lost 2hp ..

[buzzz90]

I wonder if that was summat to do with that weird French rule about bikes sold in France having a maximum output?

IIRC, this is due to German insurance companies. In Germany, there are steps in bike insurance cost, based on power. 98PS represents one of these steps.
I'm sure, the R1100S could have been more than 98PS by design otherwise, but 98PS should be close enough to the aimed output, and they have chosen not to cross this line at that time.

PS is referred to as "metric" horsepower. If, by metric, they mean "decimal", then it's not even that metric. Bit of a cop out really. Why wasn't 100kg chosen, instead of 75kg?

Why not go truly metric and scrap both HP and PS, CV etc and go kW?

If the smaller figures worry you, use Watts. Even Harley Davidson's would look powerful. Hee Hee.

Or centiwatts.

We went there, (in Sweden) in the 70’s and came out halfways, so to speak.
In Early ‘70’s an engine in an automotive magazine would be specd in hp, for power, and in kpm for torque.
mid 70’s, all of a sudden, power was in kW, with hp in paranthentis, and torque in Nm, with kpm in paranthesis.
The transition between kpm and Nm went well, but for hp and kW it did not.
So, now, an engine in a Swedish automotive magazine is specd in hp and Nm.

I guess it’s the same (with the hp)
as it is with your pint of beer: it will never change.

A strange mixture!

I've come across kp back in school/college, but not used to express torque (obviously along with a distance measurement). Not that I can recall, anyway.
I think maybe the hydraulics industry use it, to express linear force. Of course the name Volvo figures strongly in that industry, or used to. I've lost touch.

They may take our HP .... they'll never take our pint

Bloody sauce I say.

Ahem - excusez moi monsieur, my glass appears to be 68ml short. Furthermore, your ale is a trifle cold, pallid and fizzy, which simply won't do.

So, it would seem that a relatively feeble German horse equates to a French 'steam horse'. How curious?

Yeah and decimalisation lost us 40d in its conversion, so they want the pounds value less and to stiff us on a beer measure too .... it can only be politics .... and I've still not got the 98hp I was promised

It catagorically states here

http://www.barrierobsonmotorcycles.co.u ... XERCUP.pdf

that it's 98hp which they reckon is 72kw (but which compares to the figure quoted by Buzz90 of 96hp)

Yet back in the museum in the fatherland the R11S is listed as 98ps ..... so somewhere someone's telling fibs ...

So can we all return our R11S's to BMW asking for the full 98hp versions that it says on their brochure, mind you on my V5 it reckons my engines an 1150 too I think

[slparry]

Just to widen the discussion, I checked the R12S brochure at
http://www.barrierobsonmotorcycles.co.u ... chures.asp
and it says 122hp / 90kw ... and the 90kw converts to 120hp .... so it's not just the R11S that's been over sold

[Corvus]

They're German.

So there's a very good reason for all this.

Rounding errors.

Neither are strictly right by my reckoning. But both are near enough.

Steve,

Maybe it comes from the fact it's BHP and not HP.

Finally, maybe BHP = PS

I always thought it was the other way around to what the article reckons! They refer to it as "break", which doesn't lend any credibility.

Brake horsepower is surely measured on a brake! And therefore accounts for the various losses mentioned.

I don't think this is the root of what was discussed on the last few posts though.

By the way, I'm not suggesting we don't bring it to the party. Far from it. Bring it on, I say!

Cheers.
