On fire! Our new Throttle Up lets r' rip with unforgiving power and control, createing pin action that's a gas! It's what you'd expect from the high-speed, polished MuscleGT coverstock. And that's just for starters. The Cam Shaft core fuels the flames with a higher Rg (2.52) and lower differential (0.048) to rev later down the track. Face it. Throttle Up dominates the road, exploding straight down the middle with its eyes on the prize. Competition's in the ashes.
