Does anyone know of any championships or classes - whether in the UK or elsewhere - where Rotax Seniors and X30 run together on an equal basis? And in particular what are the respective weight limits?
We're been running an open 2-stroke class in our Inter-Service Championships for a number of years, but have not really had any X30s seriously racing until last year, and the question of suitable weights has inevitably risen. Recognising that it's never going to be an entirely level playing field because the different engines will perform differently on different circuits, it would still be interesting to know what other competitions have come up with to try to balance things out.
At the moment we're running a mixture of Evos and older Rotaxes at 162kgs, and X30s at 164kgs. Tyres were Mojo D2 in 2018.
Any thoughts?
