What's wrong?
In NHTSA campaign 25V531, the oil level system on 2024-2025 Triumph Daytona 660 motorcycles is the focus. The dipstick is the part owners and technicians use to confirm engine oil level. That oil feeds the crankshaft bearings, which support the spinning crankshaft and need steady lubrication whenever the engine is running.
On affected motorcycles, oil movement during aggressive deceleration, when the bike is slowing hard, lets air enter the oil system. That air causes oil pressure drops and interrupts oil flow to the crankshaft and bearing surfaces. Without enough lubrication, internal engine parts are damaged, and the engine can fail.
There is no warning sign before failure. A rider is not expected to see a light, hear a clear sound, or feel a consistent symptom before the oil-flow disruption damages the engine.

What happens at the repair
The final dealer repair is still in development, so treat it as free once Triumph opens it. At the dealer, a Triumph technician will increase the engine oil capacity and install a redesigned dipstick to address oil flow disruption that can damage the engine. Parts and labor are covered under the recall once the repair opens. Repairs paid before the recall notice are handled through Triumph's limited warranty, not through a separate reimbursement program. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
