The 2025 Kawasaki Ninja ZX-4R ABS is the lowest-priced inline-four motorcycle in the verified U.S. comparison here, with a $8,999 manufacturer-listed MSRP. That does not prove it is the cheapest across the entire U.S. market: available price evidence confirms five models or trims, not a ranked list of ten. The comparison below separates official prices from a secondary-source figure and excludes destination charges where they are not stated.
Verified 2025 inline-four prices
These are new 2025 model-year motorcycles with a confirmed inline-four layout in the cited material. Prices are U.S. base MSRPs, not out-the-door totals. Manufacturer charges, dealer fees, taxes, title and license may add to the amount you pay.

| Model and trim | Engine and type | 2025 U.S. price evidence | Source quality and qualification |
|---|---|---|---|
| Kawasaki Ninja ZX-4R ABS | 399cc liquid-cooled inline-four; small-displacement sportbike | $8,999 MSRP | Kawasaki U.S. model-year specification sheet. Kawasaki says its listed base MSRP excludes charges and dealer fees. |
| Kawasaki Ninja ZX-4RR ABS | 399cc inline-four; higher-spec sportbike trim | $9,699 MSRP | Kawasaki U.S. model-year specification sheet. Same engine family as the ZX-4R, but a distinct, higher-priced trim. |
| Kawasaki Ninja ZX-6R, standard non-ABS | Inline-four supersport | $11,399 MSRP | Kawasaki product material; this figure is for the standard non-ABS trim, not an unspecified ZX-6R variant. |
| Suzuki GSX-R600 | DOHC, liquid-cooled inline-four supersport | $11,999 MSRP | Reported by Cycle World’s 2025 buyer’s guide, a secondary source; not verified here against Suzuki manufacturer pricing. |
| Honda CBR600RR | 599cc liquid-cooled inline-four supersport | $12,199 base MSRP, plus $600 destination charge | American Honda’s 2025 product page states both amounts. Destination is additional to base MSRP. |

What the prices establish—and what they don’t
The ZX-4R is the lowest verified price, not a proven market-wide winner
At $8,999, the ZX-4R ABS is the lowest-priced entry among the models with prices verified above. The evidence does not establish a complete census of 2025 inline-four motorcycles or prices, so it cannot support the broader claim that this is definitively the cheapest in every U.S. listing—or worldwide.
#1 Best Overall
- FITMENT: Fits XJ1100 (1982) 1100cc inline 4. One kit rebuilds all four carburettors. Confirm your carburettor type and model year before ordering.
- WHAT'S IN THE KIT: Core parts for all 4 carbs - carburettor body gaskets, O-rings and seals, brass jets, needle valve, springs and clips. The variant adds diaphragm.
- FIXES COMMON FAULTS: Cures hard starting, rough idle, stalling and fuel leaks from worn or aged carburettor parts on the inline-4.
- BUILT TO LAST: Precision brass jets and fuel-resistant nitrile rubber seals for accurate metering and a lasting seal.
- CARBFORGE PROMISE: Dedicated to motorcycle carburettor rebuild kits, backed by responsive 1-year manufacturer support.
Trim and engine layout change the comparison
The ZX-4R ABS and ZX-4RR ABS are separate trims with a $700 MSRP difference. Also, “sportbike” styling does not make a motorcycle an inline-four: models with twin-cylinder engines do not qualify for this comparison. Check the exact engine layout and trim before comparing prices.
MSRP is not the out-the-door price
Honda explicitly lists $600 for destination in addition to the CBR600RR’s $12,199 base MSRP. Kawasaki cautions that listed base MSRPs exclude charges and dealer fees. The cited prices do not establish a final dealer quote, which can also reflect local taxes, title, license, fees and inventory conditions.

How to use this comparison when shopping
- Confirm the model year and trim. Check that the listing is for a new 2025 motorcycle and identify ABS status; the ZX-6R figure above is specifically for the standard non-ABS version.
- Ask for an itemized out-the-door quote. Have the dealer separate MSRP, destination, dealer fees, taxes, title and license so the listed base prices can be compared fairly.
- Verify the price with the manufacturer or dealer. MSRP and availability can vary by model year and change over time. The GSX-R600 figure here comes from a secondary buyer’s guide rather than Suzuki’s manufacturer material.
- Compare the riding role as well as the price. The ZX-4R is a 399cc sportbike; the 600cc-class models are supersports. A lower purchase price alone does not show which engine size, riding position or use case suits you.
Why the list has five entries, not ten
The available model-specific evidence supports prices for the ZX-4R, ZX-4RR, ZX-6R, CBR600RR and GSX-R600. Kawasaki’s lineup also identifies the Ninja 1000SX and 1100SX as inline-four models, and the 2025 1100SX displacement is 1,099cc, but the cited lineup material does not establish their 2025 prices. Including them in a price ranking—or adding other unverified motorcycles to reach ten—would imply comparisons the evidence does not support.
