2023 Ktm 790 Adventure R problems

Filed Nov 6, 2026 · Suspension · CA

While riding on a public road at moderate speed, I began experiencing unusual handling characteristics. The motorcycle felt very much like it had a soft or flat rear tire, with the bike swaying from side to side. I stopped to check the rear tire pressure, believing that might be the cause of the unusual handling. Instead, I discovered something far more alarming. The swingarm pivot axle had migrated approximately 1 inch out of one side of the motorcycle’s frame. Upon examining the opposite side, I could see completely through the frame opening to the swingarm. The swingarm itself had shifted so significantly that it was no longer aligned with the opening in the frame through which the pivot axle is designed to pass. In other words, the structural connection between the frame and swingarm had substantially separated while I was riding the motorcycle. The swingarm is an integral part of the motorcycle’s frame and rear suspension system. Its pivot connection is essential to maintaining the proper relationship between the frame and rear wheel assembly. I consider this an extremely serious safety failure. Fortunately, I was traveling on a straight road at moderate speed when the problem became apparent. Had this occurred while cornering, riding aggressively, or operating off-road, the consequences could have been catastrophic. A loss of rear suspension integrity and alignment under those circumstances could easily have resulted in a serious accident or fatal injury. I am particularly concerned that this may represent a broader product safety issue rather than an isolated mechanical failure.

Under moderate ambient air temperatures of 75-80F the gas tank gets pressurized and if opened when more than a gallon remains this pressure causes fuel to spray out of the gas tank.

The motorcycle is just over 1 year old. Has less than 1300 miles on it. The bike does not start, the manufacture is not helping the dealership work on the problem. The motorcycle has been with the dealership for more than 3 months at this point. As an adventure motorcycle, a no start problem or if the bike shuts down while riding this could be a dangerous potentially deadly situation. There is also a known issue with the cam shafts failing at low mileage also. There is an active forum and Facebook pages with thousands of members world wide that are experiencing major defects on this model with no response from the manufacture. It is one of the most expensive motorcycles in this style and it is also one of the most unreliable. Please reach out if you have any further questions or need more details to push forward. I would like the manufacture to be held accountable for their shortcomings and potentially life threatening decisions made at the expense of their customers.

The bolt that holds the swingarm to the motorcycle fell off. The shaft vibrated out partially and half of the swingarm came loose which cause the rear wheel to be misaligned so the bike went down the road 'sideways'. On the forums and facebook groups, this is a common issue among owners of this model of motorcycle and it's predecessor (KTM790). Apparently, the manufacturer does NOT torque the bolts properly and apply loctite. In 40+ years of riding dozens of motorcycle, I've never had this critically important bolt fall off. This is regularly happening to owners of this model of KTM motorcycle
