Tank bag with straps

[grunn]

A bit of a noob question but that's because I am one-my first post here@tu*

I'm just about to buy a Blackbird and have a tank bag that I want to use with the bike. I notice that magnetic bags are what people use but this Oxford X30 lifetime bag I have has a strap base because my old bike had a plastic tank.

Does anyone have a clue if I'll be able to use it on the 'bird?

To fit it on the old bike I fitted the straps under the seat and looped them round the frame. I've never removed the seat of a 'bird and have no idea what lies under there thus the question.

There are two slots on the back of the tank, under seat front.
You also have a sub frame that the seat rests on.

Assume tank bag has a strap that goes round the bottom of the head stock?

Hope that helps and welcome to the bird nest.
