    So, I was just posting in the "Bike you want today" thread. AND, on this particular day, I was thinking, "I want a big-ass thumper, set-up to ride in a sporty manner on the BR parkway, to keep at my place in the mountains." Sure, I love Sumos and have had a couple and that was what I was initially thinking about. BUT when I was poking around, I ran into the MZ Scorpion, which I remember from back in the day. It's a cool looking bike, that I am pretty sure was German. It used the Yamaha 660cc thumper, with a 5 valve performance head (built by Yamaha, if memory serves), and wrapped in sport bike (at least for back in the late 1990s) frame and nice suspenders, brakes, and brakes. Also, I have a weakness for oddball bikes. I started poking around, and there are a few for sale and they are pretty cheap. Yamaha engine = pretty reliable, can find parts.

    I think I might get one.

    Am I crazy? Should I call a doctor? Anyone know anything about these peculiar machines?

    Interesting bike! I had never heard of them until now. Go for it I say! If they're cheap now I would say they will potentially be worth more down the track given their rarity and good looks.

    The MZ's are great, I flogged a Black Panther Baghira for 25,000 miles. It was bullet proof.

    You could say I know a little about them. My son and I raced one for a couple of years (mainly him). Fantastic machine, wish I had never sold it. 100% reliable, handled great, not super fast. It was the perfect bike for him to start racing. I've said I'll buy another one some day. Get it, you'll love it!

    For some reason pics aren't loading. I'll fire some up tomorrow.

    Call a doc and donate the bike to me :lol3

    Nothing wrong with a single in a sportbike chassis.
    I sure wouldn't mind a scorpion or a supermono.

    Great bikes. XT660 engine with 5 valve top end from the Raptor quad. Frame was designed by Seymour Powell of Norton F1 frame. When they were designed the frames were intended to be held together by glue but production problems led to a standard weld. Really tough engines, I´ve heard of Travellers with 75k miles with no problems. I had a Sport and it was a surprisingly comfortable touring bike (one up anyway).

    The engine isn´t a powerhouse, it feels like low 30s hp give or take but is enough to get the job done. The frame is good for three or four times that. I found the sweet spot for cruising somewhere around 75mph, and it will do that dawn ´til dusk easily. By 90mph it is pretty much out of steam but then it is a single. The steering is quick, it is effortless through twisties, almost too much so, I think I prefer a slightly slower steering bike, on the Skorpion it was almost too easy.

    If I could find another I would be tempted to hold onto it, a very practical, fun and cheap to run bike.

    The grey one in the pics looks like a modded exhaust and front caliper. The standard Brembo caliper is fine.

    The supermono has always been a dream bike for me too! Gawd I love that thing. Being 6'4" I would look pretty funny on one, but I am getting older and not tryin' to bone everything in sight, so that's no longer a concern.

    I think I might just pick one (an MZ) up. I have a little place off the parkway in Little Switzerland, and this bike seems like just the thing. You don't really need much HP to have fun, just a bit of low end torque. It's really not a bad looking bike either.

    Here's our race bike. My son loved it as a starter bike, but he was ready to move up so we sold it to fund the next one. Then the little twirp says he wants to mountain bike instead! If I knew that, I'd still have the MZ. Last two pics from Road Atlanta

    These bikes have interested me for some time but I am concerned about finding any needed replacement parts. Anyone have comments on this?

    Everything you need is readily sourced. There is a small community of MZ suppliers around the US. A friend of mine has an MZ250 that came from Egypt and he sources parts from somewhere in Miami. The Skorpion is mostly Yamaha and standard parts anyway...that is brakes, sprockets etc are just normal stuff. I wouldn't worry about it a bit. Plus they never break!

    Well, if it's a two-into-one and he's drunk when he looks at it...

    I may need to re-think this. I really wanted a Tengai, but they're awfully difficult to find and the MZ's seem a little less expensive up front.
