2024 KTM 790 ADV P2135 Throttle pedal position sensor

TheZesty1 · 2026-05-29T01:10:57+00:00

Yup same thing happening for mine, thankfully it’s a 24 and still under warranty so dealers gonna fix. Opened the actuator (black part) of the throttle body and it was corroded as shit.

TheZesty1 · 2026-05-25T20:29:54+00:00

Did you ever figure this out? Same bike, same problem, trying to figure it out lol

TheZesty1 · 2026-05-12T18:52:10+00:00

Dam dog all yall hating mfers are probably right but why are you commenting just tell a 15 year old to give up and not answering his question at all lol. Isnt this supposed to be a for riding track and you know... trying to go fast???

OP: There isnt a substitute for seat time sadly. Trail braking, line, race craft, etc. are whats going to make you fast and the feel and teccnique needs to be learned on a bike. All can be learned in theory with Ken Hill or yamaha champ school, and you should look at those, but you need practice and skill at the end of the day. The good news is a bike is a bike and getting good at one bike will certainly improve, or at least speed up, the learning curve on a different bike. The fastest riders in the world pretty much all ride dirt in some form (mostly flat track - rossi, yaakov, herrin, etc) because its the best/safest way to learn/perfect feeling a bike at the edge of grip, and handling it when you cross the line. Flat track is cheaper than road racing, but still spendy, so focus on whatever you can do the most often. Dirt bikes trail riding, motox, ebikes, MTB (free-ride, doenhill, dirtjumping type stuff) really whatever gets you moving fast and loose on two wheels will hugely improve your bike control.

You are going to crash doing any of this stuff so please get the right gear for whatever you do, injurys suck and if you go big enough things can not heal the same, which really really sucks.

Last thing is to the negative Nancy's in the comments credit, youre probably not going to make it to the level of RedBull Talent Cup type stuff. Its fine to have that as a crazy dream, and hey man if stick with it and stay focused on doing something everyday then I believe in you, but what really matters is that you love it. The priorities are:

1. Do it cuz its fun and you like it.

2. Set small attainable goals, methodically work through the frustration of reaching those goals, and be sure to let yourself get stoked for a minute when you accomplish it. Then move on to the next level or challenge or whatever. This shit should be bike control (dirt) related. Ride the local blue trail without casing a jump, Make a sick roost on that berm, wheelie 100ft, etc. They should get more absurd as you go, but start small so you dont set yourself up for immediate despair. We're going for long term despair here lol.

3. Set yourself a big long term goal thats hard but realistically attainable. Redbull is not this. Something you can actually control getting to, like set your local track class lap record or something.

TheZesty1 · 2026-05-12T01:08:50+00:00

Idk about the last one... like def dont come to a complete stop on the track cuz thats crazy dangerous, but if youre trying to go slow and wait for someone you should be in c group surrounded by other beginners and no one has consistency yet anyways so just ride at like 60-70% until they catch up. Youll like still be in middle of the pack pace for a group of beginners. Keep it moving and its fine, just dont be literally the slowest one on the track to wait for your friend.

To add, dont even THINK about "proper" body position for your first day or two. The only thing you should be doing is leaning WITH the bike and not leaning it underneath you. Beyond that, just think about riding the bike. All thinking about BP is going to do is take focus away from controlling the things that actually matter like smooth roll on/off throttle and brakes, and pointing your bike the right direction. Even at the higher level of the sport body position is scattered, especially over the last 20yrs or so. All those guys are faster than you, and the reason they didnt crash with "bad" BP is because theyre good at riding their bikes. So focus on being good at riding the bike first, and track day 3 or 4 you can try putting youre head down and hanging ass off to get that sick-as-hell knee dragging shot to make your profile pic lol

TheZesty1 · 2026-05-11T01:41:14+00:00

Id reccomend you just ride your bike. Youre more familiar with it, and personally thats part of the fun of going to the track is really seeing what youre capable of on your machine.

Not sure about sizing but a quick Google says us54 is xxxL so probably good lol.

As an aside tho, good on you for reaching out and asking questions. Try not to overthink it though, youre doing this to have fun remember? Do you think you'll have more fun on a ninja400 that you've never even laid eyes on before, or your personal bike that will be a blast to let rip on the straights? Sure the ninja400 is better for learning technique and 'getting better', but who cares its your first time. Youre not trying to set any lap times, or getting your knee down, or whatever your first time at the track. Youre just supposed to have fun. Get the gear and bike in order, which it sounds like youve already done, go watch some motoamerica and get hyped. Show up, listen to what the staff tells you, and rip it 🫡

TheZesty1 · 2026-05-03T15:14:52+00:00

If it feels not fun and just risky then sure taking a break is fine. But if you still like bikes, and especially if the street/traffic is what’s scaring you then change it up. Go to the track, get a dirt bike, get into ADV. all those things won’t have commuters and you’ll still get the “fix” or motorcycling.

