All that is definite so far is that the XT660 engine will NOT pass Euro 4 emissions regulations. So we can safely assume (as your contact probably has) that it's highly likely that that the sole remaining XT660 on the books, the Tenere, will end production within the next year as Euro 4 will be rolled out from 1st January 2017. As a result of Euro 4, bike emissions will be tested for the MOT from from 1st January 2018 (although all pre 2017 bikes will just require a "visual" emissions check as is currently the case.)
