The C5 classic model has the sprung solo saddle / with or without a separate pillion pad , It also comes with a headlamp peak as standard.
It has different rocker boxes, they are more smooth and rounded, this model also has slightly wider outer cases, giving a more bulbous appearance and NO kickstarter - the hole in the [different] right hand casing has not been machined out.
It also comes with smaller (18") wheels. The side toolboxes are the familiar triangular shapes. it also comes with an extra lockable left side panel that's oval in shape - to assist partially obscure the fuel injection unit.
I saw the black one today - beautiful . shame the gear lever is on the opposite side to the original classic
oops forgot the obvious difference - the classic's barrel is painted black, not silver
