Owner report 11437938 · 2021-10-24 (October 24, 2021)
Starting immediately after the mandatory 600 mile service check by an authorized KTM dealer, this vehicle started experiencing prolonged cold start failures. It went from starting 100% of the time after three or less start attempts to requiring approximately ten failed start attempts before starting and running. Until 10/20/21, this motorcycle has always been fueled with either 93 octane gasoline with 10% alcohol or 90 octane fuel with no alcohol (only 2-3 times) as recommended by the manufacturer. On 10/20/21, I filled the nearly empty fuel ta…

Owner report 11437948 · 2021-10-24 (October 24, 2021)
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 …

Owner report 11438301 · 2021-10-26 (October 26, 2021)
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…

Owner report 11445504 · 2021-12-29 (December 29, 2021)
The motorycle has a hard time to start. At times throttle needs to be added to keep the engine from dying out. A modern and fuel injected bike should not need to have the throttle be opened for the bike to start up.

Owner report 11445537 · 2021-12-30 (December 30, 2021)
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.

Owner report 11445550 · 2021-12-30 (December 30, 2021)
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.
