The valve train of my bike failed and left me stranded in the woods. There were no signs or warnings beforehand. After further research online, I found that this issue has been happening quite a bit. Luckily it happened to me while my bike was parked. The issue is the valve train is wearing out prematurely and causing the bikes to run poorly or not run at all. My bike has 13,000 miles on it and other bikes have had more or less miles when this issue occurred. I've worked on several motorcycles with three times the miles and never had an issue with the valve trains being chewed up like this current issue. This issue could possibly cause the bike to stop running while it is being driven at whatever speed. A bike suddenly stalling out in traffic isn't the safest scenario for a motorcycle rider. Especially if they're riding at interstate speeds. If you search online, you'll see others with this issue and it's much worse than mine. There are numerous YouTube videos and even a dedicated Facebook page about this issue. I do not have Facebook but I have attached a link with this description.

1) The vehicle TFT display containing important data such as speed etc.. blacks out on occasion. The vehicle itself is still functional but with the display blacked out the operator has no speed information, or information about the vehicle such as fuel levels and ABS control. KTM has been made aware of the issue as it has affected multiple users worldwide. 2) The indicator/blinker control switch does not engage the blinkers when pushing the switch to the left. In right hand drive markets this a particular hazard. Again, the issue is common across the 790/890 Adventure and Duke models.

I recently discovered that the brake light does not activate when applying the front brake lever. I became aware of the issue only after noticing that the motorcycle’s cruise control system would no longer engage. Upon researching the cruise control malfunction, I found numerous reports from owners indicating that failed front or rear brake pressure switches were the root cause. In almost all cases, the faulty brake pressure switch prevented the brake light from functioning properly. Online searches reveal widespread owner reports across multiple model years describing identical failures related to defective brake pressure switches. These failures impact both brake light operation and cruise control functionality. The safety implications are extremely serious. Motorcyclists may unknowingly operate their motorcycles without functioning brake lights, significantly increasing the risk of rear-end collisions. Owners may be completely unaware their brake lights are not functioning. In my case, I only discovered the defect because the cruise control stopped working. Had that not occurred, I may have continued riding without realizing my brake light system had failed. I also found reports indicating that other owners filed complaints with NHTSA and were subsequently contacted regarding dealership repairs facilitated through KTM. This suggests the issue may already be known within the manufacturer and regulatory system. Given the repeated reports across multiple KTM models and years, I respectfully request that NHTSA investigate this defect and issue a safety recall . Brake light failure caused by defective brake pressure switches presents a substantial and potentially life-threatening safety hazard to motorcycle operators and surrounding traffic. Good faith repairs by KTM should be mandated for all owners.

Tire size 90/90-21 front tire inflated with Motorcycle manufacturers recommended psi without warning it instantly deflats. I had this happen twice with the same tire. Once deflated it causes the tire to debead off the rim while riding and renders the motorcycle nearly uncontrollable. Especially dangerous in a curve or turn. My riding skill kept me upright. Yes my safety was at risk. Many riders would have crashed. and likely have but have no explanation as to why. I started a thread on two Facebook groups and one Forum that are related to my motorcycle Make and model. Many owners wrote of their experiences. with the same manufacturer of the tire. The tire is marked Tubeless but I would recommend running it with a tube. Something is wrong with either the tire or the KTM OEM wheel. It's going to kill someone. No Joke!
