The Gunbus 410 cubic inch V-Twin
motorcycle. 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.
