I have only hit 5th gear in the sand and I hit about 68-69mph and that is up a slight hill. I think that is pretty good considering the sand. On the road 75mph sounds about right.

But you also have to look at gearing. You can have all the power you want but unless you change the sprockets its not going to go any faster.

exactly, top speed is determined by rpm's and gearing not exhaust or pistons etc.

Weight factors in too. I found a major decrease in top end speed after install HD rears.
