Harley-Davidson did try a venture into a "sporting machine", long before the current day Buell's.
In 1977 the XLCR was pen'd and produced by none other than "Wille G. Davidson"! It was a pure cafe racer, quarter fairing, Norton style "fastback" rear section, superbike bars (no not the lower, "Clubman bars" of the period, used by the European's).
It used the "iron 1000cc Sporster motor" and was a very good looking and decent handling machine. For H-D it was "way to racey" and the faithful stayed away in droves so it was only sold in 1977 & 1978. Too bad, if it could have continued, maybe the current Buell's would have been using a more modern "VR1000" style motor (60 degree V-twin, water-cooled, double overhead cam, ect.), it could have made H-D a real Superbike contender!
I'm having real trouble finding a picture but hopefully I can score one soon!!
