Fuel Tank identification

[paulf]

Hard ask but just wondering if any one can possible identify this tank for me please.
I'm confident it's an older Suzuki but can't seem to be able to identify model/year...

Look from the bottom , notice no fuel gauge hole so that might be telling.

Try here lots of pics but its not necessarily every pic of every bike in every market.

It does have the same outline as an early to mid eighties cap. A rounded off rectangle affair.

the cap it uses was not superseded and is 44200-49810
plugged into partszilla it shows 55 models used this cap at least in NA
CSML is european if you try there results may vary.

Thank you gents, will have a look. The emblem is a giveaway for an older model but the grooves on the side for gripping with the keens look a bit too sporty which should eliminate GS models
