Not a combination you ever see mentioned, would it work ??

How long is the Fastback tank compared to an (850) Interstate tank.

More bikes and projects than you can shake a stick at but they should be done in two shakes of a lamb's tail.

Hmmm, I've got 520 mm there with an Interstate seat.
So this is not going to work.

Thanks for the measurements Les, saves me throwing $$ at something that isn't easily done.

I cut off the ears along the weld lines from an Interstate seat pan and bolted them to a new position to suit the shorter Interpol tank which is the Fastback LR tank but with a cutout for a radio. I could have done the same with a Roadster seat but the curve does not lend itself to moving.

I pondered something like that.
But the recently obtained Interstate seat seems to be brand new - and has a plastic (?) base.
Not easily altered ?
And at this stage, I have a working Interstate tank/seat/sidecovers, so a bird in the hand etc.
Roadster seat has had rust weevils in the base, just still hanging together, not to be trifled with.
I'll think on it some more.

Fasterstate eh
Good one - but maybe it was never meant to be. ?

btw, has anyone noticed that all these new seats available are not quite the same as the seats of old.
They have a panel and a seam running midway towards the back that the old seats didn't have.
Not a biggie, but they are not quite the same..
