Kawasaki Z H2 (MY2020) vs BMW S 1000 R (K63)
Kawasaki Z H2 vs BMW S 1000 R: no fairing, no excuses. Here's how to pick.
You'll hear the Kawasaki Z H2's supercharger whine the moment you crack the throttle, and it's already pulling hard from low revs. The BMW S 1000 R reads each turn of your wrist literally, with no spectacle laid on top. It builds speed exactly as fast as you ask.
So which one do you buy?
The Z H2 has the edge if…
Character, looks and sound
By a nose: Z H2
The Z H2 carries slightly more attitude. Most of that is more distinctive styling and a better engine note. A close call, and a personal one.
The S 1000 R has the edge if…
Racetrack use
Edges it: S 1000 R
On a circuit, the S 1000 R feels a little sharper. The difference is a sportier chassis and more feel through the bars. The margin is thin, and setup can close it.
Sporty riding on twisty roads
Nose ahead: S 1000 R
On a twisty road, the S 1000 R edges ahead. Not by enough to settle it alone.
Daily commuting & city riding
Narrow edge: S 1000 R
For the Monday-to-Friday grind, the S 1000 R pulls a nose in front. Credit friendlier manners. Your own commute could easily flip it.
Which one's the smarter buy
Depends what you want it for
The S 1000 R costs less, but that gap doesn't make it the better buy. Neither bike is the clear winner on value.
What makes each one tick
Z H2
Top gear at a lazy crawl doesn't bother the Z H2, yet the same engine turns explosive the instant you ask for it. Its heft keeps the chassis from getting nervous at high speed, and the suspension soaks up a bump before it reaches the seat. The blower chirps on every roll-off.
Nils rode the Z H2 in Austria in 2020 (NastyNils Testride).
S 1000 R
On Angeles Crest Highway, the S 1000 R's wide handlebar flicks it from one lean to the next, and you don't have to muscle it. Corner entry doesn't unsettle the front tire, even with heavy braking still loading it. Its fork and shock settle as one when it's loaded.
Nils rode the S 1000 R in Hungary in 2021, and in Austria and Spain in 2025 (NastyNils Testride).
The Voice of Experience
What actually separates them
- The S 1000 R has the lower wet weight: 439 lb (199 kg) vs 527 lb (239 kg).
- The Z H2 makes more peak power: 200 hp (147 kW) vs 165 hp (121 kW).
- The Z H2 makes more peak torque: 101 lb-ft (137 Nm) vs 84 lb-ft (114 Nm).
Which one for the way you ride
Comfortable long-distance riding
Both miss here
Long-haul comfort is a weak spot for both. If you tour, shop with that in mind.

Known problems to check before you buy
Z H2
No confirmed faults on file yet. That's not the same as fault-free.
S 1000 R
- Premature failure of individual coil-on-plug units (pencil-type) One or more ignition coils fail; symptoms: misfires, cylinder dropout, rough running, check-engine warning. Typically one coil fails first, then others follow. Recommended community solution: replace all 4 ignition coils simultaneously. Special tool (BMW 12 3 621) and airbox removal required.
- Coolant loss via the weep hole of the combined oil/water pump The combined oil/water pump can develop a leak; coolant exits via the weep hole at the rear of the oil pan. Two seals: if the first fails, coolant leaks externally; if the second fails, coolant mixes with oil (critical). Some owners report recurrence after warranty repair.
- Cascading error messages: ABS, TC, engine management, crash sensor simultaneously Simultaneous illumination of multiple warnings: "ABS Pro Failure", "TC Failure", "Adaptive Headlight Failure", "Crash Sensor Failure", "Electrical system critical". Often traceable to loose or corroded battery terminals. CAN bus communication errors cascade across all systems.
- Strong vibrations above 5,500–6,000 rpm The inline four-cylinder without a balance shaft generates noticeable vibrations at bar ends, mirrors, and footpegs. Mirrors become blurry at highway speeds. Numbness in hands on longer rides. Considered a design characteristic (weight saving from the absence of a balance shaft), not a defect. Community remedies: heavy bar-end weights (HVMP), Rizoma Stealth mirrors, foam pellets in clip-ons.
- Jerky throttle response below 3,000 rpm (ride-by-wire) Jerky, unharmonious response from the ride-by-wire system at low rpm and constant part-throttle operation. Particularly pronounced in Dynamic/Race mode. Cause: lean mapping for Euro 5 compliance. Community remedies: BoosterPlug/Red-Chip module, Rain/Road mode in city traffic, ECU remap.
- Quickshifter (Shift Assistant Pro) intermittently non-functional Quickshifter stops working on upshifts from 2nd to 3rd gear and above, while 1st to 2nd works. Causes include pinched or damaged 4-wire cable, incorrect chain tension, and software error. Community solution: quickshifter reset, inspect chain tension, and check cable for damage.
- "DDC!" error message and failure of electronic suspension control "DDC!" error message on the display, suspension settings no longer adjustable. Causes: battery terminal issues, CAN bus errors, connector issues at fork/shock. Affects only vehicles with the optional DDC suspension.
- Engine stalling when pulling the clutch, at traffic lights, or when shifting Rough idle and engine stalling, particularly on MY2021–2022. Cause: Euro 5 lean-mixture strategy in ECU mapping. BMW released a software update in January 2022 that resolved the problem for many owners.
- Failure of the combination switch (start/stop/kill switch) due to heat/UV The PCB-based combination switches (introduced from the BMW S 1000 platform in 2009) can develop hairline cracks in the circuit traces due to thermal expansion. Symptoms: motorcycle will not start, intermittent electrical failures. Occurs particularly after parking in direct sunlight. A cross-platform BMW issue since 2009.
