Switzerland is usually viewed as a country of reliable and conservative people and companies, but there are quite a few who break the mould: MB&F (watches) is one and Grüter + Gut (motorbikes) is another.
Grüter + Gut stared in Ballwil/Switzerland in 1983 selling BMW and Moto Guzzi motor bikes but soon started modifying them . . . radically modifying them and the GG-Quad is their latest toy.
With prices starting around $50,000 the high-tech Quads are not cheap, but they sure look like fun!
