I think the standard tank is 16.5 liters. So you are not gaining much with this alternative.

I have several restored bikes along with a 2006 Goldwing with a sidecar. My wife has a 2019 Suzuki DR 650 for on and off road.

I've seen many D model 650s with B/C/F tanks, and vice versa, so I think mounting is no issue.

I know Rick/bensherb on the 650info forum has a D tank on his B model.
I will ask him...

Yes, Rick confirms it's a straight swap, D tank on the B/C/F models or their tank on a D model.

Cool bike!
it’s the same tank I have, so my tank is D tank then.

it’s a F tank I must consider then to gain 2,8l?

example?

Side covers for a B will not fit a D. Different mount holes. Gas tanks are interchangeable.

You can use a B, C or F model tank, they are the same size.
The tank badges are different through the years, 1977 & '78 having recessed badges and all caps KAWASAKI, and '79 and later not recessed and Kawasaki spelt with lower case letters too.
