General Trials Talk

Kudos to TRS for thinking outside the box and designing an electric start that drives the ignition side of the crank. My question is why do we need a separate starter motor at all? Current designs use a high speed starter motor geared down to provide starting torque which is engaged and then disengaged becoming dead weight when not in use. With the lighting coils we have an array of coils in a mass of spinning permanent magnets already. If used for a starter motor and then switched to generate power once the engine is started there is no mechanical interface and none of the animal is wasted as the saying goes. The concept of a motor/generator is old. Real old. Starter/gen…

A couple weeks ago I acquired a 2015 Scorpa 300 and made my first post on here requesting suspension setup advice. I was told to report back on how things went. So before I get started, a little history on how I got to this point. I've ridden dirt bikes since I was 14 years old, motocross, hare scrambles, GNCC's and trail riding. At 55 years old I decided to try trials. I've always been a fan of the trials rider-the masters of balance and throttle control-and after attending the AMA Vintage motorcycle days at Mid-Ohio the last half a dozen years and watching the trials events on Sunday morning, I said to myself: "I could do THAT...". So I found my Scorpa two weeks …

Today while riding down a long and technical trail, I noticed my front brake lever seemed to lose its free play and the lever seemed to stiffen up. I continued descending for another 5 minutes and the front brake began to engage automatically. Within a minute, the front brake was locked firmly on the disk. I couldn't turn the front wheel. The lever could not be pulled back. This continued for about 5 minutes until things cooled down where gradually the pressure on the lever and disc relaxed and I was able to freely spin the wheel. I figured perhaps my finger was slightly riding the brake and causing friction and heat. I consciously finished the remaining descen…

the rebound adjuster on my 014 sherco olle shock is broken iv managed to get it apart and remove the broken part just need a new adjuster any help even a parts shock or a used ohlins thanks

I have an 03 sherco and the exhaust needs to be cut open to repack it. Before I start on this task, what damage could I be doing running it in its present, noisy state? thanks

Hi all , so I picked up my bike this weekend, am very pleased .. I have noticed that the previous owner is running 38 on the back and 9 on the front sprockets ... Im sure that standard for the TRS RR that its 40 and 10 .. I understand a little about gearing, but not 100% sure what is happening with this , I'm guessing that its lowered the top end and increased the low end response ?? is this correct, what would be the reasoning behind it be, what's achieved ?? Any info would be great .. Cheers . .

Any cleaver person out there know if an NGK BPR5E is available in short reach ( ie12mm ) Thanks BPR5HS looks correct ?

Kind of a generic problem I think. the fork sliders are from a 75 DT 250 and the seals are aftermarket from "All Balls Racing". The online instructions say to use a fork seal driver. Or if you don't have one of those, use a piece of PVC pipe split in half and put back together with a hose clamp. It looks like the fork tube is also inserted into the slider at the time that the fork seals are driven home. Well, I did it another way with a male plug with a shoulder at the top just slightly smaller than the seal OD on the top end and just slightly smaller than the inner bushing on the inside of the slider.- Then hammered on the bushing I made which should have driven the se…

As im looking at getting a new bike I thought it would be fun to see what peoples top picks are .. ...

I'm just starting out in this sport and doing alot of reading, It seems to me (correct me if i'm wrong) that alot of people are hung up on having the best bike or the best gear as though it is going to improve performance ? I'd like to bet if you put a Toni Bou or a Dougie Lampkin on an ancient machine in the cheapest gear you can get would still massacre most. Thoughts ?

Hi all... So , I have decide to buy a new bike ( new used bike ) , returning to trials after 20+ years .. I looked into this about a year ago, but life was put on hold due to ill relative, but am now ready .. Years ago, I had a sherco 290 , which was my first and only trials bike , I then used a club bike on a event day last year , and then recently I had a day out on a montesa 4 stroke and a TRS RR .. Last year I nearly bought a ossa as they looked good .. So, as it happens I decided against the ossa after reading they went bust , I have also ruled out Gas Gas ... ,I hadn't really heard much about TRS as they wasn't around when I was ridin…

Hi everyone so Iv been on a beta evo 125 for quite a few years now and I’m looking to move on to a 250. I was thinking a beta 250 because I have been told it has the softest power delivery? But does anyone have any other suggestions? Like what is the the new trs like? Does it trump the beta?

I am determined to change the footpegs of my vertigo. my current footpegs are the S3 Hard Rock Steel. I have driven another bike from a friend with the S3 Hard Rock aluminum and I have felt much more comfortable, because they are bigger. The doubt comes, that when looking for new footrests, I see that there is another model called curve. Any experience with these footrests? the one who has tried both, which is his favorite? My level is medium low, although little by little I start using the rear wheel more to jump.

Hi guys, I’m really new to the trials riding scene and looking for a bike, I’ve had loads of experience in motocross and sports bikes but I’ve always fancied the more technical side of things. I need your opinion? 2T 4T make and engine size?

So I've got an odd clutch problem. The bite point basically moves around, typically in, up to a point. After the clutch is let back out, the engagement point will gradually migrate its way back to where it was originally, as evidenced by the free play in the lever. Another way of saying this: set free play to ~2mm, pull the clutch in a bit, let it out, free play is now 6mm. Leave it alone for ~10 seconds and the free play is now back where it was originally set. I've put a master cylinder rebuild kit in it once already, and the problem seemed to improve, but it's now back to being as bad it was originally. I've got a new master cylinder coming. I don't see evidence t…

I maintain my Sons Repsol 4rt & since moving up to National and road trials we are getting through wheel bearings at a Great rate, have used branded & cheap and had a dealer fit a set when changing a tyre makes no difference I even remove the dust covers and re-grease them. Obviously it is worse on the rear wheel. How long do everyone else's last please.

Anyone have any information on how to get a radiator repaired as I think I have a very small leak in mine or do we replace them !

Hi all iv removed battered rim tape from front wheel and it’s left heavy Amounts of adhesive on the rim, anybody had this and what have you used to remove it easily? Thanks

Jitsie have done a short video with Doug and his four SSDT winning bikes, mud’n all. This got me thinking, what other winning bikes are still out there past or present? What’s the oldest, which bike has the most wins to it’s registration etc? Be it SSDT, nationals, internationals. How many are ridden and how many are in museums/private collections? Before anyone lists their modern bike’s club trial victories for the last 5 years...... don’t!

Some of you guys could help me out a bit if you will. I have decided to convert my trail bike to a trials bike, so I ordered new fenders and am fabricating my own front fork mounting brackets. The bike originally came with a 2.75 x 21 Bridgestone tube type tire on it, but that one is long gone. What I need to know is what is the overall width of some of the2.75 x 21" trials tires out there now.? The tire on my front right now is a 3.00 x 21 knobby, so it is almost touching the inside of the new fender .I think the trials tire will be a bit narrower, but different brands are different sizes even though they all say 2.75" x 21" or what ever. I need the measurem…
