Scott Ellis's BSA C15 Works trials bike,

BOK228C,with the frame that Scott built.

Scott  Built this BSA C15, that we all copied, and this type of frame is now, known as 


   "The Famous BSA "Otter"...

OK... take a good look at the frame in this photo, this is the last incarnation of the Scott Ellis framed BSA C15, the nickel plated one, that  Colin Dommett eventually bought and still owns.

Now I am going to throw a spanner into the works...

Because having studied all the photos and material that I now have, I have come to the conclusion that the "Black" painted frame version, the one Scott won the 1965 British Experts Trial on... Is a different frame to the plated later version!



(Do you like his trade-mark flat hat...)

This was his father Sep's and used to mop up the oil on his work bench  in the Ariel - BSA competition department.



This Image of Scott was taken from one of the brilliant Offroad Review magazines.

The start of the Ashfield section just south of Rhayader in Wales. Scott riding in the 1966 British Experts Trial....


Below, is a close-up of the 1965 British Experts Winning Black frame and again used in 1966.

And I think the steering head reinforcing plates are different, than I feel the later chrome plated frame had?

Note: The well dented front rim, When Scott won the trial the year before, he still had steel rims fitted to the bike... The frame was later nickel plate...Or chrome...  Or was it, or was it the new frame, and like nearly all of the BSA works bikes at this time, scramblers and trials bikes they were plated....

I have messed with this photo I scanned until I got the best filter, to show that the gusset welding along the top tube is in a different position on the middle of the tube, where it should be, and not underneath like on the Plated frame.

This is the only picture reference I had at the time I built my replica frame. (2005)...

And the Plated frame has been gnawing away in my head for years.

And it is not until now that I tried to get a better filter on one of the photos Deryk Wylde sent me, that I came to the conclusion the plated frame is different...

If I was doing the exercise I would not strip a painted frame to get it plated.

(I know Pat Did).

But that black frame had done two long seasons and It would make sense to just build another frame.

Don't forget the BSA trials team was disbanded at the end of 1965. although the riders had some good results in 1966.

Scott could do what he liked with the machine he had now purchased from BSA.

The story continues...


When I first thought about doing a Scott Ellis replica, I placed a forum thread start on Trials Central This was 2006 Title "BOK 228C is Lost". well then in January 2007 I had a personal Mail from Mike Pearce down in Andover way.

He said that Mike Whitlock and him had been given the Scott Ellis frame to assess it to see if it was worth their while copying it.

Looking at the frame, Mike said he thought it was poorly built, and very amateurish, and by now way out of line, and he thought the tubing used was from an Ariel frame.

Don't forget I was Green on the subject then, and thought, Ha well, if that was the frame I would just do my own interpretation, and then the forum subject changed as they do, to alloy hubs, and other things, so basically I put what Mike Pearce said to the back of my mind.

And it is not until now years later, that the relevance of what he said then, makes sense now...

Well we have several versions of the way Ally Clift had stripped BOK228C down, and then asked Harry Foster if he would make a copy of the Scott Ellis BSA frame.

But this frame, "Did Not", go out of Ally's keeping to anyone else.

So the frame that someone had given Mike Pearce to assess must have been the first "Black" frame, that they had got their hands on from somewhere...

Now we think it may have come from Tig Perry in Gloucester, when he built Scott, the second frame?.......Only Scott can put us right...


So Now we have the photos blown up to see the difference in the two frames this all makes sense, perhaps Scott may even prove me right? 


This is what Scott Ellis said in the Classic  Motorcycle, May 2010.


After testing Brian Martin's own bike, "BSA 250", Scott decided to join BSA in January 1965.

For the first six weeks or so of 1965 Scott rode Brian's bike, but then was given his own, BSA C15 BOK228C...

 But compared to Brian's bike this bike felt heavy, wide, and gutless.

Being in the "A" team along with the Lampkin's , Scott had to do his best with what he had.

By the time of the Scottish, he was just about getting to grips with the bike, and was having a good ride, until the big end went bang...

Here is Scott riding that first works C15T on White Rocks in the 1965 John Douglas Trial.

Note: The "Works" modifications to the frame, Brian Martin and Scott took a Large hammer and piece of timber to the front fork down tube? To give more front wheel clearance as in this shot, for the 21" front wheel fitted, with full suspension movement...

You can see why Scott decided to go it alone and build his own frame for the BSA, the two seat tubes had also been pulled in to make the waist area slimmer.


 The C15 trialled by Brian Martin was very different to a standard machine, so with his boss's approval, Scott decided to make some radical changes to BOK 228C...

In addition to his trialling and scrambling Scott had tried his hand at grass-tracking, on a B40 engined "Elstar."

