Boat Rap (Japan), whose name I can’t explain, have a great backlog of custom bikes they have constructed based on popular Kawasaki, Yamaha, Suzuki, Honda, Triumph and even Harley Davidsons. Custom jobs include Choppers, Bobbers, Scramblers and one or 2 tidy little Cafe Racers. Although Cafe Racers aren’t their specialty they know theeir stuff and are great for inspiration…or just eye candy. Their website is mostly Japanese but you don’t have to be able to read it to appreciate their work.
The also sell a range of aftermarket parts and accessories to complete your own custom project.
