Fuel Flow Adjustment for BMW and Ducati – Checkpoint 3 Implementation
After the latest Concession Checkpoint (Checkpoint 3), the FIM has determined that both BMW and Ducati have exceeded the performance threshold. This is defined in Article 2.4.3.2 of the regulations. As a result, both manufacturers will now face a revised Fuel Flow penalty.
In accordance with the newly introduced linear penalty algorithm (in place since Checkpoint 2), BMW’s and Ducati’s Performance Threshold values have surpassed the limit. This triggers an increased fuel flow restriction.
Specifically, both manufacturers will now receive a Fuel Flow Limit penalty of 1.5 kg/h. This is raised from the previous 1.0 kg/h, reflecting a stronger overperformance relative to the balanced field.
The updated system replaces the former step-based model with a proportional, continuous scale of penalisation. Penalties are applied linearly between -0.250 and -1.000:
- Minimum penalty (-0.250): 0.5 kg/h
- Maximum penalty (-1.000): 1.5 kg/h
- Formula: Fuel Flow Penalty = Performance Threshold × 1.5
These penalties are cumulative and remain in place unless recovered through improved relative performance, as defined in the same article.
BoP Update for Yamaha in Supersport Next Generation
In the Supersport World Championship, Yamaha’s performance over the last six rounds has been consistently above the competitive average. Following the mid-season review as per Article 2.5.3.1 – Balancing Calculation, and considering the manufacturer’s recent swingarm update request, the FIM has taken further balancing measures.
Effective from the Donington Park round this coming weekend, the Yamaha YZF-R9’s hard minimum weight will be increased. It will move by 5 kg, going from 161 kg to 166 kg. The updated BoP parameters are as follows:
| Brand | Hard Minimum Weight | Soft Maximum | Combined Bike & Rider Minimum* |
| Yamaha YZF-R9 | 166 kg | 175 kg | 244 kg |
This adjustment is made in accordance with Article 2.5.3 – Balancing Various Motorcycle Concepts. It is aligned with Yamaha’s agreement to accept future technical modifications.
This agreement is if any performance gain was observed post swingarm change.
Despite the unchanged engine performance figures, overall competitiveness improvement necessitated this revision.
