How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- A lightweight sport bike for spirited canyon rides, commuting, and entry-level track days rather than long-distance touring.
- Built for
- 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.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.

Safety Recalls
⚠ 1 recall 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.
These recalls cover some 2019 bikes of this model. Whether one applies to a specific bike, and whether the repair has already been done, depends on its VIN — check your VIN with NHTSA or ask a dealer.