So influenced by that frame, and the one from the Ariel HT, Scott and his father designed and made a frame for his trials bike.

 With Brian Martin's blessing and support the frame was completed by early November 1965, and first time out riding in a Midland Centre Group Trial he won the event...

The higher management at BSA had no idea about the frame,  or what the Comp shop were doing.

So when two weeks later after Scott had won the British Expert's trial, the press where clambering for information about the New Bike?

Brian had a lot of explaining to do, but passed it off has just an experimental machine...

This satisfied the top men at BSA, who had already used Scott's win in the British Experts to plaster the motorcycle weekly journals with full page adverts saying how good the BSA was.

  But Scott found it most frustrating when BSA could have so easily built replicas of BOK228C. Without that much expence... 

Anyway, Scott continued to ride the bike in all the major championships and just kept the heavy bike for  trials like the "Scott", where it was tough going for a lightweight machine.


Scott eventual bought all of his bikes from BSA in 1967 and continued to ride BOK228C up until 1969.


Here's another shot of Scott riding  BOK 228C now with the fully  plated  frame and forks, has it was in its last guise,

 This is the famous Hawks Nest section.

Scott's own story here! later,

fingers crossed.BOK228C...



This is Scott's last BSA trials bike, but now owned by Colin Dommett.

Here is Scott riding his BSA Antig Grass-Track bike. this was 1966-7 when Scott was using the money he earned Grass track racing to buy bricks and morter for the house he was building...

BSA were still supplying the parts for the bikes, and Scott got through a fair few parts, with some spectacular blow ups, with the grass engines.


Right remember the name "ANTIG". then look at the next shot.

This is Tig Perry of "ANTIG" Fame, superb grass-track rider and frame builder.

ANTIG Engineering started in 1966.

Tig went on to buy the HAGON frame business too.

So what's this got to do with Scott Ellis and his trials bike?

Well has I stated above, I think that Scott had two frames on his last BSA trials bike.

Now look at the gusseting around the Grass bike Tig is riding, and then look above at the Derek Hopkins photo of Scott's trials bike.

"Snap" they look the same.



Tig and Selwyn Perry both lived in Norton  Gloucester....Tig started building the "ANTIG" frames here , leaving his elder brother Selwyn to build his frames  near  Newent on the Ross-On-Wye road. These were the "ANSEL" Grass bikes.




Tig and Selwyn both lived in Norton, Gloucester, and worked in Gloucester, the first bikes were built on the farm between them, while Tig was working at the CoTTon factory, they later worked,...... Tiggy (Antig) (Gloucester,) ( St james street.)


and Selwyn .......(Ansel), Cheapside, Newent, Gloucester) .


Sadly Selwyn was killed in a road accident near his home in Gorsley,near  Newent on the ......

Here Selwyn Perry forces on in his own personalised style, on a BSA engined


Look at the motor, and the cases look very much like  the "Cotswold" motors put together by Roger Taylor,  (RTS), and John Husband .



Well you remember the first time out for the Scott version of the BSA Trials bike.

And this would be Number one... He met Colin Dommett to go practicing and then back to the CoTTon factory to repair the footrests.

Then Scott ended up with a "ANTIG" grass bike from the same city. This was only probably because of the sudden passing of Alf Ellis after his fatal car crash, well you can read the ELSTAR page for that.

So I am going to stick my neck out, and say that the Chrome-Nickel Plated frame, the one that eventually got back to Colin Dommett was built by ANTIG Engineering Gloucester.

Unless any one says any different?.......Scott...

Good story anyway.

This is my replica  in build of BOK228C.




OK... I know this is a really bad picture taken with my I phone , and I will replace it as soon as possible.

But it shows now how close to the Scott bike I got with only a photo from the Don Morley book, Classic British Trials Bikes.  so I am really pleased. Even more now, I have realised that the Plated frame must have been later manufacture...



Now I am  finally getting the engine together in the Specification  I have always wanted.

I thought it would be sensible to create a page for my Scott Ellis replica of BOK 228C. And not leave it on Scott's. page. This then leaves more room for pictures and wording for the original,

Ex works BOK 228C.


Just one more picture to show how much tyre clearance there is with a Sports Cub swinging arm? And this one on my frame has been lengthened by 1"inch. By me.

But a Triumph TR20 Cub the bike Scott had been riding before the BSA contract must have been in his head while riding the heavy C15T... So he set out to to emulate the "Works Cub" that he had been riding before the BSA, which was a lot slimmer and lighter bike to ride....So you could see his thinking...Build a Triumph Cub with a BSA engine...




More from Scott Later.We Hope...
