Yamaha boss Lin Jarvis is confident that Bradley Smith can "show more" because he is yet to display his full potential in MotoGP.
The Brit, who recently signed a one-year deal, ended last season with five top-six finishes on the Monster Yamaha Tech 3 YZR-M1.
"Have we seen the best of him?" Jarvis told MCN. "I don't think so and I think he can show more. I think he has shown what he can do but he needs to do it on a more regular basis. That's up to him to improve, so we will see if that contract goes on into 2016."
The 24-year-old, who earned his first MotoGP podium finish at the Australian Grand Prix in October, has competed in the premier class world championship for two seasons.
