A Guide to "Pre 65 Rules" as I see them,


And Now what should be

A"Classic Trials" format.

Or even "Britshock" class of Machine.




                   This machine should not be classed has a Pre65 trials machine.


                               This is a "Brit-shock" bike? very loosely.


But this guy, uses this machine in the so -called Modern day trials, and I am told does very well.

Now take a look at the Third bike down.


This is also classed has a Pre 65 machine, Is it?


Just compare it with the 1963 bike below to make up your mind if this is so?




This Triumph TR20 Cub is a 1963 bike and correct in every way.


How many Triumph Cubs do you see like this today competing and still calling the machine "the so called Pre 65"
















This is a brand New 2015 built Triumph Cub? but in some quarters classed as Pre 65,Is that right?


OK. How I see what makes a machine Pre 65,and I am being lenient with some of my rules to just use common sense on some counts.


Now this is my definition of what I think should be the "Rules". and this could be pushing them to far?


A British Trials bike based on a image of a machine built before the end of December 1964.


 Now Image means,


 A machine, using an engine and gearbox available at the time,unit or pre unit, or a derivative of this engine or gearbox (four speed, max).

IE, As per the C15/B40 engine, The basic design, even though up rated  over the years past 1964, was still a development of that basic design.




 Should be one available or under test before 1965, this lets in the Amal Mk1-1,1/2  carb, and also some Italian- Japanese carbs that were fitted to bikes before the threshold.

And to my mind if these Carburettors were used on a motorcycle of any make before 1965 they should be alright to be used.




 Should be a silhouette of one built before 1965 but not necessarily one  in production, a replica of a known frame, (with Proof) should suffice?


We know that most frames are now so-called copies of a frame produced before this 1965 time line, but are they realy?

Most are made of lighter and better quality tubing than was about at the time, just cut open a Triumph Cub or BSA C15 frame and you realise that a modern day frame is nothing like the ones produced before the 1965 deadline.

And most have had the swinging arm lowered,or altered at the pivot, and the under engine frame modified or removed.

Subframes have been reduced in width, and swinging arms lengthened and widened.

 Brake drums, rims, etc should be ones available at the time no matter the nationality of manufacture, or sensible copies of the same?

 But do we really allow all of the billet parts now produced onto  a bike with a name Pre65.

 how many CNC milling machines did you see in the year 1965?


 An effort should be made to make the machine look as "British" as possible. IE, fuel tanks Etc.

Yes we did have replacment fuel tanks for our BSA's, the LYTA ones that the fctory used.

 And yes we had glass-fibre mudguards, but other types of plastic used was new to a motorcycle.


Front Forks.


These should be of Pre 1965 appearance. and fitted with some protection for stanchions.

Internals can be of later manufacture, but must be stated as so on the entry form.

But should we again allow Brand Newl'y designed, and Manufactured forks hiding under a old brand name be fitted to a machine, and still call it Pre65?

 the answer is a definite NO....... 

If the majority of the entry have internally altered forks, BSA/Triumph, Four stud forks will be allowed, along with other makes of fork available before 1972. If however an entry was made up of bikes fitted with genuine Pre 65 forks, the bikes fitted with the later 1971-2 forks would be able to compete, but with a penalty of 3 marks lost. Yokes to my mind can be any that are safe for the job in hand, no mater where the pinch bolts are.


Cycle Parts,


Ball ended levers (16mm) and folding footrests are a must.

(both of these for safety sake.)

Bars should be no wider than 840mm. The throttle must return to its stop, and the cable be free running.

Brake arms-rods,and cables, should be adequate for the job.


If, or should I say when, we run our own club trials,

these rules will apply, to bikes I call Pre65 others up to the seventies with British motors will be known has "Britshocks"


It really is now time to Drop the Pre65 name tag on all forms of Classic offroad Competition.

Because we all know that the rules the have enthused ever since Deryk coined the phrase and he admits that mostly he was referring to the sections used and not the machines.

