CT Scuderia Watch Check Flag CS10134. Back in the earlier days of racing, the tracks were dirt roads. Dust and dirt would kick into the air, making it difficult to see, especially when moving at high speeds. The contrasting black and white checkered flag was easy to spot and therefore made the perfect finish line flag. Check Flag is part of the Cafe Racer world where racing attitude, history and style become a unique mix for all motorcycle drivers.
