The Tokyo Motorcycle Show wrapped up this weekend, but the Mugen Shinden Nana isn’t the only surprise that the Japanese brand has in store for us. Mugen also debuted this interesting engine concept.
Mugen is pretty tight on details, but word out of Tokyo is that this is a 1,400cc, four-valve, air-cooled, push-rod motor design that Mugen is considering putting into production as a crate engine for bike builders, with a delivery date somewhere in 2020.
