    Please feel free to add a picture of any other type of tank which hasn't been listed or shown. Also if I am wrong about years, capacity or colors feel free to point it out to me and I will correct.

    All R65 tanks from 1979 until 84.5.
    Basically that means any twin shock R45 and R65 tanks
    fit perfectly on any G/S ST or GS of the airhead variety.

    Same fitment issues as steel R100GS tank. It´ll form a gap at the base of the seat. Yes, it attaches via the same ´pocket´in the front of the tank used by all the other BMW tanks and the same bale at the back. That isn´t just a tool ¨tray¨ on top. It extends about 8¨all the way to the bottom of the tank and can fit quite a bit of stuff. Also, the capacity is 9.3 gallons, not the 8.9 listed. The steel R80G/S PD tank is 8.9.

    Sorry to hijak this thread. I picked this up from an Adv ad for my R80ST.

    Pic 1: note shape is like R80ST, not R80G/S, not R65

    [​IMG]


    Pic 2: note filler drain and vapor vent tubes. Also, welded on tabs that have no purpose on an ST or G/S

    [​IMG]


    Pic 3: note ST, R65 style filler but with PITA spring loaded flap like later GS. Also note original color - looks like G/S blue.

    You can use the mono lever tank from the non GS bike( RT RS STANDARD )
    IF and only IF you do this to the front mount and get the proper rear bracket and drill two holes in the back of the frame. It's not difficult, I have done it.

    Sorry, this picture was deleted when the mods were screwing around with picture posting awhile back. if anyone wants to see the mod, let me know

    yEAH, I doubt if non-US tanks would have US spec flaps etcetera. Actually, it looks like a California spec tank.
    my vote is for an ST tank, given the shape is the same and so is the gas cap.

    Just to complete a bit: I have this tank and it does not fit the G/S or GS without having to bend the bracket which hold the relais (at the rightside hand of the horizontal top frame tube.) Further it does limit the clearing of the front fork, they tend to hit the tank when close to steering stop.
    But, it is a great tank, looks the part and will fit both G/S and GS (the latter when using a G/S seat or after cutting the front flap of the seat.
    Here it is on my former GS (ignore the G/S side panel):[​IMG]
    O, and it will fit a /6 if the seat is shortened a few inches. It has become the hand-me-down tank, wandering along from airhead to airhead as my choice of bike changes through the years.

    That tank was meant for /7s and even the R90S.

    You've got your rear shock on upside down. That's the later shock that goes the other way round. I bet the aluminium collar catches your battery?
