Super Tigre classics

Calling all aficionados of Italian engines!! I’m currently working on getting started on a history of Super Tigre’s classic era (from the start up to the early 1960’s). I have assembled a fair bit of information, but I’m going to need help from better-informed sources to get this done!

One area of confusion arises with the 5 cc Super Tigre G.21 series. I gather that the original ring piston version originated in 1951. I need to know when the first lapped piston models appeared. I also know that the lapped engines came with shiny cases (as illustrated) and with matte cases as well as separate backplates secured by four screws – I need to know when those changes occurred.

Another area where I’m lost is with the G.25 diesel of 1 cc displacement. I believe that the first model with integrally-formed cooling fins originated in 1954,, but there was a later version (illustrated) with a separate aluminium alloy screw-on cooling jacket. I need to know when that change was made.

Can any kind reader help me here?

This thread is of course open for any and all discussion relating to Super Tigre engines.  I may have more questions myself!

  1. I’m excited to see this development. I have a small collection of vintage Super Tigre RC engines. I see that early on there were several carburetor changes and also a development of the crankcase castings. Would love to see an analysis of all the “V” engines and previous lines too. Was this the era of escapement RC and 3 line U control carrier events? I wonder. Thanks as always, Paul V Thailand

  2. Aaaand, I’m wondering, what was the very first Super Tigre throttled engine please? Was there any thing before that in Italy such as the Vivell ignition with choke throttle accessory as per United States scene? Thanks, Paul

        The only ignition ST of that displacement of which I’m aware is the G24 of 1953-56. It’s actually a rear drum valve racing 60. Is this the engine to which you refer? It’s covered a little in my article on the classic Super Tigres. Most of them were glow-plug, but they did make a few ignition versions like the one that I have.

  3. I also have a lapped .29/5cc Super Tigre Model G21 from that era and it looks just like the one in your picture except the intake sleeve blanks off the holes drilled for NVA and the front of the intake boss is now drilled for NVA. It has a serial number on the side of the right lug and it is 1264. One of the back plate screws is replaced with an Allen Screw and another has a pressure take off fitting that may or may not be original. The exhaust outlet casting has a mild curve ground into it so this too may be a modification. I hope this helps some. Thanks, Paul

  4. Hello! You make a wonderful work for the History of our passion. About old ST engines and specially the 21/29, i can try to have some details from one of my friends, André Nougier (french speed champ .15 and.29) He don’t speak english, so i need precise questions to made translations) A detail, his father was Jean Nougier builder of racing Nougier motorcycles. Pierre

    1. Thanks for this, Pierre! I was also a racing motorcyclist, and I heard of the Nougier motorcycles, although they were not very common in England an (later) Canada when I was racing. I never actually saw one.

      I’d be interested to learn how the Super Tigre engines compared to the Micron racing models. Did Andre use Super Tigre engines because they were faster than the Microns? Also, in what years did he win his championships?

      Thanks for your interest!!

      Cheers,

  5. Hi, timing permitting, I practically have all the rare engines, if we don’t consider only the Super Tigre brand, Jaures Garofali made other spark engines before the G24, including the 37 G1 made in 18 years of which I have an original and the G9 of which I have the reply etc. etc. I wanted to have email contact with Adrian if possible
