Yoshi go Alpha for new MT-10
Yoshimura effectively have two independent operations that come together under the same umbrella organisation. The Japanese factory is responsible for exhausts sold in the home market as well as Europe, so it makes Euro-complaint kit. The California factory makes exhausts for America so those meet their standards. That often means two different Yoshi exhausts for the same bike, made in different countries to different standards. But both the American-made and Japanese-made are imported to the UK by the same firm. So if you really want a road-legal Yoshi exhaust for an MT-10, just wait a while for the Japanese arm to produce their version. It’s not made it to market yet because Euro testing takes longer.
