The new spec engine, with its redesigned piston crowns, updated valve timing, and redesigned airbox with two intake ports, instead of one, boosts peak horsepower to 80.55 at 11,000 rpm. Even more impressive is the CB’s flat spread of torque—especially for an inline-four middleweight. It jumps off the corners well and the engine also sounds a tad beefier than we remember, with a more pleasing airbox note. The engine also revs to 12,900 rpm, 1,000 rpm higher than before.
