I’m pretty sure that Brad is correct. The RM1 isn’t allowed because of its gearbox which when it all comes down to it, it’s technically a shifter (it would be pretty funny to see it in a shifter race!) But I would advise against the RM1 due to its odd axle/engine setup. The axle actually goes straight through the gearbox and probably requires a specialty axle for just that kart. It seems like it would be a lot more of a hassle to change axles and especially extract a bent axle, and a bent axle could do a lot more damage to that gearbox than it’s worth. My advice would be to set up your Rotax on another chassis and not worry about that gearbox or if your kart’s legal. I bet you can build one for about the same price as an RM1.
