Dose anyone know how fast this quad goes at top speed?

 

First, welcome to your first post on the forums !!, To answer your question, with a totally stock motor, and the stock 23" tires, you should be looking at 55mph for a top speed, not bad for a 350 cc full time 4wd quad. That may vary a few mph depending on the condition of your quad, your elevation, and any other factors that would affect engine performance.
