Better start tooling the parts we require

Pro Stock has rules. Lots...
It’s against the rules to build chassis any longer than 70” for that class
ib has no rules to follow. No class either lol

I have been using this site for a few years: Gearing Commander - Motorcycle Speed and Drive Train Calculator v7
My experience is that a 44t rear would be a bit too much for highway or high speed use. 15/ 42 is the V4R size.

I haven’t played with a R but gotta believe it revs quicker than base or S with same gearing and same rear tire
Doesn’t it have more compression and lighter reciprocating pieces?
That’s what I based my 15/43 starting point on for base or S

^ Lower displacement at 998cc is the only internal difference that I know of.

You don’t take 5mm stroke away from a motor and it magically makes more hp
That’s not how it works
To make up for the loss of displacement the R got Ti rods, a lightened crank, and Ti intake valves. I am sure of that
They may have removed weight from the flywheel too? Dunno...

I thought it made more power (mainly) by reving higher.

I believe Injectors are rated by pounds per hour or cc’s per minute but all this is besides the point. I suggested 15/43 as a starting point for a S cuz the R engine that is quicker reving to start with has 15/42 stock
Yeah R revs higher. It hits the limiter at 16k in 1st-5th gear. Ducati admits setting this limit higher than they wanted to for when sanctioning bodies impose and take rpm
Where does S hit limiter?
*seemed like the one I rode reved to the moon

I’m not sure - 14k maybe? I see reference sources saying peak power is 15,250 and 13k respectively.

Ducati is modest. Claudio isn’t one to brag
