    Looking to replace the shocks on my Penton/Wassell Trials Bike. The bike is competed with regularly. Right now I have a set of old Betors I took off my Ossa MAR. I'm open to all suggestions. Just looking for a modern replacement verses rebuilding an old set.
    Any advice will be appreciated.

    I have had great luck with these guys. I've had a couple sets of the NJB shocks. They will set them up for your weight and ability.

    I've ordered a few bits for my Bultaco from Sammy Miller products and found them very knowledgeable and helpful.

    Depends how serious you are about your riding. If you are simply riding for fun, and not very competitive then NJB or Betor shocks will be fine, but these dont work that great and are not rebuildable. At the other end of the scale are trials shocks made by Maxton engineering here in the UK, but as these are around £500 only for very very serious riders. Around about the best balance between cost/function are Falcon shocks which can be rebuilt and work an awful lot better than anything from NJB or Betor (available from B&J Racing in the US).

    Twin-shocker, Can you explain how much better the Maxton shocks are and why? If money is not an issue, what separates them from Betor, NJB and Falcon? Good Vintage MX shocks are VERY expensive. But there is an obvious difference the first time you ride with them. Is it the same way with the Maxtons on a Vintage Trials bike?

    Also, maybe someone has some advice for my MP forks. Would be nice to smooth those out as well.

    Thanks folks.

    The difference between Maxton and things like Betor or NJB can be compared to the difference between a worn out std shock on a road going mono-shock bike, and a brand new Ohlins properly set up for specific application and rider. Maxton can also supply cartridge inserts to fit any type of 35mm forks. Good suspension is a big help for expert standard riders on competitive TS bikes, and Steve Saunders won the "P65" Scottish last year using Maxton suspension on his bike.

    I bought NJB Experts for my Sherpa T. At the time I was planning on riding AHRMA events, they seemed to work fine for their sections. Now I'm riding modern events on the Bultaco and really wish I'd spent the money for better shocks.
    So you're intended use, and level of competition both now and in the future, needs to be considered when you're shopping for shocks.

    I know it's a little off the topic, but I am considering running my Sherpa T (M49) in modern events as well. Can you share your bike set up, and maybe photos of your Sherpa T?

    Thank you,

    Iamotovita, You bring up a great point. Although I ride in the vintage class, we vintage guys ride the same line as the modern bikes. NETA is a Trials club. There are only about 5 of us that ride Vintage. So we ride the modern "B" line. Not easy, by any stretch.
    There are also no break down in classes. Just "Vintage". Air Cooled, Drum Brakes, Twin Shocks and any year.

    I encourage you to ride some modern events. The lower classes should not require a modern bike.
    I have lowered my footpegs and cut the rear frame loop off my Bultaco, as well as fitted longer shocks. I'm 6'1" tall and those mods helped me considerably.
    My M199 is a generation newer than your M49 and was well thrashed when I got it. If your M49 is in decent, original condition it might be better appreciated in it's original form. I don't know anything about your local Trials clubs but I think there should be a class appropriate for your bike.

    I am in the same boat with a TY175 I am restoring I have a set of originals that will get me by for a while but being a bigger lad 6+ 220lbs am I better off biting the bullet and ordering a set of Falcon's from BJs or looking to rebuild the originals(hard to find kits) Thanks in advance for the insights I am planning on entering some vintage events once I get the bike restored:lol3

    It is possible to rebuild original shocks, but unless they have had very little use from new this certainly isnt simply a matter of re-newing the seals (which in general are easily available, from industrial bearing suppliers), and in most cases the damper rods will need to be replaced. Add to this the fact that OE shocks perform pretty much the same as bottom end replacement parts such as NJB or Betor, and quality replacements such as Falcon seem to be a much better option.

    I would avoid B&J racing. Great quality parts but ripped me off on shipping and very poor customer service. Also took 3-4 wks to ship my order. speed&sport has much better service
