Js550 Vs Js550 Sx
can someone tell me what the difference is between the reg. JS550 and the JS550 SX?
i believe in 1990 they started with the SX. My ski is a 1989 JS 550.
i have the manual for the SX and it look the same when i match things up as far as looks go.
also my ski is stock except for R&D intake grate and a ocean pro ride plate.
i looking to do some light mods on a budget and also keep it relayable.
i am looking for lower to mid range power.
