 | When are you ever going to need to go this fast? You plan on riding it on the street?

 | Um, the motor does not have enough power to propel the bike that fast. Say you get a smaller rear sprocket, the speed will go up but torque will go down. Even in stock geared bikes the bikes are not able to reach their theoretical top speed. You can a tooth or two larger on the front and down 3 teeth in the rear. However you will not even have the power to get going even in first and still would not reach 80mph.

| if you are wanting 80 seriously, you might need bore+stroke+and alot of other mods just to take off, you probably will have to literally have someone pull you on a 4 wheeler or something just to take off in first though.

| Most 450f's don't even like to go 80. Usually they top out somewhere between 80-90mph and they rock 50hp.

| i wouldnt waste the money doing all that to the engine, buy a newer bigger bike and it will go that fast. or you can throw alot of money in it and ungodly amount of engine work. i dont really see the point in it.

| Like I am saying, stock 450f's barely can do that. Granted there are plenty of 100mph bikes out there.
