Hi, I would like to hear what you know about moving from rental karts to rotax senior. I drove rotax a few time. Obviously the speed difference and a lot of throttle control involved, but can you tell me anything else to watch out for?
Stay smooth like with rental karts, and work hard on your fitness. A really good rental kart driving style works well in rotax, so if you are good in rentals you'll be fine. good luck
