Right. Top speed is dictated by final drive ratio and engine rpm. Increasing engine rpm will increase top speed a little, changing gear ratios (via chain conversion) will have a slightly greater effect. Though, by the time you geared it high enough to reach 160mph, it would accelerate pretty poorly without greatly increasing horsepower. It might go really fast, but it'd take a while to get there. By the time you built an xb to *go* fast as well as *accelerate* fast, you'll be many thousands of dollars into a build. Many, many thousands. Like, enough thousands to buy a second bike and insure it.
If you want to go 160+ mph, you bought the wrong bike. Take the $6k +/- you'd spend building the snot out of the Buell and buy yourself a nice used liter bike to kill yourself on. Gear a modern liter bike so it accelerates like a 600 (still faster than an xb9 after it winds up) and you've got a solid 160+ mph bike after $250 in mods.
