This may be a particularly solitary obsession of mine, but I believe I've determined the model GB with the sweet aluminum fuse cover: Here is the link: http://suprememotos.com/honda/48996-1988-honda-gb400-tt-039special-edition039.html Here is the bike: 1988 Honda GB400 TT 'Special Edition' This makes sense, as Honda also splurged a bit on the fancy metal badges on the tank and side covers... ...and chrome front fender: AnNoGBer and anyone else, please weigh in, correcting and filling in any blanks, but, since this model appears to have only been sold in Japan (right?) I can't find an OEM parts fiche on any USA websites or CMSNL. Not sure if it is possible to track down a parts fiche for this version in order to know the OEM part #. These aluminum fuse covers have proved to be pretty rare in my experience--nearly every cover I've happened upon these past many months is the standard plastic supplied with all the other model GBs and XBRs--but the aluminium versions do sometimes turn up: I myself have acquired two of these aluminum versions, now on the shelf ready to go onto GB1 and GB2 when the time comes. What got me back on this track is I stumbled on a pretty corroded speedo on Yahoo auctions at a ~$75 price that also included the fuse panel and a scruffy silverish ignition cover--either a bad paint job on plastic or an aluminium cover with a sad life story: I asked which, and the sellers says it's the latter. If anyone is willing to pay to buy the entire speedo assembly including fees and international ship charges, and then expend the elbow grease in order to bring the finish on this one back to its shiny glory, PM me and I'll give you the link. Caveat emptor of course--I'm only going by the pictures and the seller's assertions that it is indeed the aluminium version. Likewise, If anyone wants me to keep my eye out for one of these aluminum covers in better condition or cheaper (as well as look for any other parts you are needing) as I scour the web for GB parts for my GB1 & GB2, PM me and I'll keep an eye out.
