A 250 I4. That's 62.5 displacement per cylinder. That's gotta be super oversquare to get a spark and 4 valves on a chamber that small. Maybe it's two valves. Should be really popular in places with tiered licensing. When I lived in Japan, there were a lot of 18 year old boys riding 100cc machines styled like WorldSBK.
