b40rt Posted January 28, 2013 Report Share Posted January 28, 2013 Alan Whitton makes (has made) replica cub hubs. Quote Link to comment Share on other sites More sharing options...
totalshell Posted January 28, 2013 Report Share Posted January 28, 2013 your aprilia forks arent modiefied to make them look pre65.. .. the sliders would be turned down so that they are wafer thin then a pair of norton sliders are bored to accept the sliders and the two are married together.. this is not a cheap or quick operation and if you have to ask the price then its too much. just look how much the norton sliders are fetching.. if any become available Quote Link to comment Share on other sites More sharing options...
old trials fanatic Posted January 28, 2013 Report Share Posted January 28, 2013 A pair of hubs and the forks modified assuming you supply the forks and the Norton sliders wont leave you any change from £800 then you need the wheels building up spindles making and of course fork yokes and dont forget the frame mods and at least electronic ignition. Now you see why a decent Pre65 Cub will set you back £5000 and thats for a used example. Quote Link to comment Share on other sites More sharing options...
tony283 Posted January 28, 2013 Report Share Posted January 28, 2013 Depends what specification you are building to and what events you intend riding the machine in. The "cheat" forks are expensive and why they should be acceptable to the Scottish Pre 65 is still in my mind unreal as nobody, but nobody had them fitted back then ! ...... and again if "that" is THE event youy are building for then look at the frame as well and the fact that it must run on an Amal. If you are building to any other Vintage Trials org, check their regs and you may find you can use B50 4stud forks which has a 3/4" stem and will take a Yamaha TY front wheel.

Tony Just advise me how much would a B50 front end cost in good condition like yours? Your points are valid but most clubs would not like a TY front wheel or rear for that matter.

Then a new piece is welded on and machined to take the spindle so that the spindle is then located directly under the fork. More machining I guess to the sliders to remove evidence of caliper anchor points etc, paint them black and they're done. Quote Link to comment Share on other sites More sharing options...
tony283 Posted January 29, 2013 Report Share Posted January 29, 2013 OTF, that set cost $75 off ebay complete with yokes and stem. Of course in the USA we can use anything up to 1974 for Ahrma and ITSA. No restraints on frame, or carbs with our ITSA trials. Tony Quote Link to comment Share on other sites More sharing options...
charlie prescott Posted January 29, 2013 Report Share Posted January 29, 2013 Hi Guys, I have been pushing the four stud forks for some while now, These forks can be built out of mainly new parts quite cheaply compared with any thing else, mainly using Wassel parts. Wayne Weedon makes vented caps for these forks now and we are working on other parts for the forks. TY 250 fork yokes can also be used.and don't forget these forks were 1966 in origin? BSA GP Victor! And are a lot more British, than most forks used in the so called Pre 65 . Regards Charlie. Quote Link to comment Share on other sites More sharing options...
andy m Posted January 29, 2013 Report Share Posted January 29, 2013 I believe someone has had "new" Roadholder bottoms cast. Had a price from Alan Whitton to machine Marzocchis to fit 3ta/5ta bottoms, I need to find some first but it wasn't too bad a price. As others have said depends on what you intend to ride, as I am riding BMCA events which have a specials class it's easier to build a bike with what is to hand without taking the p*** and tick the specials box on the entry form. If however I was to take the plunge and try for Scotland I'd need to change the forks and fit an Amal carb, Who knows one day maybe? in the meantime I'll ride the bike I have built. Next build is a C15, it will have Fantic forks and wheels, I'll just tick that box again......... Quote Link to comment Share on other sites More sharing options...

The carriage alone would cost more than that over here. Id be amazed if you could get them in the UK for under £300 and all that for a set of forks that would be "illegal" at a lot of clubs.Obviously much easier and cheaper in the US with their rules.

carl ekblom Posted January 29, 2013 Report Share Posted January 29, 2013 I guess that Royal Enfield fork legs would be legal. Its a fifties design. They are 35mm and they are cheap. I will use them on my pre 65 bike. http://www.ebay.co.u...=item27cf241276 or http://www.hitchcocksmotorcycles.com Quote Link to comment Share on other sites More sharing options...

Leading axle methinks. Think you will find it's been tightened up since i think it was Calvert won with leading axle forks on a cub. Quote Link to comment Share on other sites More sharing options...

The SSDT pre 65 rules say nothing about leading axle http://www.ssdt.org/... Entry Pack.pdf As far as i know the design is externally identical or almost identical to this 1955 design http://www.hitchcock...ssembly_-_contd. and I have seen it on photos of trials bikes in the late fifties.
