My L/H disc has become wobbly on the central web, the manual says 0.15 mm side play maximum, when I checked I had over 1.0 mm, more worryingly it has rotational movement on the web. Rattly discs are not uncommon on a lot of bikes but my R/H disc is like new, mileage is 27,000 and the L/H disc should have been replaced ages ago. I tightened up the rivets woith a hammer and a socket over the retaining washer which helped a lot but its getting worse again. On looking for replacements, genuine discs seem to be out of stock, EBC replacements are £185.00 each and I would need both but a general internet search brought up a Chinese company theat makes discs for a range of bikes including Guzzis. These are £140.00 a pair, much more reasonable, they have stainless rotors with alloy webs and look very nice, they also have 10 rivets rather than 6 which also seems a good idea. Has anyone come across these, if so are they good or bad or any other comments? These are sold via Ebay but a search on Ebay did not find them, I had to use Google which gave me a link to the Ebay page and that took me to their shop, the company is WUXI THAI RACING TRADE CO LTD. They list discs for a vast number of bikes, a lot of Italian one and seemingly most of thre bigger Japanese ones.
