I max mine out too but only for very short bursts. Like climbing a big hill I rev it out really good but only for like 15 seconds at the most. If I think it will require longer then I play with the throttle, revving it up and down about 500-1000 rpm at the top of the rpm range.

 

I dont see the point of an 80 plus mph quad. They are designed for trails and some mx. My Z is plenty fast, besides I feel it will take ANY quad on trails anytime. So top end doesnt matter to me.

 

I wanted to gear a tooth higher on my Z last week, but the more I think about it I don't need extra speed either.

 

an 80+ MPH quad is good for baja racing, plus in somplaes there are those long winding trails where you can crank it up
