    2002 Sevenfifty goes modern/retro Cafe

    It is not decided yet, but most likely I will fit the shock mount in the kink as well and then later in the thicker main frame, this would reinforce it considerably. I have found Cold drawn tubing in 25x2 and 25x1.5mm now

    2002 Sevenfifty goes modern/retro Cafe

    2002 Sevenfifty goes modern/retro Cafe

    Was thinking about subframe materials, I am going for 1", 25mm tubing, but what wall thickness using "regular" black steel should I go for?, 1.5 or 2mm? Also considering Chromoly but I have heard that it is hard to weld as the material requires pre and post treatment to avoid cracking.

    Lowering USD fork?

    I solved it, using a pipe cutter I cut the top off then fitted an aluminum spacer and a washer towards the stop spring, then I rewelded the shock assy. Now I just have to fix the other one, should be easy as pie now that I know how it works. image upload no limit Fork is now lowered 50mm.s

    Lowering USD fork?

    And so the first hurdle, I need to open the piston assembly to be able to fit a spacer, but that wasnt as easy as I thought. I am afraid that this is a one piece unit, pressed in both ends. Does anyone have an idea on how to open it? End facing the bottom of the shock, threaded hole is where...
