In its advertising around the World, BMW maintains that the 17 model has not lost power due to Euro 4, and the power output remains 199 hp at the crank.
However, there are several dyno vids, mostly via magazine shootouts, which suggests there has been significant power loss, perhaps by as much as 10+ rear wheel HP.
Here's what I've got so far:
1) Brentuning claimed their dyno had the 17 "soaring above" the 15 model https://brentuningmoto.com/?news=we-just-bought-a-2017-s1000rr-part-3. This appears to be an exception though.
2) Fastbikes conducted a dyno shootout, which showed a loss of 10hp from the 15 model (go to 3:50). To be fair this was not back to back. Total power was 177/8 at the rear wheel. It ate the Japs alive, but Aprilia was clearly king:
3) Visordown also conducted a dyno shootout with very different results. In this case, the 17 model made 175hp at the rear wheel, and was beaten by the Suzuki and matched by the Kawasaki. Strangely in most other shootouts the Beemer eats the japs in terms of outright power:
4) Most recently, a track day shootout conducted my Motorcycle.com. (Go to 8.00) rated rear wheel HP to be 177.1 hp:
5) And then there's this thread, which posts a link to the Seven Liter Bikes review, whereby the testers makes the 17 model out to be dying from asthma and by far the least powerful bike there (with about 192 at the crank)! Not sure if I believe this one.
So the evidence is stacking up that the 17 model has lost a mopeds worth of power than the previous year. Output seems to be around 175 to 178, and correct me if I'm wrong, but the 15/16 models were making about 185+.
I would love to see a back to back dyno, and side by side roll on tests, showing stock 17 versus 15/16 models. I've looked far and wide and so far no one has made any such videos. I've emailed BMW Australia and reached out for some more information on its HP claims...three weeks later I'm yet to receive a response.
