Sequential Gearbox in detail
The story
The sequential gearbox comes from motorcycles and motor racing: you do not pick a gear on a gate, you go up or down one step. You cannot skip a gear or miss a shift, which is why it rules the racetrack, where every tenth of a second counts.
What you'll see move
Work the lever: one click and the next gear engages. You see the forks slide and move the sliding gears along the shaft, and the path of the power switch to a different pair of wheels at each step, across all four gears.
