A nooby called NPFiorito asked me this question, but you guys are the experts.

It's the letters that are important. Whilst XD doe's indeed mean December 1970 you need to be careful due to Triumph's build year system.
Triumph's build year ran from July/August to June/July depending upon who you ask. (This was the same as the UK reg. system.)
So in fact the bike was built in December 1969 for the 1970 season. The other give away is the grey faced clocks, a "real" 1970 model would normally be fitted with black faced clocks.

I hope this helps

The meters may not be original... I remember my Dad building this bike in the 80s, I don't know where all the components came from or what was original or not. Are there any other characteristics that I can use to help me identify what kind of bike I have? So Webby this is a 69 not a 70? I have had a hard time finding many pictures of a 70 T100 and some have 2 gauges and some only 1. I would really like to bring this close to stock as I can so any info is good info! Thanks for your response

Hi NPFiorito,

For the purpose of ordering parts etc. your bike is a 1970 model.
It's just that Triumph would have considered any bike build from July/August 1969 thru to June/July 1970 as a 1970 model. This causes confusion between the build year and the calendar year.

The give aways are the meters (the grey face I think were changed in late 69/early 70) and the front brake plate (yours is a later one with the 90° cable pull, the earlier ones were a straight pull) As for other differences, I'm not sure I'm no expert on T100s.

Good Luck with the bike

All the best

My '70 Tiger has grey faced clocks.......it was an early one. My original '70 "C" model had a black faced one. The change was made during the model year.

That's the first time I've heard of July being the year change-over month in the two-letter aging scheme...

August is all I had ever heard before today, and I've been around a while...

As a guide the 1st August is probably good, this would tie in with the UK registration dates of the period.

All the 7 inch brakes, as fitted to the 500s, were of the cranked lever type. Only the 8 inch brakes had differing cable pulls.
The bike is indeed a 1970 model, built in December 1969.

As far as I know, tachometers were optional on most 500s but standard on the T100R Daytona. You would be lucky to find a definitive answer as to whether the clocks should be grey or black faced. As yours has the grey ones, I would go with that.

There should be a model code stamped as part of the frame and engine numbers. This should be T100C or T100R. It looks like your bike is a T100R Daytona (which had twin carburettors), The T100C had a single carb, folding footrests, high-level exhausts and a smaller (6 inch) headlight. I think 1970 Daytonas were painted Jacaranda Purple.

Further proof that I know very little about T100s
Thanks for the additional info Andy!

All the best

It is indeed a T100R! Thanks Andy Manuals are on the way.. The frame and engine numbers match but the old registration I had doesn't match the bike, which is why I thought I had a Tiger.. The actual vin starts with DD. From what I've been able to find that it was built in April 1970. I had a neighbour who's into old Nortons come over and he says everything looks fairly "unmolested" as far as he can see and that mostly everything is there and in decent shape.
