this is also true! 'c' being the common thing amongst all the 'c' models is the 'lesser' equipment-most obvious being the narrow fenders. seems we are splitting the atom again! this doesn't mean the narrow fender means its a 'c' model. example.....narrow and wide fender motorbikes-equipped. ba107=wide fender version, b107=narrow fender version. not an exact 'science'! also a narrow fender 'd' model-first year w/ diamond frame. start with frame and 'build' out (equip)from there!
