Gunbus 410 cubic inch
« on: September 03, 2008, 04:18:27 AM »

The Gunbus 410 cubic inch V-Twin motorcycle is complete.
The monster engine placed in a motorcycle frame of comparable size looked impossible and many who saw the photos were sceptical of the bike ever being finished but I guess, Clemens F. Leonhardt is one of those persistent guys who ignores the naysayers and keeps at his work.
The fuel injected, 45 degree 6728 cc / 410 cubic inch V-Twin runs through a 3 speed transmission with reverse and actually looks pretty good in its finished state compared to the initial photos, in fact, everything looks good.
It puts out 523 foot pounds of torque. Seat height is 31.5 inches and overall length is 136 inches.
It is a little heavy at 1433 pounds so high speed corner carving might be an issue and there aren't any photos of the big bike on the road so I guess we'll have to wait for the road test. That is if someone can actually road test this monster.
This is actually going to go into limited series production and a sidecar will be available as well which might help with balance when waiting at a light. I don't even want to think about a driveway tip over. I think this is great! Now, where's the video?
I think the thing I most like about motorcycling is the speed at which my brain must process information at to avoid the numb skulls who are eating pies, playing the ukulele, applying make-up etc in the comfort of their airconditioned armchairs as they make random attempts to kill me!!!!!!!

Assuming the young lady posing in the photos is a midget, how much fuel can you cram in that long but slender gas tank?

OMFG!

How big is too big???

That thing has more c.i. than most trucks!!
I bet just the rear tire costs more than my entire '79 650 build!!
 
And NO CHAIN GUARD????
With that much torque, I'd be FREAKED out about snapping the chain!

Do you suppose it's as high maintenance as the blonde?


One of the sites said the tires are from a 767.  :o

Guy was going to use aircraft tires, but some tire company found out what he was up to and built custom tires for him. If I'm not mistaken, the tire company is pasted all over the tires. But now that I've clicked reply I can't see them.  ::)
