PATENT: Honda’s 2020 CRF250L and CRF250 Rally getting twin-spark engine design and internal upgrades


Patents from Honda show that the factory’s quarter-litre off-roaders (with some pretty decent on-road manners too) are moving to twin-spark tech for next year.

Outwardly, the bikes look pretty much the same as the current models but will come with two spark plugs instead of one and a new mechanical fuel pump and direct injection.

Twin spark helps the engine burn the fuel/air mixture more efficiently. The mechanical pump is going to reduce the amount of services needed on the bikes and the injection should increase ‘pep’ from the motor when the throttle’s cracked too. In reality, this is pretty much what you want from these bikes for the coming year – especially as these motorcycles are such massive sellers in Asia and emerging markers around the globe.
