Just like a motorbike except on most quads there are thumb throttles instead of twist throttles.
The throttle body on a stock mustang should not hurt the performance. You can always upgrade to a better performing throttle body. Unless you plan on changing things like air intake, exhaust, headers, and things of that sort you should be just fine with the stock throttle body. They are already designed for the most efficiency and power ratios.
