Notes
This bike was patterned as closely as possible after my "Blue" monoshock Norton with all
of the rare Dreer prototype bits that has been featured on several websites including
TheKneeSlider.Com, BikeExif.Com, PipeBurn.Com, and MotorcyclePictureDaily.Com. No
question it'll keep up with modern sportbikes in the twisties, and it's sure to draw a crowd
anywhere it goes.
