A big production motorcycle engine would
be 140 cubic inches, this one is 410!

I just want to ride it once!!!!!



The Gunbus 410 cubic inch (6728cc's) 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. 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.
