The Extreme Tantrum 50cc looks identical to the Kasea. Or they both moreless look like a older 400ex. lol We had a Extreme Tantrum and the thing flat out screamed. It was made by Aeon, which also makes the Polaris Outlaw/Predator 50/90cc quads. Anytime I needed a part ASAP, we just went to the local Polaris dealer.
