Classic Trials

How many people out there are restoring old trials bikes at the moment ??????????? theres gotta be loads of us?? We must be mad???????

Hi Guy's. I am fuming. Another blow to the Super Cub Trials Projects. Behind the scenes some of us in this country UK. Have come up with the idea to build a cheaper to produce home build Classic styled trials Machine. But there seems to be total dislike in what we set out to achieve by the whole of the trials organising committees across the land, and even the motorcycling authorities. Why? Is there a commercial interest somewhere that I don’t know about? That is backing a campaign against what we were setting out to do? Look the exercise was simple; buy a little motor unit for around the £300 mark, and put a rolling chassis around it for has little as possible. M…

Anyone think it would be a good idea to introduce rules to prevent twinshock going the same way as P65, or failing that to introduce a specials class where it would be quite ok to ride converted monoshocks, or expensive custom made hybrids built using parts from later bikes?

The Edinburgh St George Motor Club are in the process of fixing dates for 6 Sunday trials and some Saturday afternoon trials.These trials will be for twinshock and pre-65 bikes only competing on two routes and will be run in central Scotland.We currently have permission from four land owners and are hopeful on the others.We feel the classic scene in Scotland deserves trials dedicated to the older bike.Once dates are set we will let you know through the usual means,Get those old TY's, bulto's, fantics and good old British irons out of the shed and come along for a good day's fun,thanks.Tam Dodds

I know there has allways been a big debate about pre65 bikes, specially when you come to speak about the Scottish pre65. I would really like to LEAVE APART THE SCOTTISH PRE65 and speak just about the 21´st Century evolution of pre65 bikes, and were and when should this evolution stop (if it needs to be stopped...). We can see what both technical and sportive rules are doing to the modern trials; will this happen with classic, specially pre categories?? To start the debate let me show the next example; this last weekend I went to Telford show, where you could see lots of pre65 bikes. ¿pre65 some of them? ¿really? Just have a look to this two: Ok yes, maybe both of the…

I've always hated the term Pre65 and welcome the idea of "British Twinshocks" so if you do too what eligability critera would you have? I'll start you off with my ideas. Engine : Obviously must be based on crankcases, barrels and heads as produced by the British Motor Cycle Industry prior to 1970. Copies allowed but must comform at least in exterior appearience to the original item. Internals: free. Ignition system: free. Carburettor: free but no fuel injection. Clutch must be cable operated. Gearbox free. Frame : Must obviously be twin shock and made from steel. Shock position free but shocks minimum 340mm max 360mm. Wheelbase without rider to be minimum 50". Ground c…

These are some rules for Pre65 which came out part way through this discussion after adjusting for comments so far received (will continue to adjust if more comments come in), put here so that they are easy to find. The actual start of the debate comment is below. = Pre 65 Rules = 11/9/2021 v1 The following rules are designed to enable organisers to cater for the two predominant types of motorcycle currently being entered into competitive modern Pre-65 trials events; that being original bikes and modified bikes, with the minimum of organisational overhead. Existing riders of modified bikes will see no difference in their entry. Riders of or…

Please could those interested in this series read the proposals outlined in the attachment below and provide feedback via this forum. Please note - I can give no explanation to any issues that may arise as I am posting this on behalf of others and the object of this exercise is to try and gather as much useful information as possible .

Hi, can anyone help me with any information or photographs of Wasp RT4 with Villiers engine circa 1964. I am in the process of rebuilding a RT4 and this information would be most useful to achieve the correct period look.

Hey, i'm looking to bild an ariel 500 that i could use for modern (clubman level) and oldtimer competition, where can you get the right frame? long stroke or short stroke? wat engine mods? i would like something like G. Dufou's bike, M. Grants bike is a bit to much of it regards bob ps i now that it is cheeting but i intend to use it in twinshock events where i use an tlr 250 now would it be easier to use a B40 donor bike ? any idea of prices for the frame?

The way the acu rules are for the classic championship in my opinion could do with revising. At the moment there are 5 classes. Pre 65

There now seem to be several new updated chassis kits available for P65 and twinshock bikes, wonder if anyone knows exactly what is available and the prices being asked?

Just got my entry back to ride in the pre65 scottish, look forward to it, so if you see some one lying on the deck under a 1947 500t norton it will be me

Just been reading an excellent article on the Mid Atlantic Vintage Trials club web site concerning an AJS project using one of Sammy's fibreglass fuel tanks. The addition of 10% ethanol into petrol in Maryland USA has caused his tank to dissolve, leak and clog the fuel line and carb. Anyone else had this problem? Apparently some fuels here in the UK (Tesco for one) have had 5% ethanol for some time. Several other projects of interest on the web site too.

Hi, I have just acquired a 125cc Puch Dalesman Trials bike in need of more than a little TLC. It's been years since I was involved with trials and I've lost touch with where to get parts etc. Obviously an old bike like this presents even more of a challenge, but if anyone has any information, pictures, manuals etc that I could purchase, copy, borrow I would be really grateful. Also if there are business that specialize in this bike or similar I'd be happy to hear about them. Thanks! Ian

Now that the Regulations are available for the 2013 Pre 65 dont you think it would be well just for the organisers to refuse any entries for next years trial from riders who were excluded from this years event . In my opinion it would only seem merited , if nothing else to discourage riders from blatantly abusing the Eligibility Ruling as the 5 competitors did at this years event. Cubette

Guys .looking to start twinshock trials .. What is the best bike preferably Spanish Based in the South East with decent budget thanks

G'Day We have an ongoing discussion going on in Australia regarding the fact that a Bultaco Sherpa M10 won our national championship Classic (Pre 65) class last year and with the championships coming up again soon we need to know the facts about this model of Bultaco. Can anyone tell us without any shadow of doubt that the M10 was available to the retail market prior to Jan 1st 1965. My memory isn't clear enough to recall when Sam first appeared on his Sherpa but somewhere there must be facts and figures to either support or dispute the legitemacy of the model over here. I need to be refered to manufacturers records or something definite that proves when mass producti…

Hola, So, is Robregordo the bonus prize for missing out on the Pre 65 Scottish, hands up who's off to help empty the Spanish wine lake..... and take in the trial as well. Anybody fancy breaking up the journey down, I live about three inches down from Limoges and three inches in from Bordeaux have access to some excellent if not superb trials land, so if you want to get you eye in before the trial let me know , its about halfway in distance. Hopefully Micky and I will be there on twinshocks so the countdown begins.. Hasta la vista....
