Subject: Safety Recall: 2025 CB1000SP – Excessive Engine Oil Consumption Causing Engine Failure (L26, L27, L28) (Update 1)
February 2nd, 2026 – Update 1: Notification letters for this Safety Recall were sent out on Friday, January 30th, 2026, to all owners of affected units.
BACKGROUND:
Due to a design issue, affected units may consume excessive engine oil. Under conditions of high engine negative pressure, such as during engine braking, oil can be drawn into the combustion chamber. In severe cases, this increased oil consumption may cause connecting rod failure, engine seizure, and sudden rear-wheel lock?up, increasing the risk of a crash.
This safety recall is launched in two Phases:
Phase 1 - Current
All affected units will be inspected for engine oil level and oil contamination. If oil is found contaminated, the engine will be replaced. If the unit passes inspection, engine oil will be refilled, and customers will be advised to check the oil level after each refueling until Phase 2 repair is completed.
A one?page customer instruction sheet is provided in the Service Bulletin MSB-II-6-25. Please print a copy and review the steps with the customer. Customers can also bring their motorcycles to the dealership for oil level inspection and refill in every 500km interval after the Phase 1 inspection. This follow up inspection is covered by campaign code L28.
Phase 2 – Expected to become available in mid-2026
The final repair method and the required countermeasure parts are still under investigation. This service bulletin will be updated once the information becomes available. Customers will also be notified by mail at that time.
AFFECTED UNITS:
2025 CB1000SP: 80 units (dealer inventory = 44 units)
STOP SALE:
All affected units in dealers’ inventories must have this Safety Recall service completed prior to sale. Should a dealership sell an affected unit that subsequently causes an injury or damage because of this Safety Recall issue, the dealership will be solely responsible to the damaged party and will be required to defend and indemnify Honda Canada for any resulting claims.
