There have been articles published on the subject of the interface between the human and the machine, to my knowledge, since the middle of the last century when German aircraft engineers demonstrated the advantages of the reclining position over the prone position.

Fitting a Malossi CVT kit to an AN400K3

I've just been fitting a Malossi kit to my Suzuki AN400 Megascoot. The first stage is to remove the lower left body panel. This has an astonishing number of little plastic nubbins that hold it on. The foot rest rubbers also have a very large number of bits that plug into the bodywork and you have to get under them to reach some of the fixings. Eventually you get the bodywork off, and the next piece is the CVT air filter cover, and then the plastic CVT cover. That gets you to here.

The next piece to remove is the inner cover. This is ally and has two dowels that eventually get stuck, bottom right and top left. The cover has an outrigger bearing for the clutch mechanism. Sometimes the shaft spins in the bearing making a nasty screech at very low speeds. You can safely ignore this as I'm not sure how to fix it if it happens to your bike. With the ally cover taken off, we have this.

FF front suspension

Front Suspension for open cockpit, FF Single Track vehicles

Definition; “FF”

A single track vehicle with a seat base less than 20” above ground level at ride height, fitted with a seat back capable of supporting the rider. The front suspension should not be steered.

Application.

This applies to all FFs but is specifically relevant to 'agile' or 'performance' FFs.

Sources.

The history of vehicle suspension was enthusiastically plundered. “The Motor Vehicle” (Newton, Steeds and Garrett, ISBN 0-408-01082-7) is a good source for multi-track derived systems. Contact with early seventies Formula One cars was also instructive. Of the various systems bolted to motorcycles only Normans Hossack's system, recently appropriated by BMW and the system pioneered by Tony Foale, subsequently used by Yamaha on the GTS, bear consideration for road use..

Advantages of different types

Advantages of different types of FF Single Track vehicles

Definition; “FF”

A single track vehicle with a seat base less than 20” above ground level at ride height, fitted with a seat back capable of supporting the rider. The front suspension should not be steered.

Application.

The following applies to all FFs. It is intended to be chiefly useful to designers seeking to define the type which best meets their requirements

Sources.

The Quasar and Voyager projects both involved study of the 'performance envelope' of the FF single track to try to gain a picture of the full potential. Since those projects others have gone on the produce other examples of roofed FF's (BMW, Benili, Ian Peagram) and the Peraves Ecomobile represents an excellent example of full enclosure. All these vehicle appear on this site.
