Throttles are cheap. I prefer replacing them, and always have some in stock. I was just curious of how it could have a dead zone in the middle of the course. I might open it to see, but I won’t bother fixing it.

I told you how. That link shows how ( BTW, great work dissassy one of them, larsb - Thank you for the disassembly). 2.5v. Wears out at the most used place in the throw. I bet we could find similar problems on the Ducati Multistrada forums. Lol. My best guess. Loses its resolution. Its ability to give good signal repeatably. Cause tht is right in the middle. The 2.5v.
Lol my best theory. Guess. Whaddever you call it. Good throttles are not cheap. I could show you 100$+ Hall or Pot style.... W/O problems that require multiple replacement. Last the life of the bike... years...

I agree with that logic possibility, and to Fechter’s as well.
Any throttle, like any saddle, no matter how expansive they are, can break at first crash, simply because grips and saddle are sure to hit in all crashes. I have tried about all the throttles available over a decade and found very few that I like. My favorite ever was only 15$ but seem to have disappeared 5 years ago. QO is the name, if someone sees them somewhere.
Opposite to most, I like that a throttle has a dead zone at the beginning of the course, and also that its course is short and linear. I believe every rider has his own preferences. I have friends who like thumb throttles and I hate them.

Cable-operated works, too (and the cable adjustment allows for adjusting deadzone at the start point).
Can use thumb or grip type, anything that pulls a single cable would work. The only potential problem is some cables don't pull *enough* cable, so you either use something like the Cycle Analyst v3 to translate teh voltage range you do get to what the controller needs, or use a pulley to change the cable pull ratio itself.
One example:

You can also operate them with brake levers, to use for proportional regen.

I like the universal left or right thumb throttle myself, I have never tried anything else. I'd want a throttle on left and right side, with the cruise function where if left at the same throttle position for X amount of time it goes into cruise. I had that on the Conhismotor KT kit, and I liked it. I never had it hooked up to the brake lever so it took a bit of getting used to flicking the throttle to end the cruise. I never had no regen or abs braking hooked up, yet. I like a quick response throttle from 1/4 to 4/4 throttle, but less response from 0 to 1/4, but maybe that delay is just in the motor winding, I always go for 4T or 5T windings, but maybe its different speed response feeling if I go 8T motor and more power over all, instead of 36V 40A go 72V 80A, or get the 5T in a very small rim for that extra torque.

Could never go back to a hall throttle, if I break my domino or the pot wears out I'll replace it with another one, they're honestly that good

Yeah but they aren't $10 or $15.
Still nice to have a good throttle.

Yep, but I didn’t like the idea of cutting a 100$ throttle to make it half grip. So I sold it to a friend. Full grip are not for me, but I’d like it if I had a clutch.

Domino makes Hall throttles. They really that bad, hall throttles? I have one here, ( Grin, thumb, cheapo, at least one) but I couldnt imagine a cheap throttle period. The ( even cheaper ) 0-5k throttles that come with the kits stink. Its your connection to the machine. A Ducati Domino Hall throttle is > Domino 0-5K throttle.... I am going out on a limb to say, but only rhetoric and hearsay since I dont have experience with both. I only say this.. cause the Ducati engineers used one over the other ( even tho they could have any throttle they want in production of the best MC on earth), and based on accuracy or signal and whatnot...and longevity.. I could see how it could be advantageous...
I thought Hall throttles were used for longevity over a 0-5K throttle. Why do they exist? Anyone know another reason?
Yeah crash anything and it might become trash. Lol. Yes, I doubt a duke was designed to sit upside down on its bars for maintenance.
M. Rhino dont even use a CA ( monitor diy assy and signals much? lol) so he cannot see the TH. V. at glance.... I love the datalogging of the average throttle value / ride.. tells alot about the ride and consumption.
It is all V/sec/sec on the +5v reference line.... Quite a small amount of V. change, over time, you are considering. Tuning a V/S/Sec input can be trickyu. TPSdot. Looking at it, do you even know if the throw ( of your particular pot) is a 1:1 ratio even before it is converted into a digital signal?
Come to think of it, many ( 3 or 4 over) redundant TPS systems into OEM electronics of modern cars are 0-5k pots ( or other resistances, there are many many common values for those pot(entiometer)s. )... but they dont see rain.
I have tuned a few. TPSdot(s).

Price point, the ability to spit them out on the production line for cheap, availability, people keep buying them, construction costs (cheap to build)

Every bike should be built to be serviceable upside down in the trail IMO.
And, I am a rider. All the time I spend fixing things is riding time lost. Every bike should be built to suffer minimal damage in a crash, IMO.
Then, I ride fast. Sometimes way too fast and I am conscious of this. My survival does rely on constant awareness so, no dashboard, no distraction. 8)

So true. They prefer to rely on cagers awareness than their own. So many are potential blind victims, with 2 ton vehicles passing them 30 mph faster, driven by distracted people in a hurry. City streets are not much safer than trails. In the event of a crash, help is coming sooner of course, but danger is all around.
I prefer to be in the position to hit a car, than risking being hit by one. And most of all, I prefer the mountain trails, where obstacles are not moving and none of them hating you. Danger yes, but peaceful danger. :wink:
It seems most USian people see biking as a sport, something you do for fun.
In much of the rest of the world it's more utility transportation, they did not make the idiotic mistake of designing most communities around assuming people should / need to own private automobiles.

Some are seeing the act of riding as a philosophy, everywhere in the world. In human history, the bikes are the new horses and the cars, the new carriages. Riding and driving are fundamentally different, wether people are seeing them as leisure, sport or transportation.
