    BETA USD FORKS

    No i didn't see it untill just now. It could be a bit to hard.... I went to one of the local trials group web pages as they have a lot of YouTube videos on learning techniques for trials and they also had a section on how to set up your suspension for Trials. I also thought it was about 1/3 sag both front and rear which i can get close to as i get just over 1/3 sag on the front. But in their set up guide it say 1/6 for the front. Here is a copy of it. There is more information they this i just cut the part about sag out. Here is a link for the full guide http://wdtc.org.au/training-tutorials/suspension-setup/ SAG SETUP ON TRIALS BIKES Setting up the sag on a trials bike is similar to that of a dirt bike, at least on the rear. As a rule of thumb, you want to use about one third of your rear suspension when you are in your normal riding position wearing your gear. The front is a bit different – you only want to use about one sixth of the fork travel. Most modern trials bikes have around six inches front travel and four inches rear travel but check with your manufacturer to confirm. For the front, simply place a zip tie around one of the fork legs to get a position when you are standing on the bike. Then suspend the front wheel in the air and measure the difference. If your bike has six inches of front suspension travel, you should have about one inch of sag. If you need less sag, use washers or spacers on top of the fork springs to suit. If you need more, then you need to buy softer fork springs. On the rear, measure from your rear axle to the rear fender while the rear is in the air. Get a friend to measure the distance once you are standing on the bike. You can spin the lower collar of the rear shock to adjust the sag as required. There is a tool you can buy to do this easily – some tap away with a hammer and punch but it does mess with the notches in the collar.

    BETA USD FORKS

    I was told mine was a 2001 but i check the frame number and it is 2000. It is interesting that there is 2 bikes that look very similar of that age in QLD. Mine has the headlight but no wiring and the front guard has no decals on it. I only bought it about 2 months ago. The guy before be only had it for a few years for what i was told and they guy he got it off was a bike mechanic..... but everyone says that lol I apparent mechanic rebuild the motor and i have checked the compression and piston and it looks to be true. But i think the bike has had a hard life at some point. I found a that the frame/tank has had a big hit and cracked one of the welds that had been repaired.

    BETA USD FORKS

    I remember reading that post the other day. Yeah mine is a 270. You are right my bike looking like a 2001 but it is a 2000. Someone has fitted the 2001 fenders on to it. I know that the 2001 had the option to fit the USD forks but from what i have been told non where bought into Australia. I would like to convert it back to the correct colours being the red and black but you can't find rear fenders at all for the 2000 and 2001 never mind being picking about the colours and i hate to even think about the cost ?

    I did think about fittng a spacer in there. I was sort of concerned that i was losing almost 1/2 of my travel with just me on the bike so i was a bit worried about bottoming out.

    BETA USD FORKS

    With a little bit of luck some may be able to point me in the correct direction. I have a 2000 rev 3 with the USD front forks. Being the only year Beta did the USD forks in the Rev 3 there is no information out there on them or parts. Although mine are working ok however they are a bit on the sad side of things and are sagging. All the replacement springs i have found so far say they fit Techno, Rev 3 and Evo but there is no information as to if it fits USD models. I know a few of the Technos had USD forks so does anyone know is they where the same as the Rev 3 and the spring's fit and are still available. Or if there is any other springs out there that will work. I believe i am just a little bit to heavy for the stock spring as with my gear on i am 85kg. With the stock spring i have 135mm of travel but with the max preload and me on the pegs it is sagging about 50mm with min preload it is sagging 62mm. The bike is sagging 22mm under its own weight. I have been told you want about 1/6 of your front travel to sag under your weight. So i only want about 22mm of sag with me on it Thanks for the help. P.s im located in Brisbane Australia not that it matters to much lol
  7. Hey mate, I also have a 2000 rev 3 that i pick up a few weeks ago in Australia. I was playing the front end today to try and set it up for my weight 82kg. I have manual from a later model rev 3 that i have been using as a guide to set it up. From what i can tell the stock springs are good up to 80kg. I measure the full travel which i got 135mm I have been told that you want 1/6 of your travel as sag when you a standing on the bike. With my pre load max out i have about 50mm sag when i really only want about 22mm. So i think im a bit to heavy for the stock spring as well as it is very sagged. I can't find any spec on our front ends. Or any other springs that fit the USD fork. All the after market ones i have found say they fit 2001 on. By any chance you measure your springs, length, width and wire diameter. Thanks mate Keegan
