Fabrizio Corsi, Yamaha’s Product Comm Manager for Yamaha Italy states that Tenere 300 is a possibility if the demand for it is high. He points to the fact that small adventure motorcycles like BMW G 310 GS and KTM 390 Adventure are increasingly popular, and that they are ready to follow the trends set by their competition. For now, Yamaha is still under huge hype that surrounds their Tenere 700.
It took a while for the Tenere 700 to arrive to the US market. If Yamaha decides to build a Tenere 300, it would take a while for it to release on the US market. Nevertheless, we certainly would like to see a smaller-displacement adventure bike come from Yamaha. It would certainly sell well!
