A factory motor is most definitely built from the ground up , to produce the type of power , that specific rider needs / wants. Which most of the time , is more power , on top of the way they want the power to be delivered. A stock / off the shelf motor isn't what a lot of these fast guy's are going to like. So yes , a stock / off the shelf motor is indeed a " de-tuning " in a sense. May not be the power curve they want , but it's also a lot less power.
I don't know how to fight through the semantics here: If I choose not to bolt a supercharger on to my car, it isn't "detuned" at all. It just still is exactly what it was designed to be.
Barica would (for example) like the engine singing in the top end of the rev range as he exits a corner, the others prefer the more torquey low/mid pull to launch them out

I disagree with that assertion and that the motor designs for factory teams are built to that end. Stock is the starting point. Sure they know where a few ponies are hidden and have some directions in mind... but the development and testing will be in the future. You are acting like that HP is already delivered, tested, and approved as a package by the team and rider prior to development.
Ask yourself this........if you don't think those factory motors are that fast , why are they building them from the ground up for their riders? There isn't even a comparison. Like literally zero. Same could be said about suspension......stock stuff / A-kit stuff.........to no comparison factory stuff!
That is my whole point and exactly why calling a stock motor a "detuned" factory motor is absolute crazy-talk. We are talking about millions of dollars and countless man hours in development versus literally zero.
My opinion is that when you do something at the professional or highest level for a very long time (as your only job) that you generally have a much better feel for that sport, equipment, your body, or whatever it may be than hobbyists or enthusiasts. On top of that, some pros may actually have a better feel for certain things than other pros, but it is still greater than almost anyone else who doesn't (hasn't) put in that time. So anecdotal comparisons and general theories and philosophies don't always necessarily ring true when it comes to what a pro wants, needs, or feels.
Bottom line is , and why I got into this conversation was because someone mentioned something about stock motors vs factory motors , detuning and so forth. I don't claim to know what all the top riders want / need........I was just trying to give an explanation of why Justin may feel the need to detune his motors.
Pit Row
"I got in many conflicts with the engine engineers at first. They wanted more compression and bigger carburetors for maximum power output, but this produced uncontrollable power. In theory it looked like the way to go. In reality on the racetrack it resulted in slower lap times.
Just before the Finnish Grand Prix, I suggested we do a blind test. I said," Build me three bikes and don't tell me what is on each bike. I will ride all three bikes during practice and I will tell you which bike has the smaller carburetor and low compression". They agreed. After riding all three bikes in practice I told them which one it was and I was right. My lap times were several seconds a lap quicker on that bike too."
As for Barcia, its the same story wherever he goes.
There are some of us that "fly in the face" of that.
I'm 56.
I've been on a stock KTM 450 SXF with a different map, good fuel (VP T4) and an FMF pipe. I'm running ODI "MC" bars, Emig's Jeffro grips, a Guts "keep your butt on the bike" light seat, some graphics and a few little bolts and brackets that fell off the truck on the way to the races....(carbon master-cylinder gaurds, carbon motor mounts and the associated fasteners).
But, my suspension? Stock with my own air pressure and adjustments. Aka, out of the box...stock. And the stuff works. It's amazing what you can do with a screw driver.
The motor, also, is Box Stock. The clutch has been replaced -once- at 20 hours/just before Mammoth.
The bike now has 37.5 hrs.
The stock stuff -IS- pretty damn good.
IMO 450's need to stop being made anyways.. they are too fast and allow goons to hit 120ft jumps and crash their brains out because they have balls and no skill..
Also, if you watch a lot of training footage from moto spy or MX nation or any of those things.. the 250's hang with the 450's on the starts.. Maybe not at the nationals because the starts are longer but in SX they are just as capable..
