A motorcycle may have little direct appeal to women for a number of reasons: they have to straddle it; they cannot ride it while wearing a skirt; the seat is high; and the body is large and heavy.
Yamaha gave careful consideration to the reasons why women hesitate to ride motorcycles and developed the following features for the Passol.
1. A step-through body
2. A front cover
3. A forced-air-cooled engine
4. An oil bath chain
Because it incorporated these features and its main dimensional specifications were designed for women, the introduction of the Passol created an explosive increase in the number of female users.
To make the step-through vehicle concept a reality, the engine was reoriented so that its cylinders were vertical, and forced-air cooling was implemented.
This engine layout became the basis for the scooter engines that were developed from then on. |
