I am 5'10 and 150 lbs. I ride in my woods mostly but there are very tough trails. Alot of rocks and other obstacles. Also there is a very large hill to climb. Its pretty steep and covered with rocks. I need a kart that can take a serious beeting cuz i drive these karts pretty hard. I have been through all the Manco karts and they have all broken on me from my riding. I cant have a kart with an unrelieable transmission (especially reverse), its gotta be solid. Also the suspension and steering has to be well designed and solid. Those were the main things i was having a problem with. If anyone can help me find the right kart, it would be much appreciated. BTW i am looking for a 2 seeter. Thanks.
