There has been some suggestion that a lot of the test bikes supplied by BMW may have not been exactly standard, there is also some suggestion that some magazine reports may have been altered when it appeared the BMW wasn't the best.
Someone has done some research on this and sent me the following. You make your own mind up.
------
This is some of the information I have found. If you go to the BMW Australia web site this has the Power and Torque figures for the BMW S1000RR. You will notice the BMW max torque amount is 112N-m / 9,750 rpm, this is relative important. Their max power is 142kW / 13,000 rpm.
The ZX10r figures are the same max torque value at slightly higher RPM, so 112N-m / 10,500 rpm and zx10r Max Power is rated above the BMW at 147.1kW / 13,000 rpm.
From the Fast Bike Magazine I got their Dyno Chart and Top Speed Chart before it was changed.?
Please notice that the Torque curves and Maximum Torque are of the BMW and Kawasaki are almost identical as indicated in the specs from both Manufactures.
While the zx10r power is not significant above the BMW, it is above the BMW, however in the Top Speed run it shows how affective the zx10r Ram Intake is hitting it’s top speed in 23.15 seconds whereas the BMW struggles above 170 mph and hits about 178 mph at 30 seconds.
In a file BMW Motoradd Australia sent to their Dealers, there are two bikes, one is a customers bike and another unit, they are trying to indicate that the stock bike has 186hp and the when both the ECU and Exhaust Pipe is fitted it is 195hp.
What I believe they’re showing is a bike with the BMW Power Boost Kit ECU 186hp and the other with the BMW Power Boost Exhaust Pipe and BMW Power Boost ECU 195hp.
If you read the current Cycle Torque article the information has been supplied by BMW so it talks about the BMW improving the low and mid range torque and getting 14 hp increase in power, however in BMW own Dyno charts there is no 14 hp increase.
There is a 14 hp jump from the 172hp to 186hp and then the Kit Pipe gives it 9 hp more to get to 195hp. Other wise you pay $6,000.00 for 9hp. You actually get 23 hp for the $6,000.00 so it is relative good value. However when you see the top speed shoot out the BMW needs a lot more power the keep up with the zx10r.
It also has with both parts fitted a hole, in the torque curve at 8,500 to 9,500 rpm and this makes the bike very hard to ride, and getting on the power out of corners this is because Maximum Torque is at 10,500 rpm. All the local riders who raced the BMW is FX or Superstock commented about this difficult power delivery. Glen Scott, Jeremy Crowe and Craig Coxhell.
In the Motociclismo Magazine web site it dyno figures from their dyno test at Monza, Kawasaki was just in front of the BMW but it has better Ram Air so it would have been better on a fast track like Monza, at this stage I don’t have the actual results of this test rumored to have Aprilia then BMW and then Kawasaki. Possibly this is Europe pride affecting the results as the Aprilia Factory has 161 hp.
I'm guessing most Journalist have never ridden a stock BMW or Honda or Yamaha etc.
On another note the Power of the Yamaha at 160hp and this is consistent with dynos here in Australia, the Yamaha weights 216kg so how will a stock one win in FX or Pro Stock.?

There was more info that was sent to me but some of it is top secret..
specially when bmw went around making the claims they did... they could hardly been seen to fail at their one aim with the bmw, to have the most powerful litre bike...
