Comments on: Moto Guzzi W103 – 3 Cylinder V-Triple Motorcycle Engine http://thekneeslider.com/archives/2009/08/11/moto-guzzi-arrow-w103-3-cylinder-v-triple/ Motorcycle News for Positive People Sat, 26 May 2012 00:02:46 +0000 hourly 1 http://wordpress.org/?v=3.3.2 By: Klaus http://thekneeslider.com/archives/2009/08/11/moto-guzzi-arrow-w103-3-cylinder-v-triple/#comment-298747 Klaus Tue, 04 Jan 2011 15:14:48 +0000 http://thekneeslider.com/?p=7315#comment-298747 As intersting as it looks, I'd say they had their reasons why they never built it. Why add a third push-rod, 2 valve, air-cooled cylinder which forces the engineers to come up with major changes? Kind of reminds me of the Triumph triples, too little too late. Why not update the engine to DOHC, with 4 valves, watercool it and give it higher compression. Or like ONMAG suggested, supercharge it. There is no letter in our alphabet for this kind of triple or for Bugatti's engine configuration. W comes close and people know what it stands for but it suggests four banks and two cranks, like two Vs would have. And that would be one crank too much. And anon, you wrote: "in German, the letter “W” is called double V", that's not the case. In german, the letter "W" is pronounced like the english "V", and the "V" is pronounced like an "F", but who cares. As intersting as it looks, I’d say they had their reasons why they never built it.

Better that than the new sci-fi design. As an entusiastic Guzzi Rider, I would love to see the Arrow engine in production. Better that than the new sci-fi design.

Part of Tonti's inspiration maybe harkened back to the old Cecil Sandford 120-degree Twin [plus +one] using the Guzzi small-block cataloged bits that were calling to him to make a Triplet. http://www.google.com/search?hl=en&q=life+w12&aq=0s&oq=%22Lifa+W12&aqi=g-s2 Maybe have a look at the LIFE W12 to see something similar to the above discussion.

Note that the head on the central cylinder is different. I think the sump may be deeper too. Kenny - some bikes have had the pipes flowing over the top of the cylinder but it isn't common. I guess I wouldn't want to have a hot pipe running that close to my knees. I rode a Guzzi for some years and having a hot cylinder next to my knee was all the heating I needed!
