​
Microsprints started in Australia in the 1980s as a non-winged class of racing and have evolved to resemble their big brother, the Sprintcar closely.​
Microsprints are one of the largest divisions of speedway racing in the USA as they are affordable and provide a real-life sensation of driving and working on a full-size Sprintcar.​
Microsprints are an affordable division that allows younger drivers to develop skills before moving up the ranks of speedway racing. ​
What they lack in size, the Microsprints certainly make up with spectacular racing action at fast speeds.​
They are powered by a 2-stroke 270cc or 4-stroke 450cc single-cylinder bike engine running methanol fuel.​
Microsprints have plenty of appeal to the point where Speedway stars from higher divisions of the sports have sampled the class. ​
Microsprints will reach speeds of up to 130kph around 1/4 mile speedways.
