You got one of the last of the last, huh?--a special edition Bullet described here: https://www.royalenfield.com/uk/en/motorcycles/classic-models/classic-500-tribute-black/

Well chosen, and welcome to the Forum!

Thanks for the welcome,  many questions to come,  anyone feel the need for a rev counter as thinking about fitting a digital one for the running in period, tia John

You don't really need  a tachometer, unless, that is, you just want one, in which case you absolutely must have it! The topic does come up from time to time, so a quick search of the Forum's archive of past postings on the matter should scare up a whole host of good recommendations.

In a pinch, you could just use a grease pencil, tape strips or similar to mark off the revs on the speedo glass or its bezel for various gears using the table found at https://forum.classicmotorworks.com/index.php?topic=8325.msg95843#msg95843 and a calculator, namely:

Miles per hour at 1000 rpm for each gear:

1st       5.29
2nd      8.04
3rd     10.64
4th      13.36
5th      16.19

Hence 65 mph (65 ÷ 16.19) is about 4.014 x 1,000 rpm, or roughly 4,000 rpm in 5th, near 5,000 rpm in 4th, and so forth.

Of course, our Enfield speedos are not exactly renowned for scrupulous accuracy, but this might still help you from overtaxing your ride during its break in period.

Thanks Haggis

Pick your happy reves,

Thanks for the graph. Do you know how many teeth on the front sprocket for that graph? I think some come from the factory with 18 teeth, others (like my Trials 500 version) with 17.

Do you know what the green vertical lines indicate?

For me, not having a dedicated tachometer is one of the best aspects of owning an RE. It keeps the experience pure and uncomplicated. 
I once owned a 1930 Model A Ford for a decade or so and never once needed any RPM data for shifting purposes. If you asked an old-timer when the right time to shift was, he'd likely just shake his head in disgust or say something to the effect of, shift when you're supposed to. And of course they would be correct.  It's all part of learning about your machine. I liken it to dancing.  You tell your partner what you want to do and they'll let you know what they can or cannot do. Shift up when speed is needed needed.  Shift down when power is needed, and be mindful to never lug the engine.  You'll soon find the sweet spot for every shift. Another example of man and machine.

So with all that happy nostalgia out of the way, you can use your speedometer as a tachometer in a sense. Shoot for the middle of the range for each gear and you can make adjustments from there in time. Short shifting is enjoyable, but once the engine is broken in and loosens up you'll find there's a lot of grunt available in 2nd and 3rd gears. That's the silly grin range.  You'll find it.

1st gear: 10-20 mph
2nd gear: 20-30 mph
3rd gear: 30-40 mph
4th gear: 40-50 mph
5th gear: 50 on up

Thats for an 18 tooth front sprocket,  2.11 ratio. 18/38.
Your 17 will be 2.24 ratio, 17/38.
Difference of around 300 rpm at normal cruising speed.
