The Michelin website says the tire will be original equipment on 2019 BMW R1250 GS's, available beginning January 2019. The truck that just delivered three 2019 R1250 GSA's to my dealer had two bikes with the Anakee III's installed (including my bike) and interestingly, the third 2019 GSA had the new Anakee Adventure tires installed.
