2026 FIM World Sportbike Championship
Key Technical Regulations Released
The FIM has outlined the provisional 2026 technical regulations for the new World Sportbike Championship, defining a clear framework for the middleweight production-based category that will replace WorldSSP300 and sit below World Supersport and WorldSBK.


The new regulations confirm the class’s focus on balancing performance across various motorcycle configurations, including twin, triple, and four-cylinder engines, through controlled technical freedoms, balancing tools, and cost-capped componentry.


Engine and Performance Parameters
Machines will be controlled to produce approximately 90 hp, using normally aspirated engines based on FIM Phase 2 homologated production models (listed below). This gives riders around twice the power of the WorldSSP300 category that WorldSPB replaces.


Engine displacement must remain at the homologated bore and stroke; modification to meet class limits is not permitted.

All models must feature ride-by-wire throttle systems, either as OEM equipment or via an approved control kit.

Performance balancing will be applied through measures, including torque-limited mapping, rev limits, and minimum weights, which will be adjusted throughout the season based on data.


Weight and Balance
Minimum combined rider/machine weights vary by manufacturer, typically ranging from 235 kg for 600–700 cc machines to 216 kg for smaller-displacement models such as the Kove 450RR.

Weight compliance will be checked in parc fermé and during practice sessions, with ballast permitted for balancing purposes.

Combined weight refers to the total weight of the rider in full gear and the motorcycle. If the bike has achieved or exceeded the ‘Soft Maximum’, then the combined weight does not need to be reached. The bike alone must never drop below the stated hard minimum weight.

WorldSPB Weight Table
| Model | Hard Min | Soft Max | Min Bike/Rider |
| Aprilia RS660 | 160 | 170 | 235 |
| CFMOTO 675 SR-R | 160 | 170 | 235 |
| Kawasaki 636 | 165 | 175 | 240 (TBC) |
| Triumph Daytona 660 | 165 | 175 | 240 (TBC) |
| Yamaha YZF-R7 | 160 | 170 | 235 |
| KOVE 450RR | 141 | 151 | 216 |
| Suzuki GSX-8R | 169 | 179 | 244 (TBC) |
| Honda CBR600 | 165 | 175 | 240 (TBC) |

Control Electronics and Data Systems
The Mectronik MKE7 (part number MKE7–WSS600_A) control ECU and 2D Sportbike dashboard are mandated, with price caps of €2016 and €990, respectively.

Firmware must be FIM-approved and updated with the official “FIM Settings.”

Only approved sensors and CAN-bus data loggers may be connected; telemetry or wireless tuning is prohibited.

All machines must use the championship’s 2-way radio (RF) system for Race Direction communication.


Tyres and Fuel
Pirelli remains the official single tyre supplier.

Tyre allocations are limited to three or four sets per event, depending on race format.

Minimum tyre pressure is fixed at 24 psi, with pre-race grid checks enforced.

Only the official World Sportbike fuel may be used.


Suspension and Chassis
All forks, shocks, and linkage kits must be listed on the FIM Eligible Parts for Competition List.

Fork kits including all parts such as but not limited to cartridge, springs (1 set), adjusters, fork caps, blanking inserts, seals, bushes, but excluding oil and fitting, the price limit is €1250 (TBC) excluding tax.

Shock Absorber/RCU: For the complete shock absorber/RCU, including but not limited to spring (1 of), pre-load adjuster and length/ride height adjuster, the price limit is €1500 excluding tax.

One racing chassis kit (including triple clamps, upper and lower sections, and stem) per manufacturer per season is permitted, with a cap of €1,000. Likewise, a rear suspension linkage kit, where available, combining all required parts, will be capped at €1,000.

The eligible products from the suspension manufacturers must be available to all participants at least one month before the first round of the World Superbike season and remain available throughout the entire season. The products must be available within 6 weeks of a confirmed order.

Teams may not modify any part of the forks or shock absorber; all setting and tuning parts must be supplied by the Suspension manufacturer and available to all teams/riders. These parts shall be available for immediate delivery to all teams/ customers.

Electronically controlled suspension systems are banned, even if fitted to the production model.


Braking and Wheels
Steel brake discs up to 320 mm diameter are allowed; carbon components are prohibited.

ABS systems must be removed.

Wheel rim sizes are limited to 3.5″ front and 5.5″ rear, with inertia restricted to within 10% of the homologated wheels.

Bodywork and Safety Equipment
Fairings must retain the appearance of the homologated road model, though construction materials may vary within limits.

The lower fairing must hold at least 5 litres to contain oil or coolant in case of engine failure.

All motorcycles must carry a rear rain light, active whenever sessions are declared wet.

Electronics and Power Management
The regulations specify detailed control over permitted sensors, including throttle, MAP, wheel speed, air temperature, brake pressure and GPS.

Lithium Polymer (LiPo) batteries are banned due to safety concerns, although Li-ion and LiFe batteries with integrated management systems are permitted.

Homologated Models and Balancing
Initial eligibility includes models such as:
- Aprilia RS 660
- Yamaha YZF-R7
- Suzuki GSX-8R
- Honda CBR600RR
- Triumph Daytona 660
- CFMOTO 675 SR-R
- Kawasaki ZX-6R 636
- Kove 450RR
Performance balancing will be reviewed every three rounds using FIM data algorithms, analysing speed, torque delivery and corner performance.


Implementation
The 2026 World Sportbike Championship will launch under these provisional rules, pending final ratification by the FIM and Dorna WSBK Organisation (DWO). The regulations aim to create an affordable, multi-platform racing class that unifies existing mid-capacity production machines within one global framework.