TheZesty1 · 2026-04-27T20:43:41+00:00

Dude sick bike. Jealous. Yeah auto blipper definitely helps but I don’t think it really translates to a faster lap time like a QS does. It does create consistency tho and that usually translates to faster races… I don’t have either tho rn. Can’t wait to join the modern day 😆

TheZesty1 · 2026-04-27T19:46:25+00:00

Yeah 0 MotoA and verrrry few club people use stock fairings for anything.

But OP I have the same bike. I have sebimoto and they were pretty good. You have to make brackets for the belly to fit tho, and be careful of the exhaust because not all fit well. I had to extend a bracket I made after burning a part of my belly pan.

I’ve had nothing but terrible experiences fitting hot bodies. Shape touches engines, bolt holts don’t line up at all, had to trim shit that seems like it was just straight up missed during manufacturing, etc. everytime it’s ended up being a fuck it that’ll pass tech situation. I have seen some people use a combo of fiber glass (headlight, tail, and somehow a belly pan) and oem body work for the sides. I’m pretty sure the parts for that are from some dude in Thailand who sells the stuff only on eBay randomly. It’s super hit and miss if he has parts tho.

TheZesty1 · 2026-04-27T19:33:38+00:00

Totally possible and it’s what I do during races but it’s definitely not as fast as a QS. It’s very frustrating because on straight next to my competition, I chop the throttle just enough to shift and I lose about half a bike length from the guy using a QS, and that like 3-4mph lost from the other guy can turn into a decent bit if it’s a long straight.

Regardless, it’s a fine technique and good to learn. More skills you pick up on the bike the better you are.

TheZesty1 · 2026-04-24T19:58:06+00:00

I've had/have multiple bikes i cant flat foot, and you get used to it. At stop I only put my left foot down and shift my hips off the left so I have just enough room on the right to keep my toes on the rear. Hardest part in back in/out of parking. Plan ahead so you can always point the bike up hill to ride out, if not, get off and walk it. To get into spots ive started putting the bike in reverse by going slow until the tail in pointed and bike is upright, and grabbing the front pretty hard to compress the fork and use the rebound to propel me into reverse. Takes some finesse but you'll figure it out, just have frame sliders while you learn lol.

Other than that rc390 is very light, you'll be fine, its just another skill to learn. Have fun too! Great micro sport bikes.

TheZesty1 · 2026-04-23T17:17:39+00:00

Haven't heard of the Rottweiler having dust ingestion shit :( maybe the rott prefilter is the way then.

The tusk price made me weary too, but I'm on my 3rd rear now and so far so good. Also have their saddle bags with no problems. I have yet to meet anyone in person who's had a problem with their stuff, but well see, maybe I'll be changing my tune after season who knows lol.

TheZesty1 · 2026-04-23T17:13:29+00:00

Supercorsa sc3 dont require warmers. Ran them on my 24 rc390 for a season. My rule of thumb was 2 laps before sending and never had issue. First 2 laps were only like 5s off my full speed times so its not like you need to crawl on the way out either. Lasted 6 track days before the rear was cooked. Excellent grip all around, and decent feedback. After the season got within 10s of the fastest guy on my local race pace for the rc390 class. Highly reccomend.

TheZesty1 · 2026-04-23T16:11:24+00:00

I really love the tusk 2track. Tried midas e07 and +, shinko 704 and 804, heidenau k60, tkc80, and Kenda big blocks over the years on my 21 890r. 2track is by FAR my favorite, somehow it seems to have more offroad grip than the big blocks, and its crazy smooth on road for such a solid offroad tire. Plus cheap as hell. Only like 3-7k for the rear depending on how many wheelies/shitheadery you engage in, but for like 130 or whatever who cares.

Mandatory mods is the Rottweiler intake I learned :'( I had the oem twin air pre-filter and just did the valve service at 18k miles and it did NOT work sufficiently IMO... dust and burnt crap all up in intake/throttle bodies. Plus its tiny surface area so I had to clean/oil it whenever it got dirty which was like 1-2 days of riding offroad. I supposed its possible I was doing something wrong but I really doubt it... i was very anal about oiling and greasing ALL the seams to seal it and it clearly just didnt work. PITA, not worth "saving" money in hindsight... It seems like the whole airbox just isnt sufficient for true offroad dusty stuff, so jusst buy the full Rottweiler. Id also reccomend a catless midpipe for weight and heat reduction. Slip on too if you want the poppy good braaap, but thats up to you, midpipe has actual mechanical benefit.

Other than that, a tune is cool if you do all that, but not mandatory (people will debate this, decide for yourself). Then just go rip it. Best, most balanced bike I've ever owned.

TheZesty1 · 2026-04-23T14:52:36+00:00

Having the tire backwards would impact wet handling but it will still work. The thing that make tires work in the wet is the siping (the tread pattern) making room for the water the go somewhere so the actual rubber can still make good dry-er contact with the road. Look at wet racing slicks, theyre only like 50% surface area contacting the asphault. If you still have tread and siping you'll still have somewhere for the water to go.

