’s be honest… every measures is almost exactly the same. like 0,3 to 5% diference… so let the games begin

Thx

What?

I think he's suggesting shoehorning a 600cc IL4 into the frame of a 125 commuter and putting 69hp through its rear wheel.

This is an excellent idea and I heartily endorse live-streaming its first run.

Anything is possible. Doesn't make it easy or worthwhile.

The biggest problem, assuming the engine fits in the frame, will be getting the chain run to line up and fabricating engine mounts, then fitting the airbox. A CB500 engine will run like shit on pod filters.

Mounting the radiator would be tricky, the wheel and mudguard will smash into it.

If it did work, you'd have a bike with brakes and suspension designed for a 125. It would still look shit, too.

Sell the sym frame and buy a CB500. If you want to make something fun, start with something fun and make it better.
