Loris Capirossi said on the Mig Babol podcast that the new 850cc bikes are expected to be up to about 2.5 seconds slower per lap than the current bikes, especially at the start of the new rules era. This information comes from early data and predictions, but it has not yet been proven on full race bikes.

The engine size will drop from 1000cc to 850cc under the official plans, which has been confirmed by MotoGP organisers.

The rules will also ban ride height devices and holeshot systems, and reduce the aerodynamic parts on the bikes.

From 2027, Pirelli will replace Michelin as the official tyre supplier in MotoGP. This change is widely reported and is part of the new era.

Several teams, including KTM and Honda, have already tested early 850cc engines, but this is still part of development before the 2027 bikes start racing.

Many fans believe the exact loss in lap time does not matter so much. They want better and more exciting racing rather than just faster bikes. This opinion comes from online fan comments and discussions.

Safety is a key reason for the change. Reducing top speed and technical complexity is part of the official goal.

At this stage, the prediction of the bikes being 2.5 seconds slower is only an estimate. It is based on early engineering data and expert opinions, not on final race performance.
