The GP-0 160 is the little cousin of the 190.  Putting out around 15 horsepower it is definitely at the top of it's class.  A good platform for adult riders to train as well as youth riders who are ready to step up to a faster bike.  The 160 is well-capable machine that has slightly less maintenance than the 190 but who are we kidding, these things barely need maintenance to begin with!