As every one riding in his first events only could afford the genuine Pre65 machines then as they were cheap because no one wanted an old banger.

How times change hey!






 This or the one below or both?





Disagree then let me know.


Well, I have received  an unbelievable amount of interest in these rules.

And it has now spurned  others with this way of thinking to try and persuade the AC-U or AMCA. to  set up a series for Club-men, with British Twin Shock machines up to 1970,with sections that are enjoyable to ride ,on a machine that has not cost the earth to put together, or is still near original.

We suggest that this  series is named "Brit-Shocks".

Jan 2018.

Well we know that did not happen and the AC-U have dropped the last so called Classic series. that was formally the Sammy Miller series of trials.

 This was said to have been dropped because of the lack of entries received for these events.

A couple of clubs including the Stratford upon Avon MCC. have decided to go there own way and run the old Sam Cooper trial using there own rules.

 I hope people will support this effort.

The BMCA still run there Classic series of trial as you know. and usually have a entry of at least thirty riders. with machines governed by their own set of rules. 

that every part of a competing machine must be of British manufacture.

This is al-right but it still lets in the dreaded billet parts and even the NEW forks.

And I must say that the most prominent machine used now by most of the riders is a bike from the Now Super Brand Drayton.

I feel the series will become a one make Specials trial using this brand of machine. am I wrong then?

The Yorkshire Classic club so I am told seem to be having the same problem with a lack of entries to some of their trials.

Is it these NEW Super breeds of bike that has killed these entries, are the sections now being tightened even more for these money pits of machine.

And do the people that have spent £10,000 on a  brand New bike expect priority over lesser influential put together machines.

 These two makes of lightweight machine have just flourished through being just that lightweight, and Mr BSA and Triumph must be turning in their graves to see what they could have done if they had kept going.

 But make no mistake about it these two brands of New machines as Killed not only the so named Pre 65 movement but also the Classic trials scene of a whole.

And we wont start on the influence of what can be ridden in the Scottish Two day trial will we.

I have mails every day asking me what is allowed in their rules. 

And if I am going to build up a machine, and I need to build it so that I may use it in that trial.

All I say as guidance is that the rules up there change with the wind, and unless you have a foreign passport, and a deep pocket to be able to spend a lot of money on New billet parts and fork and frames.

 Just build a bike you can afford and ride in your local trials clubs that still caters


for a Classic type machine.

Faber Otter Cub not Classed as Pre 65. but a Classic in my eyes.






Here is  some old 1960 trials footage which will give you some idea of the type of sections there were at that time.

I might add that I cant believe the lack of grip in the latter part of the film.

So you see you already have an advantage on us guy's back then, the tyres now-a-days "Grip".

Bring on the "TRAD" trials, but we know the time is past, and this will not happen.



Don't think that it is bad news for Pre 65 in all parts of the world because it is just the opposite which must say something.

 What we are getting wrong? When others are getting right.

 I have been told by several of our experienced Classic trials riders , that they don't bother with trials in this country (UK) any-more, but travel to the continent to do their trials riding, because they are excepted  there, and people just ride what they have, and most machines are not in the super trick bracket of machine.

 Just take a look at these trials photos at a trial from Mons in Belgium in November last year.


 So what are we doing wrong not to have this type of support over here.

It has got to be what I have said above, basically too many "Trick" bikes over here.

And people are refusing to even enter a trial, with these machines treated like Royalty while anything slightly original is frowned upon.




A few bikes that compete in France, Spain, Belgium, etc.






Just a fact that anything is ridden.

 Some superb machines, but Not just the two brands, that we seem to be obsessed with over here, and the machines in my mind that are causing the problem of entries here.

So you see it is not all bad News ,and the world is a smaller place.

But have you ever wondered why we only get continental trials riders over here for Three trials a year, and one of them is off shore............

More Later.
