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

Zitat von Aussie Import im Beitrag #3 Until you measure the power at the rear wheel, instead of at the top of the piston.

I've seen 136bhp on bmw websites |

Rear wheel?probably about 120 bhp, still better than my R90s, that had about 53Bhp! And it still can shift a bit. |

Zitat von Adrian Nurney im Beitrag #6 The only bike that I know of which had the same power at the rear wheel as specified by the manufacturer was my 1985 R80. The factory claimed 50 hp and that is what it tested on the CC Dyno (San Jose, CA) at 8K rpm ! - right before both valve rocker needle bearing cages broke. Oddly, it ran just fine and I didn't even know about the destruction and the needle bearings sitting in the valve covers, until I removed the covers to perform the 4K valve lash inspection and a handful of bearings dropped into my lap on both sides of the engine. That bit of drama required a complete top-end warranty rebuild on BMW's dime, at which time I had it upgraded with R100S parts. (That was the last time I had a motorcycle tested on a dyno.) It is my understanding that shaft drive motorcycles typically loose about 15% of their power between the crankshaft and the rear wheel. Chain-drive bikes about 10%.

Zitat von Adrian Nurney im Beitrag #5 maybe the figure you're looking at is PS? 100KW = 135.96216173039 PS

YouTube, reviews or whatever no one seems to use the Bhp figure correctly..134-136 depending on day of week |
|
|
Dare I add 3.5 Bhp for my Akrapovic......? |
|
|
Probably 0.35bhp. (I have one too!) |

BHP is an imperial unit of measurement, the SI (metric) equivalent is the kilowatt kW. |
