Gear Ratios (Close Ratio)

4th Gear 1:1                     unchanged

Advantage:

The first three gears have significantly closer ratios, making them perfectly suited for dynamic power delivery. This results in a noticeably sportier driving experience, improved acceleration, and optimal use of the torque band.

At the same time, 4th and 5th gears remain standard – ideal for relaxed cruising speeds.
