I had a Grinnal Scorpion with a 167 bhp engine. It was lethal when accelerating hard, there was no warning and the back end would fly out in a most uncontrollable way. I know 2 people who have written them off by losing them this way. If you want a powerful 3 wheeler then i would want traction control. My god it was fun though

If anyone is not away of the scorpion here is a video. https://www.youtube.com/watch?v=UwwEJhuCmjE&feature=share
