# Service bulletins for the 2026 KTM 990 Duke

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

1 bulletin from NHTSA, as of 2026-10-19.

- [KTB2602](/bulletins/11031351.md), 2026-04-15, Service bulletin: WHEELS. To fully exploit the potential of a Supersport motorcycle, appropriate performance tires are required. In our opinion, the Michelin Power Cup 2 best meets this requirement. The disadvantage of these tires is, that there is a low\-temperature threshold at which rubber loses elasticity and becomes brittle, called the glass transition point. Rubber breakdown in the cold can manifest as a tiny crack or many larger cracks around the tire. To avoid damage, the Michelin Power Cup 2 must not be handled below 41°F \( 5°C \) in transport and storage.
