Thanks lemur ill search jitsie

Add the word Jitsie to your search 👍

Hi everyone. I'm totally new to trials, and to fourms! . I just bought a 2007 rev 250 4-stroke. All I could afford at the moment. I'm just wondering where would be the best place to source parts? I can't seem to find anything on line. Every search seems to throw up parts for the 2504t RR )which I assume is a beta enduro bike)? Or the 2stroke trials, but not the 4stroke. I want to service it and do fork seals and replace a few bits etc. Thanks in advance Noel.

These boots are known to have a problem with the rubber inner top toe protector coming away from the boot when in use as it is not stitched just bonded , do not waste your time taking them back to the dealer if this happens just stick it back on with flexi type superglue gel.

It is the same as a 2010 model . It was fitted with cheapo tyres Pirelli MT43 that are not proper competition tyres, I think the rear shock was a OLLE the forks should be Marzocchi steel stanchioned forks as most 125cc pros had until the TECH forks appeared when Marzocchi went bust. go to www.thehellteam.com and search under Tech support GasGas info.

So i found this bike for a good price I'm picking it up in a few days. It's going to be a spare bike so when buddies come to the house they have something to fool around on. It was listed as a 2013 and my first thought was the seller was just incorrect on the year. The more I research i think it actually is a 2013 (10th character of VIN is N). I think its some kind of economy version that used old left over frames and cheaper suspension and brakes. If that's true I don't know anything about this version. Can anyone fill me in on details? Specifically the suspension and brakes?

New boot day😁 forma boulder comp,size 45 first impressions are they are a lovely boot nice fit should break in nicely i bought these as I can’t feel a thing with my x-power mx boots,obviously not as protective but as far as trials boots go they seem really sturdy.

I know what engine I would want to hold wide open until it runs out of fuel and not expect it to burn up, it's going to be the Honda.

Here's my analysis of that dyno comparison: https://www.electricmotiontech.com/home/what-makes-a-good-trials-motor/zero-loss-gearbox-anlaysis

Now consider the rpm the engine can pull:

Beta has a 6-speed box. I'll let you do the calculations.

Montesa 4-stroke is So much broader in the power band compared to any of the 2 smokes, there would be no keeping with it in the long run. 4T only fire on every other stroke and don't burn oil the entire time.

Ok, thanks for the responses. Given that there only a limited number of long range/seat & tank kits available the options really are only Sherco, Beta, TRS.

that bank sensor is already gone on my bike you do need modification to the wire loom for that This is alex ferrer's bike anyone knows where they put the ignition coil? I think this looks a lot neater that the stock bike who is full with tubes and wires everywhere and a pain to work on.

Thanks for replying,👍🏻 I have mx and enduro gear I just wanted another option for practice and my local green lanes. ive just bought some trials boots as I can’t feel a thing in my mx boots haha and fancied some matching trials pants. i only potter around so mx kit always feels so over the top,although I do like to have some protection. Probably go with the Hebo pants with d30 shorts I think.

What’s the best gearing for the 93 Climber? I have 10 front and 42 rear.

Anyone have a parts manual to the 92,93,94 Climbers? I have the 89 manual but there is some differences. Thanks

I couldn’t find any when I last looked. Most trials pants don’t even have pockets. I got some MX pants instead and have been very happy with them. They don’t have built in pads but do allow room for knee and shin pads. They also have leather patches at the knees to prevent burns from the exhaust. As far as hip pads go, you’d likely have to buy shorts with padding sewn in and wear them under your pants. They make them for mountain bikers and other active sports. There are both summer lightweight MX pants and fall/spring pants. There’s a much wider selection of MX pants out there than there are trial specific ones. Bonne chance! P.S. - If you do buy padded shorts or separate pads I’d recommend D30 type non-Newtonian liquid pads and not just foam. https://www.d3o.com/partners/solutions/ https://g-form.com/collections/baseball/products/elite-sliding-shorts

Hi everyone😁 are there any trials pants which have knee and hip armour or pockets to add your own? ithe hebo tech 2025 look good with there level 11 knee armour but no hip armour as far as know. basically im looking at a very lightweight summer pants to do my local green lanes and trials practicing. cheers in advance👍👍

I think you want something with a 6-speed. Here are overall ratios for two "obsolete" bikes. OSSA TRi 36.93, 29.99, 24.78, 20.73, 14.2, 8.45 Aprilia Climber 37.81, 29.65, 21.5, 15.45, 12.18, 8.45 Plus, one current bike (but it uses GG's 4/6 system and shifting will be more clunky than a true 6-speed). GagGas Pro (all) 31.77, 27.27, 23.19, 19.91, 11.93, 8.7 Here's the Montesa 4RT for reference 36.36, 30.97, 25.97, 16.53, 10.58

TRS are first three close together & big gaps from 3-4 & 4-5. So big I had to put a 56 on the rear of my 125RR so I could actually use those gears on more open higher speed single & double track.

Thanks for the responses. Just to be clear, I don't expect to ride a trials bike like an enduro bike, I'm just looking for advice on the spread of gear ratios. Apart from the 321 TXT, can anybody advise which bikes maybe have 4 section gears rather than three? I believe perhaps the TRS?

With the Jitsie electric start kit, the bank angle sensor assembly is removed. I'm not sure that is a good idea but assume it was done to make space for other components. I have seen no formal description of what the sensor assembly does but it likely cuts power to the fuel pump when the bike is on its side. I guess is could cut power to the whole FI system.

Thanks however I am more interested in originality
