This /5 or newer Heinrich was interesting for two reasons: One, the indent in the tunnel area, and Two, the ID tag on the bottom. This tank was made by Werner Reinschluessel, who took over tank production in 1981from Karl Heinrich.

ID tag on lower left- Werner Reinschluessel (RW on the tag) made these tanks from 1981 to 1984, when he transferred the rights over to Jeckel. Code 208 indicates that this tank is made for R80 G/S, and holds 40 liters. The number 743 is the serial number.

Go ahead and add the R100GSPD tank to the list - it fits nicely.

[wirewrkr]

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.

Note-tool tray on top of tank

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.

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):
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?

You mean my tank or in general? The tag on mine has a code 208. Which in One Less Harley's post is indicated as for the G/S.
Anyway, let's not go totally off topic here, I just tried to give some more info on the tank.

[acap650]

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




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




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.



Clueless in Pittsburgh

[wirewrkr]

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

It looks like a later r80 GS basic tank to me, they had the tank which ll\ooked like the G/S tank but a locking cap and being a later model probably the venting (I'm guessing on that).

No you're not hijacking the thread that's what it's here for, getting info on tanks.

Thanks and I thought of that possibility. The R80GS Basic was not imported here and there is still what looks like OEM G/S blue under the repaint. I guess anything is possible.
