Does anyone know if anyone in Colorado carries the RM1? Is this a legal kart in the CSC or any of the local tracks? If so, what class does it run in?
I agree. What are the cons to direct drive compared to chain drive? You would figure that obviously #1, no chain to break. However, is there more parasitic loss from it being shaft driven? (if negligible, who cares really….less maintainance). Who makes the chassis? The 2 speed setup seems like a great compromise between the performance of a shifter, and the low cost of running a touch-and-go setup.
Chuck Denison from Cheyenne has/had one, I don’t think he made any races this season. I’m not even sure he still has it. Last year he ran it a few times in the Tag class, Last year the tags were not split up so I’m not sure where it would run now.
During the testing of TAG engines last winter with SKUSA and TAGUSA this question was brought up, but the RM1 does not conform to the basics of the class, mainly the two speed gear box is the problem. The answer to the question is no I don’t believe it will be allowed.
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.
Larry,
I have Check’s e-mail if you want it.
I ran with Chuck last year 2 or 3 times. he was faster on the straights but I closed on him in the corners.
I would be careful about getting one. There is no one that has one in this area to race against and it may not qualify for a TAG class.
