Safety Recalls
⚠ 2 recalls may applyPOWER TRAIN:MANUAL TRANSMISSIONNov 2020 · 20V676000
Kawasaki Motors Corp., U.S.A. (KMC) is recalling certain 2018-2020 Ninja H2 SX, Ninja H2 SXSE, and 2019-2020 Ninja H2 SXSE+ motorcycles. In the event of a gear misengagement the engine electronic control unit (ECU) programming doesn't have the capability to suppress high RPM during transmission. If the transmission gears are not properly engaged while shifting into 4th or 5th gear, high engine RPM can cause the output gears of 4th or 5th to fracture when the gears re-engage.
Risk: Damaged gears and the inability to shift can cause the engine to lock up, increasing the risk of a crash.
Remedy: KMC will notify owners, and dealers will reprogram the FI-ECU software, free of charge. Owners are advised to not ride their motorcycle until the repair has been completed. The recall began November 16, 2020. Owners may contact KMC customer service at 1-866-802-9381. KMC's number for this recall is MC20-10.
STRUCTURE:MOTORCYCLE:KICKSTAND/CENTER STANDAug 2018 · 18V580000
Kawasaki Motors Corp., U.S.A. (Kawasaki) is recalling certain 2018 Kawasaki Ninja H2 SX SE (ZXT02BJ) motorcycles. The pin for the center stand spring may have been improperly welded, and, as a result, the pin may shift or fall off resulting in the spring detaching and the center stand dropping to the ground unexpectedly and dragging while riding.
Risk: The dragging center stand can cause a loss of control, increasing the risk of a crash.
Remedy: Kawasaki will notify owners, and dealers will replace the left center stand bracket, free of charge. Owners may contact Kawasaki customer service at 1-866-802-9381. Kawasaki's number for this recall is MC18-05.
