That is because its a big cruiser. The power is put middle to top for highways. Even at that it turns the 1/4 1.5 seconds faster than a Speedmaster in the low 13s. Granted we can't compare them to our much smaller bikes.
The Scout being a smaller cruiser performs really well with acceleration in the 12s and reasonable clearance for a cruiser for a twisty. That really modern motor does not look good in that that retro scheme they have going on for the original post.
