Check this out. This is one of the best looking custom 3 wheeled and ATV bikes. Both of these bikes have been displayed recently at Tokyo Auto Salon.
Below is a 3 wheeled bike with custom body panel to look like a Ferrari F1. It is even fitted with the real decals as well as the gold rims for the rear. The rear spoiler is a reminiscence of the real thing but only smaller.

Next is the ATV with a Lamborghini Murcielago look. Now this is interesting. Next to the ATV is the real deal. The ATV is customized perfectly to match with the real Lambo but only smaller. You got to hand it to the Japanese. It is even sold out during the event. I wonder how much do they sold that ATV Lambo. It's sure is gonna be good collectors item.
