Classic Trials

I have a lot of play in the swingarm bushes on my 349 Cota. Is there a conversion to needle roller bearings available/possible? Does the sleeve in the frame/pivot bolt wear, giving similar symptoms to shot bushes? Cheers

Hello everybody, A Fantic 300 front brake plate has been recently sold on ebay for 375

I need to known the best set up for trials gearing,primary ,secondaty ,gearbox ratios etc,,,it looks like this motor has been played around with so need to known the the best set up for trials and where to get sprockets gears etc. Many thanks in advance Peter

Hi. I'm new to Trials Central & usually ride enduros on my FE 400 Berg but..... I've got a nice little Triumph 3TA which is running a 21" front wheel with a trials tyre. However the last owner did nothing to the forks. This means when I ride over speed humps or go trail riding the front mudguard fouls on the frame down tube. It's hitting hard enough that the mudguard then rubs on the front tyre and has been dented. I know that I could put a spacer inside the forks to increase pre-load, and maybe I can use thicker fork oil, but I don't think this will be enough. So I need help. Is there anywhere to get longer after-market stantions, or is there another Triumph that…

I'm currently building a 3TA for beginners trials, green lanes and LDT's I have fitted a 14t front sprocket and am looking for advice/ suppliers of a larger than standard rear sprocket. (Standard Primary drive ratio fitted) I need the bolt up brake drum too. I'm thinking around 54 to 60 rear teeth, am I on the right track here? Also, do we think I will need to fit rim locks to stop the rear tyre slipping (or is the 350 so 'soft' it won't slip at 4 psi ) ? Cheers

I'm in need of a speedo for my 3ta. Not interested in cheap Indian made copies. What I have is the square type speedo drive with the cable drive at the top looking at the rear hub from the right. . 1961 would have had a tick-tick -tick chrono, originals are terrible price! Any ideas on a little trials type? ratio would be 2:1 Cheers Bill

Hi Guys I will be converting slowly royal enfield bullet road model to trials bike . I know in trials bike world 18 inch rear wheel is almost standard. I am thinking of putting 4.0 x 19 Trials tyre on my Royal enfield bullet. as they are availble from vintagetyres. http://www.vintagetyres.com/item/571/400-19--400x19--ensign-trials-tyre--universal--s-r advantage i see i dont need to change RIM/spokes and tyre price is reasonable as well. currently i dont have plans for any completetion. what are the drawbacks of using 4.0 x 19 tyre . > any problem in riding if using 19 Inch type > do i need to make any changes to swinging arm > any rest…

I don't know if this has already been posted (I couldn't find it on a search) but Mitas are now manufacturing 4.00 x 19 trials tyres. Here they are from £60 each on Ebay http://www.ebay.co.uk/sch/i.html?_odkw=&_osacat=14780&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xmitas+19%22+trials+tyre&_nkw=mitas+19%22+trials+tyre&_sacat=14780

Does any one know if you can still get good 400/19 trials tyres, i had a new dunlop tyre come yesterday and quality is CRAP so it going back, i think i will be better of to rebuild the wheel to 400 /18. cheers Gary

Not sure if this is a repost but this video is great ! I,m sure Big John and other pre 65 riders will love this. http://www.veoh.com/videos/v6308839jd2xSk29

Think this has been posted before, but has anybody noticed the rider at 4.49 looks to be using the clutch. Thought this was illegal or something back then !

Hi all, I`d like an opinion from some of you knowledgeable types. Re the bike in the photo - do any of you think it would make the basis of a good pre 65 trials bike or is it just too far "out"? Any comments are welcome.

My vintage project needs front axle seals. The ones found in it are 24x35x4 mm. Are these the right size for OEM ? Its hard finding anything narrower than 5.

I have been considering getting a Spanish twin shock, from the 70s, to ride Twinshock Trials. Which make is likely to be the most reliable? Usable? Trouble free? Spares availability? Anything else? Any comments and advice welcome and appreciated.

What do you think of this? Came upon a 1971 Sherpa T basket case. Motor is shot (chunk out of case, wont turn over, etc) but the frame& wheels are good. I have several 74 TY 250 motors and was wondering if it would be worth the effort to put a yamaha motor into that chassis (providing that it even fits) ? Or try to make a Magesty copy? Any thought or suggestions? Cheers. Mike

OK folks, I am now looking at a 1978 Bultaco Alpina, model 213. Will this make a good trials bike? Other than changing the tank, seat and sprockets, is there anything else I can do? Thanks, Gordon

Hey folks, Just watched a great winter time DVD of the Leroy Winters Memorial ISDT Reunion Ride. Loads of vintage bikes and an interview with Jim Holerich. Malcolm Smith and John Penton were there as well. The DVD was very reasonable and is available by emailing Jay Duchin <jayduchin@comcast.net> Below is a link to a trailer for the movie.

Does anybody know the RAL yellow number(s?) for an 81 320 Majesty tank and frame.

Dunno who's seen this but if you haven't it's worth a look:
