Engine:
flathead 500, slow but with massive flywheels and lots of torque, a child could start it,,,i do! Lucas magneto for sparks, mighty hot at kicking rpm, helps starting. I've had mine rebuilt and recommend anyone with an old mag Brit to do the same, best thing you'll ever do to improve starting ease.
Suspension:
none on rear girder on front, one could safely say 'minimal'. it does have a friction, adjustable damper on the front; thank goodness!
Wheels & Tires:
got them, ya. traditional old Brit, 19inch both ends. The brakes work surprisingly well but one must always apply both when street riding to get the best effect, as one should on any bike really.
Body:
olive drab with a brush just like the Brit army did.
