Looking for my next kart. I am stuck on 2 options. Prices are both close. One is a rotax rm1 with dd2. I’ve read some things about the rm chassis and how its not the best out there. Kart is clean and good cond. The other is a tibi kart with yamaha shifter. Never heard of tibi kart but from a little research found they are built good. Anyone have any knowledge of a tibi kart? I can race either in clubs here so that’s nit a issue. Just curious for some opinions to help me out. Thanks guys!
