Different slant on a Guzzi sidehack

[Seagondollar]

Somebody posted this in Facebook and I don't know if it's been shown here, but I'd like to know who's idea it is.  There's bound to be oiling challenges and I suspect it's a dry sump but don't know.

wow, lots of engineering put into that.. I'm guessing European?

I'm trying to figure out why the engine has been put in at that odd angle.

I see that if the engine were installed normally the cylinders would interfere with the frame rails, but it looks to me like it would be easier to move the frame rail a bit (at this stage) rather than deal with potential problems due to horizontal and vertical cylinders?

But it's not my bike, so ....

Moves the COG to the left a bit, probably worth it for racing....oiling shouldn't be a problem..looks like oil tank behind the trans...like the OP said..dry sump.....Ducati and Suzuki do a similar set up.only longitudinally..... .maybe some mods for scavenging...looks like fun though....

  I am thinking it is from the land of Oz, and it might be a racer but I would expect more radical weight shift to the left for racing.  Oz sidecar racers are radical indeed. I think it bis for road use, primarily on the left side of the road.

Seems to provide a nice straight drive line. I imagine changing the starter would be a bit of a challenge.

Nicely done..

That setup is very Interesting!


Itsa time to remake a movie!

I wonder where the pilot goes?

Either way, he had better have a grill over the carb!

It's a kneeler -- the pilot kneels on two kneeboards astride the motorcycle part. The passenger -- aka the monkey -- climbs all over the platform and the rear of the bike during the race. Google "sidecar kneeler" to see other examples.

It's apparently still under construction and this is a progress report. Note that the valve covers are missing some screws.

Are those two master cylinders sitting below where the platform will go?

It does look very nicely built.

P.S. That movie, "The Sidehackers," is available on Amazon Prime! Hoo boy!

As a guess, so that if it flips on its side in a crash, it has a chance of being repaired quickly and run in the next race.  The engine is well protected in this design.

A clever design. The clip-ons may be wishful thinking, though...leverage and all that.

No, clip-ons are standard operating procedure for these bikes. Here's another Guzzi example, found by googling "kneeler sidecar":

I suppose with the right (custom) geometry they work fine.

I imagine they've worked out the steering on racers, but both of the outfits I rode required wide handlebars. Even the BMW /2 with the two position Earles fork was a handful...it pulled left under acceleration and right under braking (unless you have really well adjusted sidecar brakes). Maybe those riders are just beasts...

Well, it is a racer.

I had a R60/2 with an Earles-type fork and a Spirit Eagle sidecar that was nicely set up, requiring no great effort, though I did mount sidecar handlebars after a while to make it even easier. I think the light weight of the sidecar, at 140 pounds plus passenger, was important. The guy I got it from used standard handlebars and had the front axle in the non-sidecar position; even then it worked pretty well.

Not only can you stream it, the Mystery Science 3000 version is available.

That looks like a very nice build and well thought out. To me it looks something like a 1100 engine based solely on the black wrinkle engine paint, a six speed gearbox and the final drive is a mystery to me, anybody recognize it? General finish looks really nice, would love to read a build thread on that one!
