Which frame

[madmaxx]

Hi,
I'm new here and this is my first post.
I have got 3 pit bike frames and would like any feedback on which would be the best to use on my new project.
All help appreciated
I am making a standard pit bike for my wee fella.

1st and second utilise an a-style swingarm, third uses a mono. So there will be a pretty decent difference in bike feel and handling. Personally I'd be going number 2 and even number 1 looks interchangable with it. Last frame looks a little bent.

What sorta money are you going to be putting into it and what style of rising are you doing?

As little money as possible. Just something to rake about on.
Can't see me jumping it. I just wanna pick the best frame before I spend time sanding it down and then painting it. Got a choice of 2 engines. Think they both 110cc. Serial numbers are LC152FMH DY082930. The other one is 152FMH DY092292. Are these the same spec engines?
Which rear swing arm would be best. A frame one or other one.
Cheers and great site

I actually thought frame 1 was bent near the back where the seat goes...
