Thanks all for the info on strap retaining nut threads. I'll now run a 5/16 BSC die down both of the tank stud threads.....chrome plating had been left on the studs.

I know this is an old thread and judging by the date, it's obviously something that doesn't get talked about very often. However, I was surprised to read about the importance of fitting a tank stiffening strap and the likely consequences of not doing so...so thought it might be worth resurrecting for some of the newer A7/A10 owners like myself.

Anyway, the strap on my A7SS is missing and so far, I have bought three from different sources. The first two didn't fit (distance between holes too short) so they went back. I've now just received another from a well known dealer and whilst it fits, it's not a flat bar I was expecting to see as shown in the parts book (not in the greatest of condition either!) So I'm wondering if anyone knows what bike this was intended for?
Anyway, given what has been said on this topic I think I'll just paint it and fit it...better than riding around without one.

Judging from what dealers are selling GB, that's probably the best way to go!

I don't have anything at home that I could use but I'll pick something up at the next autojumble visit.

B&Q would probably have something suitable. Doesn't need the offset; at least not on my Plunger model.

The tank (original I think) on my A7 plunger doesn't have the lugs. Possibly due to the A7 tank being smaller than the A10.  *dunno*

Tommo, they usually aren't a flat bar and have the two double sets as you show.

That's interesting Trev...I was just going by what's shown in the parts book...not that they're always correct!

I assume that your bike is a swinging arm, Tommo?
These straps are double set to clear the centre rubber buffer bracket.
Oddly it doesn't foul on every frame/tank combination.

Yes Trev, my A7 is a swinging arm.
When I fitted the tank strap I have (with double set) I did notice the rubber buffer bracket that you mention and thought perhaps that's why the set is there, but then realised that a flat strap would have cleared it anyway  *conf*

anyone know why there are upper and lower antiroll rubber positions on the swinging arm frame
----------------------------------------------------------------------------

To answer the question even tho its an old thread. The lower holes are not for rubbers but were used for the sidecar mount

Never seen a sidecar mount there.
