welbike Posted March 14, 2021 Share Posted March 14, 2021 The picture is just too bad too see anything recognizable! any chance of a better one? the rear suspension really hints to something postwar. Lex Quote Link to comment Share on other sites More sharing options...
windy Posted March 14, 2021 Author Share Posted March 14, 2021 Heres a better pic. Had a quick internet scan & the front end looks just like a 1939 Triumph Tiger 100 but I can't find any with a plunger rear end so far 1 Quote Link to comment Share on other sites More sharing options...
jenkinov Posted March 14, 2021 Share Posted March 14, 2021 It's hard to scale the bike ..but the grab handles at The rear suggest it was not a lightweight ..the rear suspension. Indicates probably post war...but the girders limit it's age ....even by the late 40s most large manufacturers triumph. Bsa.Norton matchless et c where switching to telescopic forks .... So gut feel is its a smaller manufacturer... Jenkinov Quote Link to comment Share on other sites More sharing options...
jenkinov Posted March 14, 2021 Share Posted March 14, 2021 From its location looks as if it's been used as a field bike and dumped ..the rear plunger is very distinctive but the tank looks as if it has a suicide gear change mount .. Plus the girders forks ...suspicious it's a bitsa .. Interesting conundrum Jenkinov Quote Link to comment Share on other sites More sharing options...
79x100 Posted March 15, 2021 Share Posted March 15, 2021 The heavyweight Webb forks and the style of the headsteady clamp really look Triumph...The 'three stay' plunger rear-end is unfamiliar to me..I suspect that it is a 1940s suspension upgrade. I'd say that it was pre-war Tiger 100 with upgrades but that the fuel tank doesn't belong on it Quote Link to comment Share on other sites More sharing options...
Ron Posted March 15, 2021 Share Posted March 15, 2021 Rik is right. The front end with ally brake plate is pre-war heavyweight Triumph T90-T100-Speedtwin etc. The rubber mounted bars head steady, front gearbox mounting and rear mudguard are all correct. But I have no idea about the plunger rear and the hand change tank. Is it for sale? Ron Quote Link to comment Share on other sites More sharing options...

windy Posted March 18, 2021 Author Share Posted March 18, 2021 Picked the bike up last night. Frame number has TF prefix which suggests its a pre-war Tiger 100. Odd thing is these should all be rigid frame afaik & this is a plunger. It also has a swingarm running through the plunger tubes, which seems unusual. 1 Quote Link to comment Share on other sites More sharing options...
welbike Posted March 19, 2021 Share Posted March 19, 2021 Good show! it must be a postwar modification, that was done a lot in Italy! Any history with it? Lex Quote Link to comment Share on other sites More sharing options...
jenkinov Posted March 20, 2021 Share Posted March 20, 2021 Hi windy Curious do you have the frame number . It may help us identify how the frame was built .The plungers are very distinctive and quite basic and bearing in mind the front forks modification wonder if this is a home engineered conversion.

jenkinov Posted March 20, 2021 Share Posted March 20, 2021 I have looked at the triumph TT and race bikes from 1946 but can't see any that feature this suspension but have found widely sold kits post war produced by Amen or Santee to modify bikes into a rear plunger with instructions... Triumphs suspension modifications followed race team modifications at such events as the TT senior . These bikes featured heavily in the magazine's of the time and whilst exciting to research i can't find this modification .... A second route the home engineered conversion shows the rear plunger looks very similar to plunger s made by Santee .. Jenkinov Quote Link to comment Share on other sites More sharing options...
windy Posted March 20, 2021 Author Share Posted March 20, 2021 Thanks for the research Jenkinov. The frame number appears to be TF700, which suggests its a pre war T100 Tiger 500? I don't have any history apart from the bike belonged to the guy I bought if offs late father, who had used it as a field bike, then sold the engine & stored the bike in their old chicken shed covered in cardboard. The bottom frame tube appears to be continuous from the plunger to the front of the frame, so I can't work out how a standard rigid frame could have easily been modified to take the plunger rear. However it might become apparent if the frame is cleaned up a little. Quote Link to comment Share on other sites More sharing options...
windy Posted March 25, 2021 Author Share Posted March 25, 2021 This old 741 engine fits a treat & should make a nice special. Might take me a few years to amass the other parts though 1 Quote Link to comment Share on other sites More sharing options...
welbike Posted March 25, 2021 Share Posted March 25, 2021 Bit high in the frame though? Lex Quote Link to comment Share on other sites More sharing options...

Lex I think the crank centre is about level with the wheel centres in that pic, but I could probably drop the engine a little more Quote Link to comment Share on other sites More sharing options...
