Filing in context
The Engine assembly is the most frequently cited component category in this archive, appearing in 23 of its 4,890 filings. This filing is one of 18 Honda notifications from 2024 in this archive. For scale, 752 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 1 year and 9 months.
Defect
In the engine assembly, improper process controls during manufacturing of the crankcase and transmission case result in insufficient sealing at the mating surfaces, allowing transmission oil to leak. The oil loss causes inadequate lubrication and abnormal noise. Continued operation can damage the bearings inside the case and, in the worst case, cause the rear wheel to lock during riding, resulting in a fall.
Corrective action
On all vehicles, measure the transmission oil level. If the level is below the specified value, replace the transmission case with a non-defective unit and replace the bearings and related parts with new components. If the level meets the specified value, clean the case mating surfaces, apply gasket sealant, and reassemble. Note: Because parts procurement requires additional time, owners will be notified of the defect now and contacted again once parts are available.

状況
原動機において、クランクケースとミッションケースの製造工程での管理方法が不適切なため、当該ケースの合わせ面の密着性が不足し、ミッションオイルが漏れることがある。そのため、オイルの潤滑不良で異音が発生し、そのまま使用を続けるとケース内のベアリングが破損して、最悪の場合、走行中に後輪がロックし、転倒するおそれがある。
改善措置
全車両、ミッションオイル量を測定し、基準未満の場合はミッションケースを良品に交換するとともに、ベアリング等を新品に交換する。基準以上の場合はケースの合わせ面を清掃し、ガスケットを塗布して再組付けを行う。 なお、部品の準備に時間を要することから、不具合内容を周知し、準備でき次第、改めて連絡する。
