No direct effect on the qs but an effect on gear change as there’s less of a torque delta and in theory should make programming the qs less difficult.

Revs also drop less bc gears are closer so don't have to retard timing as long. Regearing a 21 bike would be quite the endeavor

That’s why there’s a decrease in torque delta but it’s actually a shorter ignition cut not retard. Yes there will be less manipulation of the ignition once the new gear is selected.

As for regearing, it shouldn’t be difficult at all. I’m guessing there’s no other changes so a complete cassette swap would do it. I’d get the new one dlc coated or something. Expensive probably, but not difficult.

Torque delta? The QS is a microswitch. Its knows on and off.

Are you 12? I said it has no effect on the qs.

Toque delta is the difference in torque. In this case it’s the torque being transferred from the pinion to the cog. So there’s not as big of a difference in this torque transfer between the cogs in subject.

But, I’ll correct myself about programming the qs… it’s programming shift strategy and is all done via the ecu (which is actually what I meant).

Not to get into the weeds on QS operations but I think the ECU uses a combination of ignition cut and timing to accomplish shifts. Unless, you’ve seen a Ducati white paper on their QS protocol.

It does both, you’re right. Principle is the same for no lift shift, Ducati or otherwise.

I LOVE this!

Ask me a reasonable question about a statement I made, and I'm coming straight back outta nowhere with an insult!

And then I'll address your question :'D

I literally said that the change in gearing has no effect on the QS… so how tf is his question reasonable?

I don't know what else the author would mean by "electric shifter." I can see how having a closer ratio would make shifting smoother, but the QS doesn't care. It just send a signal to the ECU when its activated.

New gearbox matches World Superbike ratios with a taller 1st, 2nd, and 6th gear. Reduced gaps between the first three gears encourage smoother up and down-shifting, makes life easier for the electric shifter, and improves accelerating and when entering a corner. The taller 6th gear permits a higher overall top speed relative to final drive gearing.

Wider ratios = possible longer ignition cuts and have to retard timing more to make shifts smoother. Closer ratios will unsettle the bike less

I thought they may have been talking about a gearbox redesign (not just the ratios).

From my understanding, there's no changes in the gearbox design. Just diffferent gears in the box. They probably improved the QS but we'll have to see it in person to see if that design has changed. Per reviews, no one had any issues with the QS but that could be down to the improved cooling. I've heard the 21 can be a little difficult at times.

Is the Ohllins shock on a V4S the same as the TTX or can be converted?
