About Yamaha Majesty Motor Scooter These motor scooter represents the 2nd generation by high-tech scooter product.

1st generation motor scooter* admitted the Honda CN250 Space, and the Piaggio Hexagon. A basic, decisive trouble on this 2 motor scooter* was the front dangling system.

Neither has an classical hydraulic fork, just an duple (CN250) and an individual (Hexagon) swingarm scheme. This systems we are able to allow quite good comfort on riding. Just the trade off was a unsteady feel, particularly once the sidewalk was not gross (and once are them ever?). And so Yamaha chose to give their new motor scooter an bike feel by installing an conventional front telescopic fork, by on a big disk brake and four-piston caliper that feeds you secure braking. To accomplished these opera, a few big tires were fitted: 100/90 front and 130/70 rear. Wheel diam expanded too, to a banging 12.0 inches.

Another trouble on motor scooter* that Yamaha’s engineers attempted to solve was wind blast on the passenger. They have redesigned the entire bodywork, and you can see the effects in the picture. It looks attractive enough, and reminds one and only by the front side from touring cycles like the BMW R1100 RT, and offers good security to wind and rain. The similarity to an BMW is not restricted to apperance. Considering the stated maximal accelerate (more than 126 kph), you are able to do some short touring, also. A trip by approximately 400 Km in one day wouldn’t be out of the question. There is a lot other chill features included on these motor scooter too, such because the seat, which opens toward the front and are held open by an hydraulic piston chamber.

The law of similarity to an BMW isn’t restricted to apperance.

Below is the engine specifications. Yamaha, in this case, has not presented anything advanced. They have chose to stay on an conventional 4-stroke liquid-cooled individual that should provide reduced service time interval*. Course, the robustness of the transmission scheme needs testing – a critical arena in these kind by automobile, particularly as ability are considerable.

3rd genesis motor scooter*

Yamaha is moving motor scooter* advancing to a new genesis. As in the calculator world, where as soon as a new automobile are presented to public it has at once replaced by the next example, we prefer to try and define the requirements for the 3rd genesis motor scooter: Increasing wheel diameter to more than XV inches (better sixteen inch) Increasing the frame’s torsional strength Increasing the diameter of the front fork Increasing the power and displacement of the engine (and of course the torque too) Increased power may cause a few troubles to the transmission system, so it might be essential to devise a new scheme like the electronic/hydraulic sequential gear change system used in F1 racing and in a few Porsche product examples. Adding an rear disc brake Refining the wind/rain protection and the CX. With all of the above items incorporated into the next generation scooter, you would have a machine with good ride feeling, a satisfying cruise speed (around 140 Km/h), and good speed performance (max speed greater than 160 Km/h, quick acceleration, etc.). We hope another manufacturer would soon enter the challenge, which would stimulate competition, and help shorten the arrival time of the ultimate Third Generation Scooter.
