The third volume is devoted to Moto Guzzi. There are articles about the "Normale" distribition, "Condor", "Dondolino" and "Gambalunga" performances and flow and hp bench test of a "Falcone" engine. All results are published. Moreover, an estetic study of a Moto Guzzi "Falcone" and a reportage about the Moto Guzzi Classics Club of Schio (Italy) visit. The tuning of Mr president's Guzzi Falcone!


This website, whose birth is datable in July 2007, represents an activity of study, analysis and researchs of the techniques of the past years. The team is an association of technicians, impassioned and supporting; they try to find the "roots" and the "reasons", using the modern methods but also comparative with the classic ones. The target is to find the performances and constructive reasons that were generally adopted in the automotive sector both bikes and cars.


For these reasons, we have materials like historical books, technical handbooks, original plannings and many others; moreover, this association has also a very conspicuous and "strange" modern technology to study the part. In fact the main  sponsor of this project is the SOFT-ENGINE company, leader in the dynamometers, flow benchs, camshaft and engine simulation software manifacturing and many others.


The union of all this offers us the possibility to do an analysis detailed of the engine and of the vehicle through the re-planning of it and also to understand the reasons and the solutions of the ancient projectist.

In this optics, we have involved the Università Politecnica delle Marche with which we make jobs of search in the historical sector.


Mainly, the job develops on "Moto Guzzi" engines and it is really curious to produce thesis of degree about the study of "Dondolino" a connecting rod or a "Sport 14" shaft with tubular connecting rod with with metal bearing. 

All this doesn't deceive the reader: the job develops only with the most sophisticated technology, but in the more part of the cases the planning are made with the ancient mentality, by classic books and methods of that period.




We want immediately to specify that we don't intend to invade the experts fields, neither we have velleity historic or documentaristic, (only to know the truthfulness of a solution and the originality of a made a tested part). Moreover, we don't invade the field of the collectors too, renovators and of the replicantis, on the contrary we need their help and we accept well gladly the consultation and possible material that there is still lacking. 
So, we already thank some persins and structures, like the Mr .Zaghini partner of the Museo Nazionale del Motociclo (Motorcycle Museum) of Rimini that has understood and enthusiastically sustained since the beginning our initiative furnishing us precious information and material and several other persons that have stuck in the last years fantastically to the idea free collaborating to find pieces, documentation or to feel near the last witnesses (ancient mechanics) if they remembered something of as made a part or where was climbed on. This type of people has made us understand that the road undertaken of the enthusiasm and of the passion is that correct. 
Lately fan is added, friends and impassioned above all in the italian region Marche that the CMAJE of Jesi (AN - Italy) crosses lavish him to make to grow this project.

Now, very important people for classic engineering collaborate with this project, that was born very well.


Obviously this is an extremely specific activity and it will be rare to interest even someone from data about the flow coefficient of "Sport 14" engine (how the engine "breath"), the maximum pressure in the cylinder or a Guzzi "Falcone Sport" valve acceleration! But we will answer to these kind of questions: "Was there need of such a heavy flywheel"? We answer this question, for example, by calculating the degree of irregularity of that engine. What is the final purpouse? Surely that to discuss about technical curiosity, because nobody today can do it and the research of such answers is our main purpouse. Also, we like to nostalgically relive the motoristic "verve" of that almost pioneer years. It is certainly an illusion to relive the past propitiouses, almost he was inside the pulsating heart of a cylinder: while the common impassioned people (we also do it!!!) drive a motorbike of the thirteens and does it turn for the countries dreaming to be still in that years. Our nostalgic idea is mainly , about technical subjects; means test a flow capacity about cylinder head a "Moto Guzzi Sport 15" or testing the horsepower of a Gilera or a Guzzi to the bench....


A dynamometer test session is begun, prepared especifically for motorbikes "Moto Guzzi 500cc". A series of tests for different models, different configurations and types.


An interesting perspective is that to make service activity for people who have a motorcycle or sporting auto or for who participates to race classic competitions and want to try or to tune their motors, and obviously for testers; in a second time some "specials" can born by those studies


Natural epilogue of this kind of activity is surely the production of a documentation born by these studies. In fact, it goes out the first volume about the studies that partly are published in the site ( It is a periodic publication; in the first volume of “THE HANDBOOK OF CLASSIC ENGINEERING”, mainly devoted to Moto Guzzi, we publicate dynamometer tests, not easily available on other texts, of Moto Guzzi Falcone with different configurations of camshafts and exhaust system and results in comparison. But not only: we publish monographs on the run models Condor, Dondolino and Gambalunga, with unpublished "exploded" plannings and design and photographic documentation.


The following step is the realization of a complete race engine models like Condor, Dondolino and Gambalunga; we have made the fusions for carters and we are going to complete the entire motorbike. 


The engine of Condor, Dondolino e Gambalunga is made. We built all the motorcycle parts like engine, chassis discovering ancient ways to make the mechanics parts. Finally the complete motorcycle chassis is done, and it is a big emotion to see the motorcycle on the road (see the video).


The "Condor" planning is done now, and this motorcycle, eneterely an "Ingegeneria d'Epoca" manifacturing, was already tested at dynamometer and on the track. There is a very nice new video showing this...


Our works continue with the next model, "Dondolino", actually work-in-progress. It was presented in the "Novegro 2016" expo.


During 2016 we found the engine C2V 1926, the first racing bike Moto Guzzi, we are going to restore and tune it with our full competences.


We finally confirm the thanks for all those people who want to collaborate furnishing data suggests, criticisms and technical and historical precise statements... they are welcome ones.
