What's the ugliest bike you've ever ridden?

I once had a '70 Honda CL 450 a guy ran without oil. The engine locked up which then sheared off the studs holding the rear sprocket on. It had set behind his barn for a number of years in the weather, the seat cover was rotten away, rust everywhere, chain locked up, plastic tach and speedo lens hazed over and at some time had a secondhand paint job applied with either a very coarse brush or corn cob. I bashed the pistons out of the block with a sledge hammer and got the engine running, welded up the rear sprocket and tied a car battery onto the luggage rack. It ran well, but in typical 450 fashion, vibrated like a jackhammer.
