General Trials Talk

I have a 2009 Gas Gas Raga Replica 300 and it has this Sachs rear shock that is "non-rebuildable." I would like to replace it, but Trials bike parts are not always so easy to find in the USA. Trying to find a replacement shock has frightened me, as I want to buy a new one, but they are expensive and I do not want to buy the wrong new one. Am I over thinking this? Can I buy any shock for a Trials bike and slap it on the ole' Raga? Or do I have to ensure I find one with the exact length eye to eye, and exact diameter of "eyes" at each end specific to the 2009 Raga, and if that is the case where can i find that?

Hi Guys I've just bought a tiger cub in need of restoration and would be grateful for any info on the best places to get spares and trials parts . I live in Bristol so any outlets in the South West will be handy to know. Thanks Rob

Hi I am looking for help/information about my 1980 Fantic 200 rear kick please. I am in the process of sorting out my Fantic 200 and the distance between the shock mounting points is 203mm from inside frame mounting point to inside mounting point at the top on the frame and 220mm for the same points on the swinging arm this does'nt seem right to me and nothing seems to be bent, even with the wheel in and done up the bottom distance is still 215mm so the rear shocks are not parallel. I wonder if someone has replaced the swinging arm with one from a different Fantic. Any views or help would be appreciated. Thank you.

I'm starting a new thread so we don't annoy the experts with our chatter and foolery...

I realize this may be a crazy question but has anyone used carbon fiber as a silencer packing? It’s sound insulation properties are very high and it won’t burn or get brittle. I know it’s expensive but it might just last indefinitely in a muffler and could possibly be reused once it’s fouled. Seems to me that sound decibels would decrease and would last a good long time. When it comes to acoustic properties, carbon fiber is often compared to materials like aluminum, steel, and fiberglass. Carbon fiber generally has better acoustic performance than these materials, as it has a higher stiffness to weight ratio and lower density. Laugh if you will but I’m just wonde…

I have always owned GasGas 2 stoke trials bikes and am now considering a Beta Evo 4 stroke. Are the 4 strokes a pain in the rear for maintaince? The gasser 2 strokes rarely gave me trouble. Does anyone know if the betas valves or timing need a lot of maintaince or are they usually reliable without a lot of fuss. Any input would be appreciated. Thanks

The front caliper on my '21 TRS has an annoying tendency to drag constantly and I can't seem to fix it. Couple of days ago on a long steep descent it overheated so badly I completely lost front brake. It wasn't from over use of the brake, it's a hill I've been riding a couple of times a week for quite a few years on a variety of bikes. I am very careful how I use the brakes and it's not a problem. But this time the brake was dragging really quite hard - it would start to skid a little on flat, loose dirt with no brake applied. I took it very carefully down trying not to use front brake at all, but it still completely overheated to the point of the disc just beginning to…

Hi all I am looking for a bike for my 10 year old lad. This will be his first bike. People have suggested a ty80 as a good starter but I can’t help think these are a bit outdated now? Having said that I don’t want to spend a fortune if doesn’t carry it on. The ty are in budget along with the 50cc autos from beta etc. Would the 50cc autos be to small for him are they any good or should I go down the clutch/geared route ie ty80 ……….any help or advice much appreciated

I've just done a top end decoke on a friend's (low hours) 2022 TRS 300 and was astounded at how tenacious, dry and thick the carbon deposits were that completely covered both the piston crown and the inside of the head. It ranged from 0.25 to 0.5mm thick. The tenacity and hardness of the carbon in this TRS reminded me of the carbon that formed in my 1970s air-cooled two stroke enduro bikes running on 20:1 castor oil premix. Sure enough, when I then asked the owner what premix oil they use, they told me it is castor oil based. I'm accustomed to seeing soft, wet smudges of carbon that cover about 40 % of the piston crown on my 2 stroke trials bike pistons. Is…

Hello everyone, i would like to knof if the clutch cover of a montesa 4rt 260 is the same as te one from a 301? Greathings, Luc

Hey guys, Ive always wanted to give trials a try but with my location the bikes very rarely pop up(in Mississippi and grew up in Louisiana). That said I competed in the Redbull TKO on an electric bike(surron light bee) and finished the race. I sold that bike and planned on getting another more capable electric bike but it sold before I could get it so it got me thinking since I have the money looking into a nice trials bike to really hone in my hard enduro skills. Ive been doing some practice based on IRC tire guy on YT on my beta xtrainer as that is my main bike with the electric sold and want to try TKO again either on bigger electric(Electric motion or Ultra bee) or th…

good afternoon i need to change my 4rt ( actually a 4ride) shock linkage bearings; does anyone have any tips ? tia john

Bought this trials bike for my 6 year old. After some time we ve finally got it working but the fan that came on the bike looks like it's been a make shift fan and is completely knackered and fell to pieces.. can anyone help me with this, such as will any size bike fan fit, does it have to be from another txt boy 50 bike?? Or does anyone have one that can be purchased??

Is it possible to get just new blank plastics for my 2019 Beta Evo 300? I have the white plastic with the blue and orange/red color scheme and would like to go for a darker red/black one. Let me know if anyone has any leads on where I would go to for this!

Can anyone offer me some advice please on my Xblok front brake calliper, fitted to a 2011 Beta Evo 290. Cant find any info on Xblok online, is it an old / discontinued brand? 2 things, 1, where can i get a piston / seal kit? 2, whats the tool called or type of tool used to remove the gold calliper covers ( looks like a larger version of whats used on Hope MTB brakes. Thanks you

If you did not know yet Busto has signed to ride for VERTIGO.

Brand new to trials. I have a 04 Scorpa 125 which has a stop button. Just wondering if there is much difference between the Apico & more expensive Leonelli ones used on modern Scorpas before I buy one?

If you do not know yet then Raga has signed to ride a SHERCO.

Hi just wondering if anyone can help I have a beta 125 2004 trials I went out today and revs stuck on full and I pulled kill switch no joy still didn’t cut out so had to put ht cap off checked carb and throttle in fine not stuck not nicks in cable slider hits bottom carb fine soon as I start it just revs up full any ideas thanks

This is very much just a personal observation, but I'd be interested to hear how it resonates with others. The last "regular" trial I went to was a bit of an exercise in frustration - I was (knowingly) riding a grade at & above my abilities because I enjoy a challenge and I don't care about placings. I ride for self-satisfaction. That 2-day event saw me really struggle in parts, taking voluntary 5's on a couple of sections. The second day I dropped down a grade which at least let me ride every section. Last weekend I went to my first Gate Trial. Lot's of fun - more fun than I think I've ever had at a comp. Last lap I decided to go for maximum points (1…
