I have, I hope, worked out the gear ratios and set out below, in this posting, the road speed, as detected by GPS and as reported by the TFT , for the rpm x gear for the R1250 RS, using 750 rpm "breaks".

These were calculated by reference to 4,000 rpm in 5th equalling 100 kph on the GPS.

Oh no! Nice analysis but you�ve just reopened the �Speedo doesn�t match GPS� can of worms again!
Get ready for the �my 1956 dingbat 125 Speedo was accurate to 100th of an inch, why can�t BMW do the same in 2020. And the alternative �my VW Golf is only 1 mph out at 75 mph.....� etc.
Oh well, it will give the usual suspects something to moan about during the festive period!

...you mean like Arabic for Arabic numerals or Latin for Roman numerals...?

Do you think this is another of those Iowa-specific IT issues? They show up fine for me. (Although it has a PDF icon, it pops up as an MS Word document on my computer.)

Merry Christmas to all!

I don't know why some people can see the charts, and not others. The uploading protocol seems inconsistent and I am not literate in German.

The calculations were just a whim and took about 30 minutes to sort out. It was just a follow up on the comparison with the R100RS.

The big questions for me right now are:

How much power is enough, too little, and is there a too much?

And

Are our bikes getting too heavy, or is the weight justified by strength, durability, features and performance?

My light 12 hp, 1967 Honda CD 125 seemed fast to me, at first. Now I wouldn't even consider it as a nostalgic "project".

So where are we, that is riders, going? What is the future?

I would like to apologize to anyone I have NOT offended. Please be patient. I will get to you shortly.

I suspect the visibility thing is down to the web browser in use and the plugins installed. Chrome in Win 10 works fine as well as in Android on my phone.

For the questions you pose, perhaps start a new thread in the non RS section "Off Topic" as they are generic

I can see the chart, but it is completely blank. I think it might have something to do with Mozilla Firefox. I have noticed that some PDF downloads show up blank at times using that browser. However, I can see them when using the Chrome browser.
