When it is pondered to create and to develop a prototype, there are several decisions that had to be taken, in conscience, after a long and recommendable reflection, based on the nature of the end item that if it intends and on the available ways to conceive it.
Everything this, having as deep cloth of the acquired and existing knowledge, to all the levels, that are the base of everything this. Of this mix/cocktail, it will start to appear the sketch of the specifications that the machine will possess.

Conception of the type of preparation that if it intends, in function of the following parameters:

Mechanical characteristics of the existing materials/Spare Parts in the Portuguese and International market, or either, special parts that do not equip any standard/stock model, but that they are conceived to improve these models. (WISECO forged pistons, Hot-Rods connecting-rods, new head domes with different combustion volumes, etc)
Knowledge of the specific characteristics of the materials that equip the available motorcycles in the market, given that these motorcycles exist in the market, and the respective components are sold in the market of spare parts.
Levels of Resistance of these same materials; we can have information if we know the characteristics of these materials and motorcycles where they apply, to be able to survey with some reliable level its resistance to the loads we intend them to be subject.

Global available budget.
Character of the end item.
Persistence.
Work.
Organization of the tasks to play, to maximize the efficiency of the same and the project management to avoid the project to become a nightmare.
Varied Contacts. Good relations.

We think, that using this method and respecting all the main objectives, it's possible to create an unique prototype and the probabilities of sucess in all levels are very high.
