Salutations! Very new to the community I found a near by dirt track. Im 250lbs and 6' (currently working on losing weight) I was looking to spend around +-200 bucks on somthing to mess around with. The bike Im currently looking to buy is the Diamondback Viper or the Viper X (Can't find one at a shop might have to buy online and put it together ). Any Suggestions?
