The good thing with parts customization is that there is not really a superior way to go. Every part, from body to handlebars to shocks, affects different stats with a give-and-take - for instance, one part will give you better air control so you can steer during jumps, but it will reduce your ground steering. Playing around with these parts is fun because you can really feel the difference: our first attempt at specialization saw us focusing on parts that maximized air control over everything else, and we were practically like an airplane during jumps. Later, we focused on pure acceleration and created a virtual ground rocket that was a bitch to turn. http://naildbiter.com/DNNzX
