Those 3 mods, usually net you enough extra power to not only go from a 15 to a 17t front sprocket, but also lower the rear by 5-10 tooth from stock as well, and still make enough power to do 70-75 mph.

The Hawk and all of the bikes like it are aerodynamically challenged. It's not just the fact that they have worse aerodynamics than a house, but that they have a lot of frontal area. A Vader 150 is a much smaller bike in terms of said frontal area, and big frontal area + terrible coefficient of drag = no speed.

A Hawk won't touch 80mph. Not without serious work, and even that is going to come down to the height and weight of the rider on the bike. Most Hawks and Hawk-like bikes top out at 68-70mph, tops - with said mods on the carbureted version being required to achieve it. The DLX makes about the same power as a cab hawk with an exhaust and proper jetting.
