Watch Formula M racing action at Zwartkops!Here's what he had to say...Formula M racing is a racing series that uses single-seater race cars powered by motorcycle engines. The club started in 1963 originally called the Micro Midgets. We then changed our name to the South African Formula M Racing Club. Video: Formula 1 action at the Zwartkops racewayThe main objective of the club is to promote motorsport to youngsters. We have four classes in the club: CLASS DClass D racing is the development class for kids aged from 8 – 13-years-old.The car is powered by a 125cc motorcycle (two stroke) or a 250cc (four stroke). The engine is mated to a six-speed transmission and cars can reach speeds of up to 120 km/h. SET TO COMPETE IN 2014The motor must remain standard and no modifications are allowed. At this stage we are training youngsters and do not race them. We are positive that we will be racing in the 2014 season. CLASS C Primarily this class is for high-school teens aged 13-years-old and older. The cars used in this class run on racing slick tyres and are powered by a 400cc motorcycle engine mated to six-speed transmission. Top speed is in the region of 180km/h. This is a controlled class and no modifications are allowed. CLASS B This is the main class in Formula M with driver ages from 15-years-old and older. The cars are powered by a 600cc motorcycle engine and can reach speeds of 200km/h.'TOP SPEEDS CAN BE AS HIGH AS 290KM/H' CLASS AHere we have the big bangers of formula M and the cars are powered by fast motorcycle engines with the Hyabusha motors being the popular choice. Top speeds can be as high as 290km/h depending on vehicle setup and driver ability.
