I have a 1969 tr25w and the parts book calls for a ssm 2001/02 speedo. The bike is not a ss model and has the tach blanked off on the motor. The speedo is missing but a single rubber gauge mount is on the top Tree. The rubber mount is for the larger gauges.
My question is: is there another speedo for this model or did someone change the mount to accommodate the bigger speedo? Or did it only come with a tach?
Completely unconnected. "SSM" is the Smiths prefix for all speedo. part numbers; "RSM" is the prefix for all tachos.
If you enter "smiths ssm 2001/02" into your preferred internet search engine, it should return links to pictures of what you're looking for. It's a 0-100 speedo., appears to be a smaller diameter than speedos. and tachos. on bigger bikes and have attached mounting brackets.

The Smiths tacho. number starting with a "3" indicates the same size as found on bigger bikes, and the parts book shows it and the mount are larger than the speedo. and its mount.
Or, as you suggest, a p.o. could've tried one of the more-common larger-diameter speedos.

What does the parts book show? In '69, I doubt there were many countries where a road bike could've been sold new without a speedo.?
Thanks for all the info. I have located a small grey face speedo 2001/02. I just wanted to make sure I was going to purchase the correct item and there wasn't an alternative. The parts book shows both tach and speedo. I do not have the double gauge mount. The mount that is on the bike is for the larger gauge(I believe). I don't know the diameter of the smaller one.
Thanks Richard that would be a great help. Then I can get up close and see the real deal.
I've paid more attention to TR25W's over the years than I should have... kinda like a vulture flying over a herd of diseased cattle, looking for the one i was going to pick off of. Great affordable parts donors for unit singles projects. And have ended up with a kinda reverse Stockholm Syndrome, am strangely now attracted to the damn things. Poor red-headed stepchild should-have-been, I guess.
Point being, I've never seen a 69 that had the dinky 2001/02 (though it was standard on the 68) on it, always been the bigger bodied 5000 series. Nor have I ever seen a tach on any TR25W.
I would call the spares manual suspect on this point (especially as it was an early model/year publication). I'd enjoy hearing if anyone actually knows differently, this is just my observation...
I've never paid attention to them either. I've always had twins. I came across this little gem at oley last year and have learned quite a bit getting her back on the road. I'm also slowly getting addicted to the 250s. I find myself hoping to come across another one that needs a good home.
As I said, I am not really positive on the speedo application. Don't know what is listed for the 70, but it probably is the black-faced version, which wouldn't be correct for a 69... the 69 should be grey-faced.
Certainly on Triumphs, black-faced speedos.'n' tachos. weren't actually listed 'til '71 parts books, although they're a well-known '70 mid-year change.
The above parts book was printed with tacho. RSM 3003/01 and "SSM 500/03" (sic). These have then been crossed out and replaced with RSM 3003/13 and SSM 5001/03 respectively. RSM 3003/01 and SSM 5001/03 are both grey-face, only RSM 3003/13 is black-face.
The '70 A50/A65 parts book also lists grey-face SSM 5001/05 (and /04) speedos. and RSM 3003/06 tacho. so it seems to be the same on BSA's?
After posting the above, I went to the BSAunitsingles.com spares manuals to check, and it is just as you state, Stuart, even the mis-print.
The 70 book shows the tach as optional, whereas the 69 just shows it with no mention of that.
What I found interesting about the 70 book was the speedo cups that were illustrated... they appear to be the bellows-type, which I'd never seen until 71 OIF models, certainly not on a TR25W. The 70 tach and speedo cups both have the same part number, which does not correspond to the tach cup number for 69. The 70 numbers are F-10281... wonder if that is the same as 71 Triumph twins (it is not the same as the BSA 71 numbers)?
