My '93 R100GSPD. Not as BMW intended. But subtly improved bit by bit over time. The Wedgetail iginition system is my favourite modification. Two very loud airhorns are the most useful. Acewell dash, Trucklite LED headlight, Odyssey battery (in correct sized box), and Denali spots are great. The gearbox is a 1996 model, replaced under warranty at 30k by the BMW dealer after the missing circlip caused the original to fail. It's on about 130k miles. Frame has been powder coated.
