Identify these

[TM BILL]

I have a bit of red in the shed i need to move as with the green and yellow its starting to look more like a greengrocers than a workshop 

But i want to identify what brand the aftermarket Pipe and swinging arms are 

Hope someone on here can help  Bikes are 78 /79 Cr 250s

Appreciate any help from those in the know 

This arm i have no idea

This pipe is fitted to a 79 CR 250 fitted with a 360 mugen kit

[TM BILL]

This arm was sold to me as a DG item  its been powdercoated red and is slightly different to the other arm .

Not entirely sure but the pipe looks to be the Mugen pipe.

I reckon the swingarms are by the same manufacturer, just from different batches, from memory the same swingarm fits the 78, 79 & 80 so they could be from different years.
They do look a bit different to a DG swingarm that I saw a few years back though.

[TM BILL]

Thanks Geoff  your name was suggested as the pipe builder by a previous owner  I put him straight though  I said no way Geoffrey would turn out an amatuer effort like that 

You probably right about same Sw arm manufacturer different batches  what manufacturer though 

Why are the shock mounts different side to side 

[GMC]

Why are the shock mounts different side to side 

From memory the swingarm is lopsided for chain clearance.

if it is a Mugen pipe look out Bill - very poor welds on the top section under the tank.  How do you go about pistons for the 360?

[TM BILL]

Thanks Ross  Pistons i dont  the Mugen is just here for sale on behalf . I wanted to know what i was selling before i advertise it 
The 250 is mine and i want that gone to  but would be nice to confirm what is fitted to the bikes before i advertise them .

I reckon they are both dg arms

[TM BILL]

Would they have been gold anodized from new ?

Both swingarms are repo DG that were reproduced about ten years ago, Genuine gold DG arm has strengthening arch in front of wheel then a gap and rectangler brace before swingarm pivot, the arms pictured have a solid plate top & bottom.
The pipe is a hand made copy, Genuine Mugen pipe is pressed with a seam and looks like a standard 250 pipe but fatter.
Can send picture of Mugen pipe if you please.

I have a DG arm here, yours are quite different, so Not DG. No help other than that.
