I will have to search for some other picutres. Tank is a Heinrich, or at least whomever was making them under that name in the late 80's.
It is 41 litres. That is a custom vinyl cover on the tank, which has never been painted (just primer) had a buddy who used to make tank covers for the airheads and I twisted his arm to make this one for the big tank. He only ever made one!
The rear top box looks big, but it is actually cut out in the middle on the bottom as it sits down on the subframe and thus fits over the rear fender..
