For a four-cylinder motorcycle shortlist, the evidence here supports three Honda options and two larger naked-bike alternatives—but it does not verify ten current models or their availability across markets. The clearest starting points are Honda’s CB650R, CB1000 Hornet and CB1000 Hornet SP. Treat the figures below as market- and year-specific, then confirm local specifications before buying.
Which four-cylinder motorcycles are supported by current specifications?
Honda’s 2025 Street brochure provides comparable engine and output figures for three models. The brochure is regional, so its specifications should not be assumed to apply in every country.
| Model and source context | Engine and output | Weight and other published details |
|---|---|---|
| Honda CB650R, 2025 regional brochure | 649cc liquid-cooled DOHC inline-four; 70 kW maximum output and 63 Nm maximum torque in the unrestricted version. The brochure also shows an A2 35 kW version. | 205 kg kerb weight with manual transmission or 207 kg with E-Clutch. |
| Honda CB1000 Hornet, 2025 regional brochure | 1,000cc liquid-cooled DOHC four-cylinder; 111.6 kW maximum output and 104 Nm maximum torque. | 211 kg kerb weight. |
| Honda CB1000 Hornet SP, 2025 regional brochure | 1,000cc liquid-cooled inline-four; 115.6 kW maximum output and 107 Nm maximum torque. | The brochure figures are regional and model-year-specific; check the local specification sheet for other details. |

Honda CB650R: the smaller-displacement option
The CB650R is the smaller-displacement inline-four in this shortlist. Its regional brochure lists an unrestricted 70 kW version and an A2 35 kW version, making it worth considering for riders whose licensing rules or power preference call for a restricted option. Confirm that the relevant version is sold and approved in your market.

Honda CB1000 Hornet and Hornet SP: distinguish the trims
The standard CB1000 Hornet and the SP are separate versions, not interchangeable names for one specification. In Honda’s 2025 regional brochure, the SP has higher listed maximum output and torque than the standard model. For the 2026 US SP, American Honda lists a 465 lb curb weight, 31.9 in seat height, 4.5 US gal fuel capacity, Öhlins rear shock and Brembo Stylema front calipers. Those are 2026 US figures, not a global specification or a direct conversion of the regional brochure’s numbers.
American Honda’s 2026 CB1000 Hornet SP specification release is dated January 7, 2026, and states, “Specifications subject to change.” Check the latest local information when comparing listings.

What about the Suzuki GSX-S1000 and Kawasaki Z900 SE?
Both appear in published comparisons with Honda’s CB1000 Hornet SP, but the cited material is editorial comparison coverage rather than a current manufacturer specification sheet for each bike. Cycle News describes the CB1000 Hornet SP and GSX-S1000 as 1000cc inline-four naked bikes. The MotoPlus comparison includes the Suzuki and Kawasaki alongside the Honda. For the GSX-S1000, confirm the exact model-year engine, equipment and availability using Suzuki’s official information for your market.
Do not assume the Kawasaki Z900 SE belongs in a four-cylinder list without checking Kawasaki’s official specification for the specific year and market. The cited comparison is not itself a manufacturer confirmation of the bike’s cylinder layout.

How should you choose between four-cylinder motorcycles?
Cylinder count tells you the engine layout; it does not tell you whether a bike’s weight, ergonomics, performance or equipment will suit your riding. Compare versions sold in the same country and model year, and focus on the details that affect how and where you ride.
- Power and delivery: Compare output figures from the same market and model year, and distinguish unrestricted models from restricted versions such as the CB650R A2 variant.
- Weight and fit: Check whether a published figure is curb or kerb weight, then assess seat height and the bike in person if possible. Figures from different regions may use different units and conventions.
- Suspension and brakes: Compare the actual equipment fitted to each trim. The 2026 US CB1000 Hornet SP release, for example, names an Öhlins rear shock and Brembo Stylema front calipers; do not assume those details apply to other versions.
- Everyday use: Consider riding position, fuel capacity, passenger needs and the type of roads you use. A higher-output engine is not automatically the more practical choice.
- Local ownership details: Verify availability, price, service requirements and insurance costs with local sources; the cited material does not establish comparable figures for these items.
What do the comparison tests say?
In MotoPlus’s Dutch-market comparison of the Honda CB1000 Hornet SP, Kawasaki Z900 SE and Suzuki GSX-S1000, the Kawasaki scored 695/1000, the Suzuki 677/1000 and the Honda 669/1000. MotoPlus placed the Kawasaki first overall and for value within that specific test. These scores reflect that publication’s bikes, market and criteria; they are not a universal ranking or a substitute for checking the Kawasaki’s configuration before treating it as a four-cylinder candidate.

Read the MotoPlus comparison test. Cycle News also compared the 2025 Honda CB1000 Hornet SP and Suzuki GSX-S1000 in its September 2025 article; its descriptions and manufacturer claims are tied to that comparison’s model years and context.
Why this is not a verified list of ten bikes
The available evidence does not establish ten current four-cylinder motorcycles with comparable official specifications and market availability. A title promising ten should not turn comparison appearances into confirmed specifications or assume a model’s cylinder layout. The models above are a grounded shortlist, not a complete ten-bike ranking.
