It has been revealed that Yamaha will serve as the exclusive engine supplier for the Moto3 class starting in 2028. Replacing the current single-cylinder 250cc, the company will develop a new-generation machine based on a 688cc CP2 parallel-twin. It marks a major turning point for the class that serves as the entry point to next-generation Grand Prix racing.

Moto3 is the gateway for young punks chasing the world stage. And now Yamaha's taking sole charge of the engines there, based on a 688cc twin no less. The high-pitched single-cylinder world is about to change — for someone like me who clawed his way up from the lower classes, that's a genuinely moving overhaul.

A path where young riders develop on Yamaha engines, that's exciting.

If it's CP2-based, nice that the tech trickles down to production bikes, it's from the MT-07 lineage.

A sole-supplier setup means no competition, would it actually be exciting as a spec-series race?

From a 250 single to a 688cc parallel twin, that's more than double the displacement, basically a different class entirely.

So Moto3 goes to two cylinders. Sign of the times, I loved that high-pitched single-cylinder wail.

688cc, isn't that pretty large for Moto3...?
