    Engine "modes" are simply throttle blade opening differences vs throttle twist grip position.

    Full power is 100% twist grip = 100% open throttle body blades
    50% poer is 100% twist grip = 50% open throttle body blades
    so on and so forth.

    I thought the stock exhaust had a valve that helped with torque in the lower revs range, which remains closed and then opens when the revs really start to build.

    Bearing in mind this bike makes 214 hp, and even if a chunk of that is made in the high rev range - I suspect that will still leave plenty of power to be getting on with before you get to that bit.

    I guess I was thinking that the engine modes were like different engine maps - that must be feasible even if not implemented..? Although come to think of it I’m working from experience with my TDi Golf which has a turbo which would made a Fireblade insane! I know it was possible to change engine maps relatively quickly (15 years ago)..

    The exhaust servo simply manages existing engine attributes, doesn't add anything.

    But again, all you can manage are existing engine capabilities - not add non-existent ones.

    So at best you will have the engine maximum capability reflected in the Full power setup and then power removed from subsequent "maps".

    There is no magic, never has been. The engine has a capability of X. This is a mix of efficiency, sound and fuel consumption requirements as delivered.
    Any maps with different fuel and ignition characteristics will still only be manipulating the existing capability of the engine.

    My current test bed SP2 is essentially in SuperStock trim and went from 158rwhp in US form, 175rwhp in Euro form and is at 188rwhp in tuned Euro form.

    But these power characteristics still only represent what the current package is capable of - the next step up is different cams.

    Does the new Fireblade have variable Velocity Stacks ?

    My R1 does, simply from one position to another at certain revs I think. I believe the Ducati Panigale has this feature that helps with differing the power delivery at different revs.

    I think it works - longer Velocity Stacks for low down power/ torque and then shorten the Stacks for high end power - something like that.

    Nice engine picture.....(of an R1 :rolleyes::D)

    I guess I was think the maps might do "magic" in the same way that on detective tv shows, they can miraculously perform image enhancement of CCTV to zoom in on number plates or people's faces.. Maybe a small turbo that spins up quickly at low revs is the only way this could be achieved then :rolleyes: (or maybe not).

    Yikes, I wish I'd never asked now - it's all getting way too technical :(

    Really interesting though.

    The idea behind the variable length of the air intakes (Velocity Stacks) is to change the air pressure feeding into the cylinders - clever mechanical engineering and the principles of physics - very clever.

    Not sure if the 2020 Firebalde has this technology ?

    Lovely looking Ducati V4 motor....

    Panigale V4 motor.png

    And here is a close up of the velocity stacks and you can see the rails in the middle on which they slide up and down - according to engine revs.

    If they were to be fixed in a certain position then it would be a compromise - because at low revs one shape is ideal, - with low volumes of air - and at high revs another - because of air flow management.

    So to get the best performance it is better to have velocity stacks that can vary in length - I think it was Yamaha that sussed this out :rolleyes:

    I still do not know if the new Fireblade has this feature or not ?

    Same can be said about S1000RR, isnt it the first year when they finally enjoy the shiftcam engine ? As I understand it wasn't available last year.

    Apparently the US model will be limited to 186bhp only

    Ah well, no excuses for BMW if they fail to performing then.

    Yeah totally agree and they were suck first round too.

    Tire management was extremely important at Philip Island.

    I love hows its maxed at 299, but the revs still climb, even slots in another gear :D:D

    I was trying to figure out where the clip was filmed - doesn’t look like anywhere on my daily commute into central London but at 299kph who knows :cool:

    Spoke with my Honda dealer yesterday, and they are expecting their demo SP in 2-3 weeks..
