Triumph has announced it will push the envelope of the triple-cylinder engine it supplies to the Moto2 World Championship by increasing performance for the 2023 season.
The British marque is in the fourth season of its tender as the control engine supplier for the Grand Prix World Championships intermediate class using the 765cc three-pot derived from the Triumph Street Triple RS.
Taking over from Honda - which had supplied the class with a 600cc engine from its inaugural season in 2012 - at the start of the 2019 Moto2 season, Triumph’s engine represented a step up in performance over its predecessor for the category, as characterised by 68 new lap records being set since.
With the engine being widely praised by riders competing in Moto2 for its flexible power band, Triumph has also won acclaim across the paddock for the 765cc engine’s reliability having experienced precious few significant breakages in three full seasons.
It is for this reason that Triumph will push to get 5 PS more from the engine ahead of the 2023 Moto2 season, while it will also up the revs by 400rpm.
“The latest developments further improve the top end of the engine, increasing compression ratio with a new cylinder head, longer valves to increase lift along with a new camshaft profile, and revised valve springs,” Triumph confirmed in a statement.
“To maintain the engine’s impressive reliability record, having already completed nearly one million competitive Moto2™ kilometres, further improvements focus on the pistons, conrods and crankshaft to cope with the higher piston pressure of 90 BAR (up from 85 BAR).”
Announcing the developments ahead of this weekend’s British MotoGP at Silverstone, the company also confirmed the Triumph Triple Trophy will continue to run alongside Moto2.
Having changed its metric for 2022 by awarding points for best race progression from starting position to finish, the engine tweaks tie into this through the hope of providing more overtaking opportunities.
