The holes if looked at on a flat plane are about 75mm apart (equilateral triangle) with 2 points against the engine and 1 point against the frame (maybe the other way round -sieve brain!) and the frame is offset about about 30mm along 2 bends in the plate. The engine is mounted much as any other and alot stronger than some. It is fixed at the swingarm pivot, underneath the engine on eachside, at the top of the engine and at the front. It is an Africa Twin, RD04, commonly described as the one of the few bikes to have been designed by engineers and biult by them and importantly, they had control of the budget! No penny pinching!

    You speak of the NXV650 (not to be confused with the NX650V - the honda dominator) - a Dakar machine that is the proverbial unicorns horn. Honda went on to make the RD03 XRV650 for a year or 2 I believe as a homologated model then they brought out the XRV750 RD04, followed by the XRV750 RD07 and RD07a.

    The RD04 is the one to get for those of us who arent millionaires as it differs very little from the RD03 - capacity being one of the main differences but I believe geometry, frame, engine design and size etc are almost identical as well. Body work is largely interchangable as well.

    I believe all the RD03s were made by HRC and the RD04s made by ordinary Honda, but I could be wrong.
    I think the 650 was a homologation special to allow it run in certain classes of the Dakar.
    Dave Cornish (AKA Crasher Cornish) who used to write for TBM had a 650, it's probably now rotting in his shed in Gt Yarmouth, he was a big fan of ATs.

    I nearly bought an RD07 to ride upto the Artic Circle in 2003, looked at it in Lings at Watton, but I decided it was a bit too big an unwieldy.

    Put it this way...I've replaced steel components with aluminium ones to make them stronger in the past The range of possible steel strengths covers almost an order of magnitude.

    If it were me I'd just buy OEM ones from David Silver as per the above. Well actually no I wouldn't I'd get new aluminium ones made at work or be proper flash and make some carbon ones. But OEM would be a close second

    If they are 3D, not just 2D IYSWIM, OEM might be the easiest way to go. But then I'm no metal basher.

    Could you take one mounting plate out at a time, then put a glob of this in?

    No you wouldnt as they aren't available any more and while they do crop up on ebay now and again, I am NOT paying 30 for postage from italy!

    I only asked as I have a metal workshop down the road and he is quite free with off cuts so thought I would do it that way. I may have to wait for them to crop up in the uk then.

    Cheers all.

    Are we talking just flat pieces of metal with holes here or are they some complicated shape?
