    Friend forwarded this to me, he knows Girl Wonder rides a GB-500...

    I laughed, from riding Girl Wonder's 'pumped' GB I know just how gutless GB-500's are. But I have to admit, it's novel. I bet it travels at the speed of smell.

    The Bugatti windscreen is cute. I bet you pick up 5mph on the top end when you flip it flat. :rofl

    That is super cool, but man-oh-man, I owned a GB and the motor was absolutely anemic - I'd bet it didn't make more than 30 RWHP. I can't imagine how slow this thing is and I wouldn't want to know what the oil temps are cruising at anything over 50 mph.

    That's a hell of a front tire on that thing - the original was very narrow. Changes the whole look of the bike making it much more retro. I approve.

    Looks like a nice setup, just needs a heart transplant or a Garrett GT12

    You think THAT'S anemic? You should try my Chang Jiang. 22 hp at the crank, and an all metal tub that probably weighs 80% as much as the bike itself!

    50mph downhill with a tailwind if you are lucky. But it's a HOOT!

    Enjoy the slow hacks and enjoy the fast rockets. They're both fun,,,

    Speed is relative. Sure it won't blow your hair back but still movement is nice in any form.I have a light Eagle-Spirit on an S-R 500,it moves O.K. It'll run 75-80 if you beat on it, but will do a steady 60 without much pain.
    I've seen this GB combo at Mid-Ohio and it's very sweet. I just can't figure why you'd put a chair on the right in the U.S.A. It seems a bit of a strech to get the "Proper English Style". I guess he won't be doing much passing anyway.

    They put those little rockets on Royal Enfields...

    having had an SR500 and 2 GB500's, I'd have to say the SR is a much better (poerful) engine. Plus, I can't imagine trying to steer a sidecar rig with clip-ons.
    No wonder it's for sale.

    If its set up as a uk outfit, it'll pull to the right like crazy as the lean out to compensate for the camber will make it practically un-rideble.
    Dont know about THAT slow outfit, this will be really slow.

    its a 350 matchless single, say 18 horsepower, it was my dads so we are attached to it & the chair was cheap so, may as well do it as a local runner. S L O W I S T H E N E W F A S T.

    We have this for motorway use so, what the hell.

    There are some left mounts in the US and they can be setup to handle quite well. Lean out ( or even lean in) needs to be played with to find the sweet spot but it can be done.
    The main issue is that the rider (driver?) cannot see well to overtake and pass anyone. A friend here had a left mount Steib on a Vincent and he said if he watched the eyes of his wife in the sidecar he woudl be able to tell if it was okay to pass or not. (Big eyes = don't pass).
    Seriously a left mount does take some getting used to even after the setup gets decent.
    But of course on this GB500 rig passing may not be much of an issue anyhow. Just kidding:D .
    Cooll looking rig though and it sounds liek it was well taken care of.

    I never had an issue with the chair on the left on the RGM. And I was at bumper-level when going down the road. It just required I pay attention and commit when it came to making my passes.

    All my rigs from here on out will have the chair on the left because our racebike has the chair on the left. It would just be 'weird' to me to switch back and forth between left and right rigs.

    It's like running a GP shift pattern, either run all your bikes GP shift pattern, or expect to miss the occasional shift when switching bikes.

    Wonder if Motorvation built that Spyder for left hand mounting or if the seller modified it?

    I think Mary told me that had done a left mount spyder before. Wouldn't be that huge of a deal with that model.

    Just drill some holes on the opposite side from usual and flip a few parts over. Wonder if Motorvation's ever considered exporting?

    There may be more to it than that. I am not sure where the steel plates are inside the glass body on each side. We do not have on ein the shop right now. Is yours an early version? If not Can you tell on yours where the plates are?

    Mine was built during the winter of '93/94. The reinforcing laminated into the fiberglass looks to be pretty much symetrical, but on the right side it extends up a bit farther where the upper shock mount is.
