Beta

Hi I'm wanting to repack my evo 250 silencer do you have to do the large box just after where header goes in or do you just do the straight part up before the plastic end cap

Came across this EVO while searching for a new bike/winter project. It needs lots of attention but it runs great! Initial purchase pics and what has been done so far... The tires have 2014 date codes and are pretty hard, especially this Vee Air filter was filtering/hanging on for dear life and ready to fall apart...got to it just in time She is a 290. The cylinder bore looks fine and a quick peek through the exhaust port revealed no scuffing on the piston so the jug is not coming off

Hello The Beta Evo 200 was much appreciated by older riders, who wanted a softer, less aggressive power delivery. Can anyone enlighten me as to when Beta ruined the Beta Evo 200cc by lightening the flywheel, raising the compression ratio and other "improvements" which have spoilt the soft, mild, tractable nature of the engine, making grip elusive in difficult conditions, even for experienced riders? The 2020 models still had the above "improvements". Do the 2021 and/or 2022 models also suffer? Thanks

Does anyone know the torque value for a Evo 200 factory 2022 flywheel nut thanks

Hi, now I believe that these are held in place at the top with a grommet into the frame. Mine was held by a couple of zip ties I've taken the rad out to find this , see pic. I presume something has snapped off , anyone know.? Also the lower mounts, how are they attached to the rubber mounts??. Anyone got a clear photo showing this please. Thanks for your help, I hope. Also, just to add, why do they insist on using cap head bolts with a consistency of cheese?

Hey all, I thought I'd send a message on the forum which I've been looking at a lot lately as I've bought an old beta techno trial bike as my first bike. It's been a lot of fun but I've had some issues with the bike and the latest has been chewing up spark plugs and now not starting. It seemed to be a fuel issue and as I was investigating I noticed the carb seems to be not only not the original mikuni vm26 but a cheap Chinese keihin copy. I've sourced the original carb for $670 through beta but that is not what I want to spend. Does anyone know of a better alternative? Thanks for your time

im going to see a beta evo 200 (2018 model) for my son and was just wondering if there is anything to look out for on them. i havent owned a beta so a heads up on any common issues would be a great help. cheers

Was riding my first competition in 10 years yesterday and noticed a knocking sound whilst riding between sections in 3rd and forth gear. I've never noticed this noise before and I'm convinced I can't hear it in the sections or when I'm practicing. Certainly isn't there whilst revving Bike stationary. Bike is completely standard. Air screw set as per factory. I've never touched it. I run Castrol power 1 racing at 65 to 1. Could this be pinking ? I think the bike is probably coked up quite a bit as I could see it was smoking like mad when riding distances between sections when it actually had the chance to heat up properly. My usual riding is very slow section type p…

Hi Guys, I had posted this in the Sherco forum earlier this week, but the bike I was looking at fell thru which was a 2017 ST300. New to trials (coming from many years of Enduro) so don't want to spend a heap on a first bike. I'm now looking at a 2019 Beta 250 Factory bike and wanted to hear the good and bad of this bike compared to say a recent model GG250 or 300 which seem to be more available on the used market in my area. Thanks

Hi all, as the title says, I am the proud owner of a 2022 Beta Alp 200. So far I am loving the bike, having been in half a dozen rides and around 350 miles of green laning here in Cornwall, UK. I am however, struggling to find parts and accesories for the bike. Currently I am after a rear rack, but cannot find any stock available online or at the dealer I purchased the bike from. Can anyone help with recommendations at all? Many thanks in advance!

