American beverage brand Monster Energy became the team's main sponsor in 2009 and the team's name was thus changed to Monster Yamaha Tech 3. Its YZR-M1 bikes were adorned with white and fuorescent yellow graphics, including Monster Energy's three claw mark logo, on a black-colored body, a livery which stood in sharp contrast to the two-tone Pearl White and Metallic Blue works team machines.

Responding to new regulations which designated Bridgestone as the sole tire supplier, the 2009 YZR-M1's design incorporated a number of improvements to enhance its potential. Despite not being familiar with the Bridgestone tires, Edwards quickly grew accustomed to them and consistently earned points. His performance at Rd.10 British GP, which began in nearly dry conditions but turned into a wet race, was particularly notable. It was a race in which the fag-to-fag rule, which allows riders to switch to bikes with more appropriate tires in accordance to weather developments, was implemented. Despite having qualified in 6th place on the starting grid, Edwards rode tentatively in 15th place during the early part of the race due to the tricky track surface conditions and his selection of slick tires.

However, he was able to discern the surface conditions and make his way up through the field.As other riders entered the pits to change bikes, Edwards stayed on his slick tires, rising to 5th place by Lap 20 and 3rd place by Lap 23, setting the fastest lap time in the process. Edwards went on to dramatically clinch 2nd place with an overtaking maneuver at the final corner on the final lap. His performance helped the YZR-M1 place a rider on every race podium during the season for the second year in a row.
