They have dropped Ducati's rev ceiling by 250rpm...That will make fuck all difference mind...

I'm not getting this rev limit thing. I've lost track of the rules so are we running any sort of Dorna ECU? If not, can't any sort of rev loss be adjusted by just mapping the torque differently. Rally cars have fuck all revs and 'power' but whack loads of low down torque to get past power limits.
Won't Ducati just adjust the gearing and mapping ? The thing is still a v4 after all.

No spec ECU in WSB, but DORNA/Scott Smart will have a way of checking that the adjustments are being carried out.
Power is a product of torque and revs, so no matter how much you play around with the mapping, gearing or whatever, if the bike has been capped at say 16,000 rpm by the ECU, the engine will not be allowed to turn any faster; the bike will still get to it's rpm ceiling just as quickly as before.
Unless the V4 makes all of it's power in the last 250rpm, then as paulg says, it won't make a blind bit of difference. Also, Kawasaki & Yamaha are not being given any more revs to play with... so the status quo will remain unchanged.

The next battleground will the aero. Expect to see Ducati expected to take theirs off because the others can't be arsed to make winged bikes.

If engine development is frozen under the regs how can the manufacturers make use of the extra revs? Generally they have to change cam profile to suit. If they have slotted cams the most they can do is change timing.

Revised rev limits;
Aprilia - 14700
BMW - 14950
BMW 2019 - 14900
Ducati V2 - 12400
Ducati V4 - 16100
Honda - 15050
Kawasaki 2018 - 14100
Kawasaki 2019 - 14600
MV Agusta - 14950
Suzuki - 14900
Yamaha - 14700
Why is the V4R limit set the highest?...is it becuase it's a new bike?..

In the MotoGP race last year AB's fastest race lap was 1'34.674, when it was 23c air temp and 40c track temp.

Nah. I reckon Bautista will find that easy enough. Not much difference between him and Chaz at the moment. |

Its taking AB a bit longer to get a setup so far. New bike and they havent tested there and all that. Same for the GRT Yamaha team, no data to go off as I dont think Crescent would be sharing. Cortese getting there quicker than Melandri. The BMWs doing well so far with their underpowered engines.

There are only 2 heavy accelerating corners at Assen, the rest of the circuit is fairly flowing, so the BMWs are able to exploit their handling... IMHO  |
