The XTC sounds very quite because it is a four stroke, unlike a noisy two stroke. The handling is up there with a mito and it is more comfatable to ride than an RS. There is endless things you can do to tune the engine. Because it has a 150cc engine in it. The nomal speed is 75mph. Much slower than other 125´s because it is a four stroke, but wot it lacks power it makes up in looks and sex appeal!
