Honda Cb750 Recalls

The Honda CB750 has 7 recalls spanning 1975 to 2025, with the most serious affecting 2025 models where an improperly manufactured crankcase bolt can leak oil onto the rear tire, reducing traction and raising the risk of a crash for the rider and others on the road.

The 2025 model year recall stands apart as the only one relevant to current owners. All other recalls date to the late 1970s and cover specific trim variants from that era.

On 1979 CB750K and CB750KZ models, two separate engine oil concerns exist. The oil filter boss, which anchors the oil filter retaining bolt, can crack under engine heat and pressure and release the filter entirely, dropping oil onto the road. Separately, repeatedly revving the engine hard immediately after cold starts can split the countershaft oil seal, allowing oil to reach the rear tire and reduce grip while riding.

The 1977 CB750A has an electrical issue where the main fuse holder contact spring can lose tension, raise electrical resistance, and eventually blow the fuse, cutting all electrical functions including ignition and lights at once.

Going back to 1975, the CB750F shares a wet-weather brake concern with the GL1000 and GL1000LTD: applying the rear disc brake in heavy rain can cause a noticeable drop in braking effectiveness before it gradually recovers, and if the rider does not compensate with more pedal pressure, stopping distances extend considerably.
