Many people have had issues with premature wear of the camshaft lobe and the valve followers due to the factory installed cam chain tensioner. The cam chain tensioner is almost a problem with any KTM Duke 790/890 or KTM Adventure 790/890. All of these bikes have issues with these specific problem within the first 10,000 miles. This cam chain tensioner failure can led to catastrophic engine failure leading to the engine being unrepairable and needing a completely new engine.
Brake light will not illuminate unless full brake pressure is applied. Incident 1 - This happened 2 separate times. Once 9/2023 at 2765 miles and again 5/2026 at 20,505 miles.

My KTM dealership diagnosed and replaced the brake light switch both times. My understanding this switch is a "pressure switch" Incident 2 - 9/2025 at 18,199 miles my cruise control would not disengage when ap…
