Like many of the Coventry makes, Triumph had their roots in the bicycle industry, beginning motorcycle production in 1902.

The best bet is to track down one of the specialist restoration bibles for the 500cc models. Read this in conjunction with the factory manual and parts book (replicas easily availiable at Triumph spares guys) and it will give you all the answers.

Working entirely from memory.... The 500cc bikes have a 120mph speedo and the 650cc bikes have the 150mph ones. However it needs to be the right one and the string of numbers on dial are the giveaway. Sorry - not sure what exact model suits your bike but I think it is SSM5007/03

The revcounter is the usual smiths one and should match the speedo.

In 1970 the instruments changed from the 'grey faced' ones (grey circle in the middle) to the all black face. I have seen very early number bikes with grey faced instruments and thats where the restoration books are useful as they often specify 'from engine number blah blah ....'

I'm sure I have a tatty black face 120mph speedo someplace in my pile of munt. You are welcome to it but its cosmetically challenged. Replicas and nos are availiable and probably not a bad way to go.

Try going to the home page of the main site and look in manuals I think there might be a manual for the 1971 Daytona 500 listed there, also check the main site to see if there are any pictures of the bike itself

hi paul and welsh wizard,i have tried looking in the gallery but they are all taken from a distance and i would like a close up,the speedo and rev counter that was on when i got the bike are new(indian made)i think and as i say its way out on both speed and milage almost double of what ive actualy done or doing the rev counter seems as if it does not want to exceed 3,000rpm when i know im revving more,regards john.

The other thing to check is the speedo drive gearbox at the rear wheel.

Again the factory parts book will tell you which version you should have.

"Triumph Tiger100/Daytona" by J R Nelson gives year by year changes to the 500cc models. I've had a quick look and there's a photo of a 1970 with "Daytona Super Sports" on the sidepanel. And according to the same book, grey face 4:1 tach and grey face 1600 revs/mile (120mph) speedo were fitted that year.

It sounds like your clocks are not genuine Smiths, yes? If the speedo is one of the modern repro ones it may be set up for a 1.25:1 speedo gearbox whereas you may still have the original 2:1 box. in which case both mileage and speed would be displayed as 1.6 times what they actually are. Eg you're doing 30mph and it displays 48mph

The tach may be a 2:1 ratio (not sure if modern repros are 2:1 ? ) and your Daytona doesn't rev higher than 6K rpm thus your tacho reads a max of 3K rpm.

hi graham,i have had lots of answers on this and a lot of various answers some say grey some say black face, as my t100t was built in october 1970 it could have had either i think but a very kind person has supplied me with a black faced 5007/02 in good condition(thanks again paul in n/z)so i will be giving it a bit of tlc and on it goes and i will be trying to source a 3003/13 rev/c but thats another subject,i took my v5c to my local dvla office to try and regain the proper titles on it at the moment it only has triumph as make and nothing as variant it should have t100t daytona and super sport but these seem to have disapeared into dvla land i had to show evidence as to why they should put it back on so gave them mag articles a copy of the front of my replacement parts book which has the full name they have had to send it to swansea so fingers crossed, it may seem a trivial thing to them but its the integrity of the bike to me for future owners,regards john.
