Motorsport in all forms has been around since the early 20th centry, with profiles such as Steve Mcqueen, James Dean, Guy Martin etc. Although motorsport is fun in its form, due to the expense the 2 wheelers has dominated the scene for entry levels to veterans. If we take a look into road racing as a sport, its a high cost 2wheeler sport on unique tracks with top speeds in the premier class exceeding 300km/h.
There used to be an accessable class for youths and amateur riders – Moto 3, simple 125cc 2-stroke bikes. The regulation changed in the early 21st centry to favour a new 4-stroke motor that could easily outrun the 2strokes with its instant torque and larger CCs. The class suddenly got expensive, noisy and out of reach for new riders.
This resulting in a slow movement dueconstraints from noice requirements and high cost, this limiting timeslots for practicing & racing to early afternoons and a few weekends per year.
Mattr together with SVEMO (Swedish motorcycle racing assosiacion) are developing a new class to minimize cost, noise and maximizing riding hours for all participants.
”The working name of the class is Moto3E, introducing our bike Mattroid”
