The Foster "Otters"

 The start of the journey.

 

    *************

 

 

Built By Harry Foster

 

 

 

This Harry Foster BSA "Otter" now lives in Spain? I would like to here about the history of this bike.

 

 

This is the man that started the History of the Now Famous BSA "OTTER"

 

Harry Foster. riding his International Trial Triumph.

 

 

This smart "Foster Otter" lives in Austria or Germany, I am trying to get the story!

This is Mark Griffiths "Foster Otter".

Mark Griffiths, has sent me more details about this bike. this is what he said.

We keep finding the "Foster" bikes don't we.

 

Hello Charlie.

The frame is an original complete with 'Otter Product' sticker on the headstock.

Engine is WD GB alloy barrel, trials gearing etc.

I bought the bike locally from a friend of a friend, was in a bad state, bent valve/broken guide; wrong length primary chain; dodgy fixings everywhere; leaking fuel tank etc etc.

I've rebuilt the top end, fitted new tank, new fork yokes, bearings and seals everywhere!

New sump guard, footrests, bars, alloy clutch, exhaust...too much to remember!

Runs well now, I've ridden it in the last couple of Bonanza trials with no trouble whatsoever.

Regards Mark.

 

From 2010 start of the BSA Otter web site

 

Now that the story about how the "Otter" was born, and the interest that seems to be growing every day, about these bikes on this site, I thought Harry better have a page for his bikes, has I now keep finding out more and more about the guy.

 

 

This is the frame kit that Harry started the Foster "Otter" breed with.

 

 

This is Rick's well worn Foster "Otter" that he bought in Oxfordshire ,with probably a GB B40 engine supplied by "Johnson's  Cables" from Banbury,

They seemed to supply most of the engines for the "Otter" projects at the time.

It was during the period of the Foster "Otters" that the WD were selling of the surplus spares for the BSA B40's. The last of the British built bikes supplied to them.

 

We would love to hear from anyone still owning a Harry Foster built "Otter" in any condition.

 

Here Is another that Lives in Belgium, and was ridden in the 2016 TALMAG trial by

J Castiaux.

I am personally looking for a frame to rebuild for my youngest grandson Edward for his first birthday.

If you remember his brother owns the John Draper BSA B40.

 

Although Harry had borrowed BOK228C from Colin Dommett to build the jig from, he  took the decision to make his frame better has you would do, upgrading any design.

 

So for a start the swinging arm box was made wider, for better tyre clearance. and a new swinging arm also fabricated to take advantage of the extra width now available.

 

Later frames had the swinging arm box dropped slightly to give more ground clearance etc.

 

It was Harry's philosophy ,that if he was going to fabricate this new frame kit, he would build into it every bracket and fixing for the engine to be fitted.

So that the new owner of the kit ,would be able to build up his new machine using this kit with in twenty four hours of receiving it if they wished.

 

Well we know it does not work like that? But It Could be done.

 

But the philosophy was right, the frame was designed so this could be achieved! that is how the man worked practical to the last detail.

 

 

When I have sifted through what I have, I will place the stories onto this page.

 

Now If you have a "Foster" Otter, please let me know, about your bike and how you came to own it? We would love to put the story onto Harry's page too.

 

And don't forget I am now looking for a "Foster" frame, if you have one you don't want. Breaking News Shortly.

 

 

Carol and Harry Foster also enjoyed years competing with there superb Triumph trials outfit, before Harry concentrated on doing what he loved best constructing engineering master pieces. This trials outfit was one of the items that quickly gave Harry the tag as being a suburb engineer.

 The frame for the plot started life has a Rickman Petite Metisse scrambles, Harry then attached his integral sidecar to this. Front forks were Bultaco. The engine unit was a really special affair. The Unit engine was fitted with a BT-H magneto running directly from the inlet camshaft; it was that good a job it could have been done by the Triumph factory.

Harry and Carol had numerous victories on this outfit, but the best result was becoming runner up in the 1975 British Experts Trial.

 After years competing on this super outfit, it was eventually sold on to. Anthony and Marcia Beeching.

 This Below is I believe one of the missing "Triumph Otter" Frames , being put to good use at the 2010 Classic Trials Show.

Harry also built over "eighty" trials sidecars for other people including the ones for the Fantic team. 

Here is Will Hawkes and Howard Crafter with a "Works" Fantic fitted with a Harry Foster "Otter Products" sidecar.

Will replied to me on Trials Central,

Charlie don't forget that Harry made many a fine sidecar as well as the solos.

I can remember stopping at his house for tea in the days when we rode the West of England trial on the Saturday,and the Otter Vale on the Sunday,when Harry would come out and ride one of his outfits and beat most of us ,great days ,, Will

 

 

So I replied to Will.

Hi Guy's.

 

 Hi Will,

 

Harry Foster , was one of those guy's that left this planet to early.

 

He would not describe himself as anything, but was meticulous at any thing he did.

 

I am only glad that I have been able to bring a bit of recognition to the work he carried out putting his interpretation  into the forward thinking and simple design for a trials frame  to achieve a

 

winning formula, started by Scott Ellis and his father, then aptly improved and adapted by Harry Foster,  and also given a name that has stood the test of time , that is the "Otter".

 

The frame and Harry Foster  in my mind are "Legends".

 

Regards Charlie.

Here below are some New pictures sent by Ian Ballard of his "Foster Otter" Triumph frame.

 

 

This is a New Foster "Otter"frame that Ian Ballard bought from Harry many years ago.

 and has pledged to finish building the bike we will follow the build.

 

 

We could only hope for detail about the Foster Otter frame like this to emerge a few years ago.

 

 

This shows that Faber made a good job of copying Harry's frame!

I do like the swagging of the seat tube to give more chain clearance.

One thing not copied by Faber.

I must say that people that have ridden both the Foster Otter's and the Faber,

Have always said that the Foster bikes always handle a lot better?

I don t know until I try a Harry Foster Otter.

 

 

 

Good luck with the build Ian, and if you need any help we are here.

And thank you as always for backing me from day one with this website and helping make it what it has become today.OK.

This is Dick Ramplee competing in France, on his BSA engined Foster Otter.

The last frame to come out of the Foster frame jig?

The frame Harry built to take a Triumph motor, But Dick decided to fit a BSA unit Probably with some input from George Greenland?

One last action photo Of Dick riding the bike again in France, for now, but I hope to get the story behind the build of this machine later.

 

 

More updates Later. And don't forget Breaking News Shortly. OK.
