Description

● YUMINASHI 4-SPEED CLOSE MISSION ASSY. (12V GB2 / GB4 / GB5 / GB6 ENGINES) (23511-12V-4SP)

● The 4-Speed close mission kit has been developed to change the stock 3-speed transmission or your stock 4-speed transmission into a sports 4-speed close mission transmission and this for the 12V 50cc, 70cc, 90cc, 100cc and 110cc engines with the kickstart sprocket included in the set.

● A 4-speed gearbox on a Honda motorcycle offers better fuel efficiency and a wider range of speeds, allowing for more both relaxed cruising and better acceleration, compared to a 3-speed gearbox, and the 4th 22/22T sports gear makes it much easier to gain top speed compared to an overdrive.

● Here's a more detailed breakdown of the benefits:

Fuel Efficiency:
The extra gear in a 4-speed gearbox allows the engine to operate at a more optimal RPM (revolutions per minute) range, leading to better fuel economy, especially at higher speeds.
Wider Range of Speeds:
A 4-speed gearbox provides a greater range of gear ratios, enabling smoother acceleration and a more relaxed cruising experience.
Improved Acceleration:
The 4th gear can be designed to have a lower numerical ratio, which allows for quicker acceleration without the engine over-revving.
Reduced Engine Noise and Wear:
By keeping the engine RPM within a more efficient range, a 4-speed gearbox can reduce engine noise and wear, especially during long highway rides.
Better for highway:
A 4 speed will have taller gears that require less shifting around town. While they do almost always have a lower top speed, they're often quicker than their 5 speed counterparts

● GEAR COMBINATION:

G1: 14-31
G2: 18-27
G3: 20-25