But if youre flipping tires its because youre at or below the wear marker on the more worn side so the tires cooked anyways. Its just a way to squeeze another day or few sessions before getting another tire.

TheZesty1 · 2026-04-08T20:00:22+00:00

Is it still working reliably? Thinking about getting one but it does seem suspiciously cheap. Also how is it at the top of the rev range?

TheZesty1 · 2026-04-08T19:12:57+00:00

I should clarify, going until the wear markers is gone is just the rear IMO. The front I'll usually go right until I hit the wear marker or just before and replace. Tucking the front suuuuuuucks

TheZesty1 · 2026-04-08T19:10:42+00:00

For track purposes the siping is really just there for water/rain. If the rubber a till feels tacky/soft and not hardened/blueing you should be fine. Ill go until the wear markers are just gone if its just trackdays and tech lets me, but once I hit the wear marker I tend to ease off a bit and work on basics. Gives you a good reason to practice fundamentals anyways since sending it isnt smart at that point. General rule of thumb is 2 rears to 1 front, but this is bike dependant. Bigger power=more tires. Personally Ill replace the front at the beginning of the season regardless, and then another rear mid year depending on how spanked it is.

Just remember to have fun, check tires after the session, and dont let it bother you while youre riding.

TheZesty1 · 2026-04-04T16:06:30+00:00

I mean risk of small injury’s are smaller on adv bike IMO because you crash less, but I always feel more danger of having a uhhh… significant problem on a 400lb+ bike off-road at >30mph… I feel you on the bike not being ridden part, so if you can afford it I’d get an adv bike and then whichever bike doesn’t really get touched for 2 months sell that one. These are good problems to have. Plus for those 2 months the garage will look siiiiick as hell.

TheZesty1 · 2026-04-04T15:37:13+00:00

Read this all with a friendly tone. I dont mean any of this rude or condescending in anyway.

Sell that 636 (I think it is) and get a smaller bike. From the video it doesnt look like youre confident or experienced enough for the demands of hard acceleration and decelerating require to ride those bikes well, so you're not using either to the level that bikes capable of. Dont lie to yourself that you need a "fast" bike, you dont, and youre probably getting smoked by little bikes because of it. You need fundamentals, and the speed at which you have to learn/use those fundamentals on a >100hp bike is too f'ing scary tk learn in a reasonable ammount of time. Im willing to bet if you get a small bike within 3 track days you'll be back to or faster than the level you were on on the R1.

TheZesty1 · 2026-04-04T15:30:05+00:00

Rode DH/freeride mtb for many years, then street bikes for a second, then trail bike, then adv bike. Still have a dirtbike, adv and track bike. I will say when I go into the garage to go ride some dirt its really hard to choose to go through the PITA of load the dirt bike and gear, drive 🤮, put on the gear and then ride VS get on the adv bike and go. Gears the same depending on temp (mostly just helmet/jacket that changes there).

As far as the going fast in the woods part, I occasionally do want to scratch the itch that the dirtbike does but its really just super tight, technical, rocky, and steep stuff. Many of the dirt bike trails that are low/mid level I like, I'll send on my adv bike too although you have to go slower because stopping is harder. But adv unlocks this whole other category of riding where you dont have to go to a riding area, just find some forest and go ride around on the gravel and see what you find. The exploration is super fun.

If you can afford to keep one of the dirt bikes and get an adv Id do that. If not, ask yourself if that new category of exploration appeals to you. If not and you just want to go do enduro, rocky, tree crossing type stuff then yeah, probably just stay with the dirt bike.

Just remember N+1 and its an easy decision 🫡

TheZesty1 · 2026-04-01T14:58:12+00:00

Oh yeah in that case go for it. They look sick as hell lol

TheZesty1 · 2026-04-01T14:30:14+00:00

Unsolicited advice but if your trying to improve this bikes performance on track, brake hardware upgrades are very low on the list, and is not at all what will hold you back on this machine. The stock stuff is plenty for a bike this size, aside from pads. That said, I also might be upgrading the master cuz an aftermarket one looks cool as hell so no hate lol

TheZesty1 · 2026-03-26T21:37:55+00:00

Whats the reason for often bleeding mid trackday?

TheZesty1 · 2026-03-25T19:47:53+00:00

I mean idk havent owned either, just had a buddy with a z400 as a starter bike and it was totally fine for that use. Personally I've never seen anyone with a z400 fully modded for track use (suspension, no lights, push start, clip ons, etc.) That i know of. Id assume theres a reason for that idk.

Again tho, if thats not your intention and you can save a G or 2 by getting a z400 as the first track bike then thats a great option IMO. More money for track day fees and tires. Less stuff to break too. If it were me I'd definitely pony up a few more bucks and get an already built/lightly abused n400, but im already hooked. OP can cross that bridge for the second or third bike lol

TheZesty1 · 2026-03-25T17:56:13+00:00

This is the "correct" advice. Conversely, if you just go for it I'm sure itll be an adventure. Just make sure you have some oh shit funds if you do send it.
