a Tank mount, motorcycle bag that comes as you see pictured in the listing and noted above.     I looked around for a model name, but they are only marked on the outside with Rapid Transit.   This is in great used condition, so please review all of the pictures to see their true condition.    The bag measures approx 18" across, the height is different from end to end with the low end measuring around 6" tall and the tall end measuring 9" tall.   The thickness is 10" across.    The bottom has some bungee type straps with hooks on them.
