Those look like "lifestyle brand" engines, Ed.These are hand built one off bikes....they've been written up before. Customer spec from a base design, upgrade where you desire starting with a high level of standard.
The design brief is performance, so everything is lightweight materials and top level suspension/brakes etc.
They actually are not all that heavy and reports are they handle very good and make big power (torque)....but you have to be rich and want a bike no one else in the world has. These appear to be the original spec samples.
I don't think $11,000 for the engine is even close. Lee had $10,000 in the Green Monster engine. A stock Harley motor from their Screamin Eagle program is $7,500 or so.[/
You could be right, but the $11000 included the supercharger. I'm not familiar with the green monster engine and all it included.
