When you get bored with regular motorcycles....

Sorry this probably has already been posted but I thought it was pretty cool. I think it's just a glorified engine stand, but think of riding something like that!

That would vibrate like crazy.

Or this.... Different style of mounting the engine.

I wonder how heavy they are :confused:

[nosliw]

i bet that thing tears ***

any vids of it running?

those look like the airplane engines they use to use a long time ago. horizontally opposed but I dont think they vibrate that bad or else they wouldnt have used them on planes

Yep, they are radial aircraft engines from http://www.rotecradialengines.com/ . 110 horse 7 cylinder and 150 horse 9 cylinder engines from Austrailia. They have used them on a few airplanes listed on the site. The engines look huge sittin on the bike, but are actually pretty small in the world of radial aircraft engines.

That would be cool if there was a place for your feet.

you dont have to be a genius to figure out how it could happen accidently.

Radial engines shake like hell. Atleast the old ones did. Only got a couple hours in a twin engine Grumman goose with original spec radials. It shook like hell when those puppys were cranking

But them puppy's shure sound good!:D Can't beat the sound of a radial. But I had a P-51D Mustang do a low-level flyby right above me and those sound pretty good too!

[ak_stick]

They have a very distinct sound, the best had to be the B-17G that I saw though. A wall of noise is the best way to describe it.

motorcycle V-twin engines were/are actually derived from airplane engines. the motorcycle V-twin is just 2 of the 45 degree opposed cylinders taken out of the airplane engine.:eek2:

lol, watching that moving engine diagram makes me feel all tingly:D
