The Gresini rider was airlifted to hospital with a small C7 cervical fracture and a broken right collarbone. The restart red-flagged again on lap 1 when Johann Zarco crashed at Turn 1 and tangled with Luca Marini and Francesco Bagnaia. Fabio Di Giannantonio passed long-time leader Acosta with three laps remaining in a 12-lap final segment to take VR46's first win of the season. Acosta's post-race criticism of the restart is the first published rider-versus-Race Direction safety-protocol dispute of the 2026 cycle. Bezzecchi leaves Catalunya leading Martin by 15 points after his sixth-place chequered-flag finish was reclassified to fourth on other riders' tyre-pressure and causing-a-crash penalties.Mon, 18 May 2026 00:00:00 GMTweekend2026-motogp-seasoncatalan-gppedro-acostaalex-marquezfabio-di-giannantoniosafety-protocolrace-directionaprilia-title-fightPaddock NotesThe only V12 in the field, the only entry not boosted: how the Valkyrie's BoP problem is also a race-to-road problemhttps://paddocknotes.net/articles/2026-laguna-seca-valkyrie-bop-asymmetry/https://paddocknotes.net/articles/2026-laguna-seca-valkyrie-bop-asymmetry/IMSA's April 28 BoP table favoured every GTP entry except one. The lone Aston Martin Valkyrie #23 is the only car in the class with a roadgoing twin and the only LMH on either side of the Atlantic running a 6.5-litre naturally-aspirated V12. What Laguna Seca actually tests is whether the bridge between top-tier prototype racing and the road car still holds when Balance of Performance pulls in the other direction.Wed, 29 Apr 2026 00:00:00 GMTrace-to-roadimsa-gtpbalance-of-performanceaston-martin-valkyrierace-to-roadlaguna-secaPaddock Notes
