Aprilia and Ducati confirmed in a pre‑Indonesian Grand Prix briefing that the 2027 850cc MotoGP power‑unit transition remains a cost‑heavy gamble, yet early data show lap times still rival the 1000cc packs.
Engine size versus lap time
The CEOs acknowledge that the difference in horsepower—about 50 less on the new bikes—has yet to dent average lap times, which line up with 2026 1000cc figures.
Accidents at Mugello demonstrated that straight‑line velocity may drop, with Marco Bezzecchi and Jorge Martin reaching 368.6 km/h, but corner entry speeds appear unchanged.
“We’re seeing the same pace, but the power drop will trim top speed,” Massimo Rivola said, pointing to the timetable of the forthcoming switch.
Safety focus and rider feedback
Gigi Dall’Igna emphasized the primary safety benefit: the reduced approach speed to corners should mitigate the risk of high‑impact incidents.
He noted that riders report the 850cc machines feel easier to manage, hinting at potential rider‑comfort gains even if lap times stay comparable.
“Even a modest power reduction can translate into a safer race line,” Dall’Igna remarked, underscoring the team’s strategic vision.
Tire dynamics at the heart of the debate
Pirelli’s upcoming role as sole tyre supplier offers the only adjustable lever to fine‑tune performance for the 2027 season.
Rivola highlighted that tyre behaviour remains a key determinant of cornering ability, perhaps more so than engine capacity.
“A tyre fit can either amplify or counteract the power drop, so we expect a recalibration effort,” he added, pointing to the evolving performance envelope.
With the new tyres scheduled to alter grip profiles, the 850cc experiment may ultimately redefine how close racing margins can safely close.
