Just announced last week by SRM - Smiths Instruments have released a electronic version of the classic speedo and tacho. The speedo has a pick up sensor inside a pseudo drive hub and cable up to the clock replicating the original fitment. The tacho takes its input off the coils. A Commando green blob version is out soon. Price is pretty reasonable for the whole speedo kit about 179 Pounds Stirling or $295.

It's about time,,,,,,,,, Now maybe I can get rid of my bicycle speedo.

Resurrecting this topic.

Did anybody get one of these speedos?

I don't think SRM are doing these, at least I can't find them on their site.

Just wondering did they work out OK?


Thanks in advance

Looks like a nice upgrade, but a pity I could no longer reply to the policeman's question of 'do you know how fast you were going, sonny?' with a finger wagging like a windscreen wiper to imitate the St.Vitus' dance action of the speedo needle and 'somewhere between 5 and 65 mph, Officer' :oops:

I would think the green blobs would be a top seller - just need to keep hanging in there...

I wonder if Joe S is watching?
 
Many thanks for the replies.

I'm even more specific, I need an NVT faced speedo!!

I've had a good google around the interweb but can't find any reviews.
 
Hi,

I got both SRM speedo and tacho some time ago. The speedo never worked properly, I was able to calibrate it with the ignition on without running the engine, but once I started the engine it didn't work. Got in contact with SRM who passed my enquiry to the smiths technical man who did never really answer. Swaped to speedhut instruments (http://www.speedhut.com/) and they work really well. Got a difference of 250rpm in tacho readings between smiths and speedhut, speedhut being more accurate. SRM does no longer sell these instruments, so I guess there is a reason for this.

Are you using resistor plugs or resistor plug wires?

He is. In fact it was us, Andover Norton, who first approached the new Smiths people about making the original instruments again. Whilst at first they sounded like it could be done, a bit along the way they came up with electronic alternatives which were of limited interest, us wanting a 1:1 replacement for the original Commando instruments. Also, while still in discussions, various other parties jumped in on the project, with the Smiths people indicating they'd eventually be selling the instruments to all and sundry, including the green globe ones.
Had the proposed new instruments filled our basic criterion, i.e. 1:1 replacement of the originals, we'd have fought that, but as is we were no longer interested in the project. To me, even the Taiwanese neutral dial replica Triumph-type speedos and tachos are nearer the mark than these "replica" green globes driven electronically.

Joe, thanks for your reply, and very interesting, too! Good to know we've got a direct line to so many key people here 8)

I've been reduced to buying the Taiwanese grey-face clocks for a Domi project, and up close they're clearly built to a price - I've yet to see how they perform.

I've seen Smiths clock faces advertised, and wondered if they could be transposed, but the replicas seem to be an entirely different construction.
I wonder if these faces would fit the electronic versions?

It would also be a great opportunity to bin off the leaky tacho drive.
 
Bogus,
Leaky tacho drive no more- see Andover Norton part# 06-7254 or, if you want to modify your housing yourself, 06-7255.

I put a Taiwan tacho on my B25 as an experiment to replace the small Smiths I was using, very well damped as the needle does not wander, the Smiths is staying in storage until the other project I bought the Taiwan for is finished.
 
When one acquires a bike in England it's always equipped with a MPH gauge. Instead of buying a «refurbished» speedo from suspicious sources, I've taken a different approach. Copied a face of the MPH speedo and redesigned it for KPH, a little math was used, let them print and placed it on the original dial sheet and let the instrument be calibrated by a speedo/tacho specialist.
I think this can be done also with a Taiwanese instrument.

I've definitely got an education from this thread about the Smiths digital speedo's!!

Fritz, that's a very clever solution, what software did you use to design the clock face (PS or Illustrator an a another?) what did you print the face on? What material did you use, I'm presuming it was not paper!!

Thanks in advance

I'm Using GIMP (Gnu Image Manipulation Program) but of course you can use use Photoshop or Illustrator for it. You should keep in mind that all the white windows where the screws going through and the ones for counters should be black because they are cut out out by the speedo man after it's placed on the dial sheet.
I'd made a PDF and sent it to someone who makes signboards where it's printed on a self adhesive foil.
