Bahattin Sofuoglu brought the name made famous by his cousin, five-time WorldSSP champion Kenan Sofuoglu, back into world championship motorcycle racing in 2018, making a Wildcard appearance in the FIM Supersport 300 World Championship and going on to participate in eight races the following year.

In 2020, he joined Yamaha's bLU cRU program, racing for the Biblion Motoxracing Yamaha WorldSSP300 Supported Team. Sofuoglu won on his first weekend of the season, following fellow bLU cRU rider Unai Orradre's Race 1 success with victory on Sunday.  

The Turkish rider won from pole position at Aragón, stepping on the podium again that weekend with third in Race 2. Sofuoglu scored another top-three finish at Magny-Cours and ended the season third in the championship as the top Yamaha racer.

In 2021, he is contesting another WorldSSP300 year as a bLU cRU rider, and will look to convert his rapid pace into race victories to mount a serious championship challenge.
