Feedback on this frame?

[unit_mx]

Just found this alloy frame on the Pitboss website , looks a good length and wouldn't mind putting it into my honda for the time being just as a little experiment. Everything VM pitboss I have ever bought has been very good quality and the frame appears to be from the good ol' days of 04/05 when pitboss where at its peak.

My question is , would such a frame be of reasonable quality and greater durability than the stock crf50 frame?
The welds look quite nice and it looks quite strong but Im in dire need of some experts to tell me the good from bad as im not that familiar with metal.



Cheers

Because I would have to send it down to Adam at the gong which will cost around $20 then get him to brace it for another $40 then get it sent back for another $20 then pay $180 to have it sandblasted or bead blasted and powdercoated. Total cost $260. Preety expensive considering I can buy Bretto's five-o 1 incha for only $275.

Nothings concrete but I like the look of this frame , that subframe looks awsome.

its a good looking frame mate.....only thing i dont like is were the sub frame bolts to the frame i dont like how the brackets are welded on would be better if it was a complete cast if ya get me.......but other than that its pretty sweet how much is it?

dont know bout alloy?Get stock frame braced and just leave it?prob solved.My 88 orig frame was just braced and not painted looked ok,the bracing may hav been spayed silver to match frame.
Oh and my 5-o frame sold payment pending..

I never claim to be an "expert" ... X is an unknown factor and a spurt is a drip under pressure ... but those frames aren't for rough treatment or jumping ... Motard ... yes ... Once again ... my relo bought one ... then didn't believe what I told him when I inspected it ... so he enquired at various shops and got told exactly the same thing ... ... It took a while but Davo doesn't question me anymore ....

You never claim to be one but you wouldnt need to claim to be an expert coz all anyone needs to do is read just one of your posts to see that you know what your talking about and that you are full of experience.

Yes the welds are good ! But it's not the welds that are the problem ... it's the tubing section that the back bone/spine is made of ... Size for size ... aluminium is far weaker than steel ... get a piece of steel pipe , angle it off a curb and drive over it in a car ... then get the same section of alloy pipe and try it again ... People will learn extremely quickly that way (destructive testing) ....

Incidentally Davo looked like this ... ... when the foot broke off the aluminium stand that came with the exact same frame as above ... and the weld was still intact on the foot but simply hadn't fused with the stand leg ...

When viewing welding ... think of it as being the same as sewing ... A good welder can can put down some perfect stitches ... but that doesn't mean he can put together a mean set of jeans ... Welding without metallugical and engineering fabricating design experience means zilch ...

Incidentally most bridges have NO welding on them at all ... they are rivetted for safety reasons .... Welds crack and fail when subjected to cyclic loading , expansion and contraction ... vibrations come under cyclic loading ... they destroy things by quickly bringing them to the end of their load cycle life ...

Righto , thanks for that Cactus.

So she's not as strong as it look , I sort of expected that but Im not hitting anything too gnarly on my little honda as its preety much impossible to do so on the stock forks , pegmount and rims without folding the bike. So no Tj Russel riding.
