2021 Ktm 790 Adventure R

The motorcycle's instrument cluster (TFT Display) often becomes obscured by internal condensation (fogging), sometimes remaining obscured for extended periods of time (i.e., 30 minutes). When this occurs, it is impossible to see critical operation/safety information such vehicle speed, traction, and ABS settings. It is also impossible to operate the menu to control these same settings. The resulting conditions make vehicle operation unsafe--especially when fogging occurs while operating the vehicle. Based on extensive forum searches, this issue is a design flaw that is well-known, but largely unaddressed by the manufacturer (KTM). Many owners of the same vehicle model experience this safety issue. My local dealership has "warrantied" (replaced) one display for this condensation issue, but refuses to further remedy the issue, even though the replacement display has the same problem.

When engin is cold for more then 8 hours. Engin will start only on 1 cylinder (right), for +/- 1 minute (1000 +/- rpm), after, you will heard internal explosion, and left cylinder will start (1600 +/- rpm) . and dropping at 1400 for normal idle. With an strong gazoline smells after start-up, after 2 3 minutes smeel is gone Please note that I live in Canada Quebec

If the bike has been sitting overnight, then the first start of the day is difficult. It does not want to start and takes a few tries. When it does start it is on only 1 cylinder...this goes back to normal once it warms up after a minute or so. This began @700 miles. This problem goes away immediately if you use 89 octane fuel. I have just stayed with 89 but other owners have reported after going back to the fuel KTM recommends 91 octane or higher, the problem comes back.

When I start the bike, it sounds like the engine is only running on one cylinder and misfiring. It runs 'rough' like this for about 30 -60 seconds and the revs are sitting between 1000-1300 instead of the normal 1300-1500rpm range. You can smell fuel while this is happening. It then 'pops' and the engine runs fine after that. I live in the Netherlands, but wanted to register the issue here as well for investigation.

I just wanted to make you aware of my 2021 KTM 890 R VIN # [XXX] 2000 MILES Since new it has had a hard start when cold or sitting overnight. It takes 2 or 3 times to start and keeps stalling I stalls runs rough and even runs on one cylinder for 30 to 60 seconds. Its a 2 cylinder motorcycle. Once running it runs great rest of day. MANY folks are seeing the same condition and KTM is not responding with anything of a solution I have owned many many motorcycles and even 6 KTMS but their lack of attention here is not good. Dealers say it's normal or no problem found. My local dealer said yeah, we have seen it no real fix. The earlier 2019/2020 790 models had hard start issues but this new 2021 890 model is worse, more widespread and more severe— running on one cylinder at start up. I am a master mechanic in the auto industry and understand something is wrong. If ANYONE bought a new car and it took several times to start each morning and it ran rough for a little you would not accept it. Not only is it not great for customer satisfaction but could be hurting the engine and might be an excess EPA emission issue too.

When running the motorcycle on the manufacturer-recommended 91+ (premium) octane fuel, the engine can take up to 5 or 6 tries (over the course of a few minutes) to start when it's sat overnight. When the engine eventually does start it runs very rough on only one (of two) cylinder. During this rough starting there is an overpowering smell of raw/un-ignighted fuel coming from the exhaust pipe. There seems to be some kind of issue with the fueling or ignition timing that prevents the engine from running properly on 91+ octane fuel. Switching to a slightly lower 89 (mid-grade) octane fuel mostly, but not completely, seems to fix the issue. However this fuel is not rocommended by the manufacturer due to the high compression ratio and I'm worried that it might cause damage in the long term. The bike was taken to the KTM dealer who performed a reset of the factory ECU; however, this did not help the issue at all. Reading online, I've found dozens of people with other 2021 KTM 890 Adventure motorcycles experiencing the same issues e.g. no start, hard starting, running on one cylinder, etc. Running on only one cylinder and sometimes dying is a major safety issue.
