In February 2018, Suzuki filed a statutory recall with Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) concerning the Chain, covering the GSX-R1000, GSX-R1000R. The filing affects 980 vehicles manufactured between January 18, 2017 and November 21, 2017.

|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | February 15, 2018 |

| Vehicles affected | 980 units |
Filing in context
The Chain is the most frequently cited component category in this archive, appearing in 2 of its 4,890 filings. This filing is one of 27 Suzuki notifications from 2018 in this archive. For scale, 2,817 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 10 months.
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。
