If your TB only goes 40 something is major wrong with it.Ours is HPD modded and it will hang with anythingout there.

 

50mph sounds about right.....stock that is.

 

Is there any blasters with a automatic?

 

not one you can buy from a dealer

 

For a new rider I would go with a trailblazer, if your experienced and want pure speed for a small engine then yes the others would be better, but unless you are a true racer you'll be happier int he end with a trailblazer
