The Viper was an entry level race/dirt bike, the Joker was an entry level street/ramp bike and the 3 years difference in manufacture year means that the Joker was lovingly crafted from decomissioned ship anchors. Personally, the 95 Viper is the nicer looking of the 2 and would make a cool mid school rider, also it wont give you a hernia when you attempt to make it leave the ground .
