Defect

The engine control unit software is incorrect. During a 1st-to-2nd gear shift, if the transmission goes to neutral instead of engaging 2nd gear and the throttle is opened, the engine over-revs. If the rider then engages 2nd gear without disengaging the clutch, excessive force is applied to the drivetrain. This causes the drive chain to stretch abnormally and, in the worst case, the chain may detach or break, rendering the vehicle inoperable.

Corrective action

On all vehicles, replace the engine control unit with a corrected part that incorporates an over-rev prevention control. Additionally, inspect the drive chain for abnormal stretch; if abnormal stretch is found, replace the drive chain, engine sprocket, and rear sprocket with new parts. Because preparation of the remedy parts requires additional time, owners will be notified of the defect as a precaution and will receive a subsequent notification to return their vehicle once parts are available.

状況

 エンジン制御コンピュータのプログラムが不適切なため、1速から2速への変速時にギアが2速に入らずニュートラルになった時に、スロットルを開けるとエンジンが空ぶかし状態となり、その状態でクラッチを切らずに2速に入れ直すと、動力伝達装置に過大な力がかかる。そのため、ドライブチェーンが異常に伸び、最悪の場合、外れるもしくは切れて走行不能となるおそれがある。

改善措置

 全車両、エンジン制御コンピュータを、過回転防止制御を追加した対策品と交換する。また、ドライブチェーンの異常伸びの有無を点検し、異常伸びが認められた場合は、ドライブチェーン、エンジンスプロケット、リヤスプロケットを新品に交換する。 なお、改善措置用部品の準備に時間を要することから、使用者に不具合の内容を通知して注意喚起を行い、準備が整い次第、再度入庫の通知をする。
