- Over 1,000 units affected in the UK alone, approximately 1,253 machines worldwide
- The cause is said to be faulty surface finishing of the cylinder bore
- A permanent fix is still under development; dealers are initially carrying out an inspection
The Honda CBR600RR is unwillingly back in the headlines. Just around two years after its long-awaited return to the European market, Honda is forced to initiate a safety recall for the 600cc supersport. Affected are machines from model years 2024 to 2026, where excessive oil consumption may occur.
Rough Cylinder Bore Identified as Cause
Honda UK has officially confirmed the recall. A spokesperson stated: “The 24-26YM CBR600RR is now subject to a safety recall related to oil consumption. In the UK, the number of affected units is just over 1000.”
Honda has already been able to narrow down the cause in the CBR600RR. In some cases, the surface finish of the cylinder bore is said to have been too rough. This is attributed to the tooling used during the machining process. The rough surface can cause excessive engine oil consumption.
In the US, where the recall has been underway since December 2025, the National Highway Traffic Safety Administration (NHTSA) describes the problem in even more drastic terms. According to the agency, the dropping oil level can cause oil pressure to fall to the point where the connecting rod bearings seize. In the worst case, this could lead to the rear wheel locking up, or engine oil reaching the hot exhaust system and creating a fire hazard. According to manufacturer documents, approximately 1,253 motorcycles are affected worldwide.
Inspection Rather Than Repair as an Interim Solution
Affected owners are currently being contacted. However, the recall measure does not yet consist of a permanent repair, but rather a precautionary inspection at the dealership, which is expected to take approximately one hour. Honda’s spokesperson stated: “The dealer will carry out an initial inspection of the bike and advise the customer accordingly. This is a precautionary measure at this stage to ensure the safe, continued use of the motorcycle.”
Honda is still working on a permanent solution. In the meantime, dealers are offering affected customers a complimentary oil top-up if needed. In the US, Honda expects to be able to offer the final repair from around July 2026. The repair will be carried out free of charge for all owners.
Dealers May Continue to Sell
Notably, Honda has not halted sales of the CBR600RR despite the ongoing recall. Dealers are still permitted to deliver the affected models to customers. However, buyers must be informed about the situation before purchase and confirm this with their signature.
Similar Issue Already Seen on the CB 1000 Hornet
The CBR600RR recall comes just weeks after confirmation that all Honda CB 1000 Hornet models are also being recalled due to excessive oil consumption. In the case of the Hornet, Honda suspects a different root cause — namely the piston rings and piston specifications, which may allow oil to enter the combustion chamber. As with the CBR600RR, the Hornet recall is also a precautionary measure while the exact cause continues to be investigated.
A Honda UK spokesperson stated at the end of January: “Following a thorough investigation in collaboration with Honda Motor Co. Ltd (Japan), we are now instigating a safety recall. Customers will be contacted by direct mail with all relevant information.”
The CBR600RR: Technical Overview
The CBR600RR returned to the European market in 2024 after a seven-year absence. The supersport is powered by a 599cc inline four-cylinder engine with 16 valves and a double overhead camshaft. On the dyno, the engine produces 108.4 hp (79.7 kW) at 14,000 rpm and delivers a maximum torque of 59.5 Nm (43.9 lb.ft) at 11,200 rpm.