Hi guys New to this trials world.. I have beta 200 last week took it out for a spin started 2nd kick then into 1st and all OK then it died wouldn't start for love nor money. Checked everything couldn't see anything wrong ? No spark so took ignition coil off my sons 200 beta till no spark so changed over cdi yeah all OK ran fine.. try my ign coil and cdi on my sons bike nothing .. so ordered new cdi unit left old cdi in the house till today (Sunday) stuck it on sons bike with his ignition coli...works fine now 🙈🙈 why does it now work ?? Weird

As I’m new to trials riding, I want to fit a lanyard-magnetic kill switch to my ‘08 Beta 270. I also want to keep the manual switch. I presume the kill switch is a normally-open switch, which, when used, simply earths the coil. I followed the two wires from the existing manual switch, and added my magnetic switch wires to the same connections-one into the loom, the other, already fitted with a ring fitting, to the earth point with other earth wires, on the coil mounting. So now, when either switch operates, the earth circuit should be completed. but this arrangement now only works when the magnetic switch is removed-when I put it in place, it kills the engi…

So my new to me '04 Beta Rev 250 currently has an NGK BP5ES plug in it and the Beta specified Champion crosses over to a 1 step colder BP6ES plug. What are you guys using and if you are also one step hotter, why? Joe

Having just been set right on a bike I proposed to buy which was identified by a forum member as being mid-advertised as a 2012 when it was a 2005, can I seek your advice in confirming/not the bike below, which is described as a Beta 250 from 2008, please? I appreciate it isn’t a 4T (presumably the plastics or decals are from another bike) I plan to go to see it Friday, but if it’s a wrong’un, I don’t fancy the two-hour drive… thanks in advance

Hi everyone, I have a 2018 Beta Evo 4T. The bike has been unused for 8/9 months. I ran it today and found that the fan didn’t kick in. I tried to move the fan by hand but it was very stiff. I put some penetrating fluid in to try and release what I thought was a seized bearing. I managed to get it to moving but when the engine was run up to operating temperature the fan didn’t kick in. I checked and cleaned all the connection, all were fine. Can someone advise me, is there a way to check the fan independently or by bypassing the thermostat. I’m pretty sure the fan motor has gone but would like to check before committing to a new one. Thank you.

Hi to all I am new to Trials and even though I have been riding for 40 plus years, road, MX and enduro have never owned a trials bike before. I am going to look at a Beta Rev3 250, So here we go what am I looking for as far as mechanical stuff. It has sat for a while, all the normal stuff I am able to spot but is there anything bike specific that I need to be looking at. This bike is 14 years old so there is bound to be somthing I may stumble on ? any advice will be appreciated. Oh yeah I am am 6 foot and 16 stone will it carry me ? Rich.

Hello, i would like to buy a Beta Evo 4T and would like to know iff riding the 2018 model or later is a bigg difference with the 2017 or earliier models. Al your advice or experience is welcome. Greathings, Luc

So I got a great deal on a factory Evo from a local shop. I'm getting it resprung for my weight (225lbs), fork guards and bar ends. My question for you Beta experts is, does it need anything else? And, are there any design issues with the bike I should be aware of? Lastly, what parts are good to have on hand for the bike (air filters, oil drain plug washer, etc)? Any recommendations welcome!! BTW my background is trail riding 300 KTM's and I'm fine doing maintenance work on the bike myself!

I've got a 2019 Beta 4T that I've had for a while, but don't get on with it anywhere near as well as I'd hoped. It's not as docile as I expected (yes, I'm at the old duffer end of the sportsman class standard of rider 😁) nor very easy to start when hot, and runs very rich. So, I took the carb off, and gave it to my local dealer to check that everything was right - jetting, needle, float height etc. to be sure. I refitted the carb, and it started second kick, then as soon as warm put the choke in, and stood back listening to how nicely it ticked over. Then out of the blue there was a loud 'clunk' from the engine as it stopped running, and now the it won…

On searching for "what oil...?" I expected a raft of opinions and an equal number of "not this again..!" responses. But alas no. So here goes... The manual says Bradahl 20w40. I have tubs of Shell Ultra 4t 10w40 (fully synthetic, top of the range shell bike oil) - is there any reason not to use the Shell? Hot viscosity will be as recommended, cold viscosity slightly thinner than the 20w40, but that is probably a good thing for cold starting. I can understand the logic of using a gearbox oil rather than an engine oil (such as no compromises for catalytic converters etc), but the manual does specify a multigrade. Pretty sure it is easy to over thin…
