Well spotted Marc- and drilled for weight saving!
Makes me wonder what that lump of concrete is doing there. Did the mechanic forget his proper stand and some punter offered this as a temp' loan. I can just picture those sexy simons legs grating on the concrete as it falls down.
Er yes or the Alloy RN500 tank with a $5 breeze block stonked through the side, smashed mag front hub yikes, trashed UDX 60s. But bit of a laugh, any C grade club MX racer these days has an tent awning off the back of his RV/toy hauler with alloy hydraulic lift work stand, water blaster, snap on tools and mechanic.
Heres the world champs factory bike in 82 propped on a chunk of concrete knocked out of the pit wall.
