The Supersport 300 class features motorcycles from around the world that are designed to be competitive with one another through various modifications. The FIM officials had likely imagined the balance regulations to be simpler. This was partly because, for example, the Kawasaki Ninja 400 wasn’t available until shortly before the first World Championship race. The World Championship technicians had very limited time for testing. There was no balance at the start of the World Championship season.
The IDM Supersport 300 adheres as closely as possible to the FIM regulations. The goal is to enable young German riders to compete in the World Championship with minimal effort, and conversely, to allow a World Championship rider to compete in the IDM without any problems. However, the imbalance among the motorcycles has hardly been noticeable so far, as only two Kawasaki Ninja 300s were used alongside KTM, Honda, and Yamaha.
However, the FIM has now revised the regulations once again with new technical rules. According to IDM Technical Director Karsten Bartschat, this now ensures a relative balance between the manufacturers.
The changes made so far involve allowing for increased air intake on Honda and Yamaha bikes. This boosts performance. The RPM limits for all brands have been adjusted several times, as have the minimum weights. Everything should be up to the latest technical standards for the upcoming IDM round from July 6–8, 2018, in Zolder.
