Performance Profile & Rider Fit
Best For
Rider Profile
| Best For | Ideal for beginners and returning riders; forgiving power delivery and light weight also make it a fun commuter or track-day starter for experienced riders. |
| Purpose | A lightweight sport bike for spirited canyon rides, commuting, and entry-level track days rather than long-distance touring. |
| Rider Fit | Compact and light at 164kg dry with a manageable 785mm seat; sporty but not extreme riding posture with mild forward lean and small windscreen. |
| Character | Nimble, approachable, and revvy parallel-twin sportbike that punches above its 399cc for grins without intimidating newer riders. |
| Not Ideal For | Not for riders wanting big-bore highway punch, two-up touring range (tiny 3.7L tank), or any off-road use. |

⚠ Safety Recalls (2)
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.

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.
