The Yamaha DT50MX is the most common 50cc in the Yamaha DT series. Production started in 1978 and ended 1996. The moped is very common in Scandinavia where its leasing competitor was the Honda MT50. DT50MX is available in different colours, such as red-black, red-white, blue-yellow, black-purple and white-pink.
Boasting a 50cc engine and a five-speed sequential gearbox, it is still commonly used by 16-year olds as a means of getting on the road without having to resort to a scooter, a range of aftermarket parts are available including performance reeds, big bore kits, racing exhaausts and sprocket kits which enable the engine to develop more power and/or speed.
Honda’s NSR 50 is one of the most commonly raced bikes in Minibike club road racing. Though the NSR 50 is not street legal in the United States, safe and legal racing environments are available in many states, often found at kart racing tracks.
The NSR50 has a 49cc water-cooled, two-stroke engine, a manual clutch with six gears, and typically falls into class with other two-stroke 50cc road bikes such as the YSR50. Though, it is also commonly classed with up to 110cc four-stroke bikes.
The KTM X-Bow was developed by Austrian motorcycle manufacturer KTM, in partnership with Kiska Design, Audi, and Dallara. The X-Bow uses a turbocharged direct injected TFSI engine manufactured by Volkswagen Group, which produces 177 kilowatts (237 hp) at 5,500 rpm and 310 newton metres (230 lb·ft) of torque between 2,200 and 5,500 rpm.
Originally, KTM planned a production of 500 units per year, however, the company has increased production to 1,000 cars a year and has built a new plant near Graz due to high demand.
KTM X-Bow participated[3] in the Supersport category of the 2008 FIA GT4 Championship (#100 Catharina Felser, #101 Christopher Haase and Dennis Retera, by Reiter Engineering), taking a podium finish at Monza and the pole[5] in the wet qualifying session at Nogaro.
The FIA-homologated model KTM X-BOW „GT4“ is available for racing purposes.
