i recently bought the UFO unit off ebay for my '03 954rr and its awesome...its a HUGE pain in the *** getting the stock tail light apart...its glued together and the clear plastic chips and cracks easily...luckly no serious problems...and the unit is very good quality...yes expensive but i have been riding many yrs in the north east and seen many bikes and never anything like this...the programs are awesome and so simple to change...wicked cool product...aside from splitting the tail light i highly recomend it...i know kids that will jiz in their pants riding behind me watching that thing...my only concern is them being distracted and wrecking from watchign my damn tail light
