    Hi everyone, I know this seems like a stupid question but I just bought a 2007 beta 250 4-stroke and I'm trying to find out what exact model it's is? VIN is ZD3T3020070000206 . From what i can find its a rev 4T, but then I'm seeing evo's and 4RT's and rev3 4T, etc etc it's a bit confusing 🤡🤯 thanks

    Greeting, As the winter weather sets in, I would like to get a good winter jacket. Sizing seems to be hit or miss for buying on line (was quoted a Large as a 38" chest ??). Ideally I would like to try on before I buy. I live in North Wales but am travelling up to Livingston on Saturday 19th Sept so could take a "short" detour for the right shop. Any well known ones / suggestions? Rob

  4. Evening all, Can anyone recommend a trails training ground (pay and play) area in between Stoke on Trent and Stafford? I’m looking for somewhere halfway-ish between where me and my mate live so we can hook up and just have a play about. many thanks.

    My brother has a 1990 or so 240 climber. Whats the trick to pulling the clutch basket. It does not appear to be like a jap dirtbike where you can use a tool to hold the basket from spinning. The nut spins along with the plates inside the basket. How do you keep the motor from spinning so you can break the nut loose. btw is it a normal thread or reverse thread?

  6. Started by diagnosis,

    I was wondering if anyone could help ID a pair of handlebars that came on my Yamaha TY175 when I purchased it. I’ve recently swapped to an OEM set, but curious about the old ones. They have a yellow zinc plate finish. It’s been suggested they may be Bernie Schrieber, or Answer handlebars possibly, but there were no identifying marks other than sticker residue, left over. A photo on the bike just after I picked it up. Mainly just personal curiosity as to what they may have been. Thanks!

  10. Hi everyone I'm hoping someone could help, does anyone happen to know the dimensions of the seals in the Grimeca rear caliper on a 2016 Beta Evo ? I've bought a new piston/seal kit and when fitting it pinched a seal 😞 and don't want to pay £45 for another kit just for the seals. Cheers

I have recently got back into it ( weeks ) . I bought a Yamaha TY250 and had a bit of fun and was amazed how much easier it was to ride due to the weight etc . Well , I just bought a 2007 GAS GAS TXT 280 , and boy is that a different kettle of fish again . I am amazed at how much easier the control and balance is . I am truly a convertee . Had a bit of a play and am now Sold on riding modern . The amazing thing is how much easier it was and how much more fun I was having playing around . I h…

  12. Hi, sorry more questions. I'm trying to figure out my fuel system on the 2007 rev 4T 250 4-stroke. Mostly out of curiosity so if anyone knows them and could fill me in I'd be very thankful. OK in the manual the fuel tap has a weird looking fuel tap? My doesn't have the same. I'll add some photos. Mine also has a fuel outlet at the back of the tank with a weird nob on it? The fuel outlet on the side of the tank doesn't seem to have an on/off? The fuel lines go into a little chrome cylinder which I'm guessing is a pump? It plugs into the wiring loom. The block connector the feeds it has 2 extra wires that have been cut? It also has a hot start cable that runs into the botto…

  14. I have posted in the stolen bikes section so please forgive me for posting again here. It's with great sadness that our next junior academy trial on the 22nd July (and all future events for that matter) has been cancelled after the clubs OSET BIKES WERE STOLEN from one of our committee's houses in Halsted overnight. The bikes stolen were a 16 racing and a 20 racing model. Can we please share this posting far and wide and keep eyes and ears peeled for any information that may lead to the recovery of these bikes. As you know these bikes were for the youngsters of our community to use and ride for just £10 a go and these thieves have robbed not only the club but all of …
