From: "Vic" Hello, thank you for asking, but there are no alu nose wheels for sale at present, maybe when I retire in two years ... Actually this was a very traditional (= time consuming) manufacturing process for a one-off, to replace a corroded magnesium rim . With a little help from CNC machinery one could possibly produce this at reasonable costs and achieve a superior replacement. This should give the shimmy damper an easy life then. So my idea in case of vibration problems would be to add some lead weights into the originals and have them balanced statically at least, a friendly motorbike shop should be helpful at that. The nose wheel offers only limited range of balancing, see photos. Maybe milling little pockets in the side of the separate flange to fight centrifugal forces for the weights should give reliable positioning combined with the sticky tape. For the main wheels there is ample space inside the cast wheel to balance. The geometric run-out of the rim is not so noticeable vibration-wise, I believe and you have to live with that. But I am working on a mod for modern seals ... As to Desser tires, none required at present, WLAC in UK supply Chinese tires - no idea if they are a good alternative. But shipping from USA to Europe is cost-prohibitive for us on this side of the Atlantic. Am I right in thinking that tires and wheels of 18 T and 52 are the same ? When producing replacements : Is there a legal aspect for the manufacturer like with certified aircraft ? Or in case of experimentals the owner is tinkering at his own risk ? I guess the pilot is in jail with one leg anyway.
