2.1.1 Specifications Yamaha R7 BLU CRU Cup

The Yamaha R7 BLU CRU Cup is exclusively accessible for the Yamaha R7 from model year 2022 onwards, new or second-hand.

All motorcycles must comply with these technical regulations. In exceptional cases, the Yamaha R7 BLU CRU Cup organization may decide otherwise in consultation with the participant to allow them to start.

It is not permitted to participate in other classes or sessions during qualifying and race days with a Yamaha R7.

The Yamaha R7 BLU CRU Cup organization may grant exemptions in special cases.

It is not permitted to offer two motorcycles for inspection.

Random checks and spot checks may be carried out during race weekends. Any machine found not to be in compliance will result in a penalty imposed by the Yamaha R7 BLU CRU Cup organization.

2.1.1.1 Mandatory Parts

The Yamaha R7 must be equipped with the following mandatory parts, available through the official Yamaha Benelux dealer network. If a part from the mandatory kit is missing from the motorcycle, the rider will be penalized by the jury.

The following parts can be used optionally, in addition to the mandatory parts kit:

• Parts marked with YES must be obtained from the Yamaha catalog.
• Parts marked with NO can be obtained from the Yamaha catalog or purchased freely. If purchased freely, the part must be sound and safe. The judgment of a member of the technical officials of the organizer and/or the Yamaha R7 BLU CRU Cup organization is binding.

Note: Apart from the above mandatory and optional parts, it is expressly forbidden to make modifications or interventions to engine parts, electronics, and/or chassis elements not mentioned above, in order to increase the performance of the R7. The judgment of the Yamaha R7 BLU CRU Cup organization is binding.

2.1.2 Technical Inspection and ECU

Every motorcycle must have been on a dynamometer at Ten Kate Racing. Only original ECUs, modified by Ten Kate Racing, will be used. At Ten Kate Racing, a run will be made on the dynamometer to check and adjust the mapping so that all riders use the same mapping. The motorcycle will then be sealed.

If the motorcycle has not yet been sealed or unsealed, it must be presented for inspection again by the rider.

There are no costs for riders who have purchased a new motorcycle for the 2025 season from the Yamaha R7 BLU CRU Cup organization. In all other cases, the costs are borne by the rider.

A motorcycle not supplied by the Yamaha R7 BLU CRU Cup organization is permitted, provided it complies with the regulations.

Unsealing of the motorcycles is only possible at the rider's request to the Yamaha R7 BLU CRU Cup organization. Unsealing must only take place under the supervision of the Yamaha R7 BLU CRU Cup organization or a member of the organizer's technical officials.

Any violation of this procedure will result in a deduction of championship points, earned from the moment the motorcycle is unsealed. In case of doubt about the moment of unsealing, the decision of the Yamaha R7 BLU CRU Cup organization is binding.

At any time, motorcycles may undergo a spot check on the dynamometer or a technical inspection. A detected technical violation of a machine will lead to a penalty, which may include the forfeiture of all championship points, depending on the detected offense.
