I believe most systems, if not all, are run through the computer, so you would need the sensors and related parts, plus the pump/pumps, plumbing, and harness'. Probably at least a couple thousand dollars. May just be better off riding this one for awhile and buy a bike that already has it. I'm no expert, so I could be wrong. May also be able to buy a salvage bike that has everything you can install on your, plus have other spare parts.
