“Gunbus 410 Cubic Inch V-Twin Motorcycle”

This one is well and truly OTT probably too big to use in any practical way but who can deny that it would be the perfect machine for those who are grossly deficient in the genital endowment department?
That said, there is part of me that loves examples of outrageous folly especially if they can demonstrate that the machine can be ridden… Interesting too that they should display the machine with a beautiful girl in the saddle rather than the beefy sort of bloke who would be capable of actually riding the bike.
Cheers Comrades 😀

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 skeptical 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.

    Looks more like a motorcycle than a “Boss Hoss” with the U. S. automotive V8 in it!

    Nice bike! Even still I want to build a twin in line Shovel Head. 100 0/0 H.D.!!!!!!
