Sorry to raise an old post, but came along this thread while searching for information on the RM-1.
I am currently competing in a DD2 class in South Africa driving an RM1. These karts are really cheap a 1/4 of the price of the newer age karts. So while i am slower than the rest i still have great fun participating.
However, perhaps someone on this forum knows the correct seat positioning and kart scaling % i can dial in. I’ve searched all over the web but cant seem to find any info..Basically looking to get an optimum kart setup to try close the gap a little.
