An old boss of mine was an aircraft engineer - told me radial engines were round for one very good reason - easier to roll to the dump!!!

Maybe not great in planes, but those bikes look wicked!!!
I like the two different mounting considerations - and consider the Jesse James style more condusive to turbo-charging...!

Tonight I was watching a show about Bike Week at Sturgis and a custom builder had a 7 cylinder radial custom built bike that looked just like the one posted on the bottom.He said that he is going to build a dozen for production.He also used Harley V-Rod bars on the proto.

Hey Joe, a typical 7 cly radial like this one without supercharging or turbos put out around 350 to 400 hp. Don't mean to pop anyones buble, but this type of engine has been around for years because of its reliability. As a side bar, most of our WWII aircraft were powered by radial engines. Today most of your bigger crop dusters (you really want an engine that reliable in these rides) use radials.
