I grew up around Yellowstone, Cody, Wy. actually, and know about having the crap scared out of me too by bears.

I would worry about any 2 stroke trials bike long term doing any sort of enduro. I dont particularly like 4rts, but you will at least know the gearbox and engine will stand the abuse

Hi all, Just stripped my forks down on a Montesa 4rt and replaced lower and upper bushes along with new seals and oil. My question is to do with the right fork leg: Do I fit fork cap with fork compressed or extended? Im thinking compressed as that’s when you measure the oil height and it will work better with controlling the spring rebound. I can’t see this info in the manual. Pic of both legs ready to fit with difference in length.

Thanks, Konrad. ACU currently aren't keen on electric Enduro or MX bikes- and of course it's the range issue. I want to be able to do a lap (with a seat), come in, refuel, go again.

Thank you for the input. A Beta Alp (or Freeride, or equivalent) is no good to me as I can't use it as a trials bike. I'd keep my Enduro bike, as I do actually do the odd motocross race on it, too, and today was riding quite happily at a motocross practice track. Green laning doesn't appeal to me, I'm looking for a trials bike that I can use at for trials... ..and then put a bigger tank and seat on to do Enduro/hare & hounds practice. I know it's a knife to a gun fight, but at least it does one thing well.

This is a topic near and dear to me. I keep spreadsheets with gear ratios for a variety of bikes. Modern trials bikes will all have the same problem, a wide gap between the "section" ratios and the "loop" ratios. The most even spacing I've measured among trials bikes was my old TXT321. Never had that gearbox apart, but counted motor revs per wheel rev as: 39.25, 33.75, 26.50, 20.75, 13.25, 9.00. Typically, a 6-speed box will offer a slight improvement over your Sherco's 5-speed. FWIW, I've discovered that single-speed electric trials bikes work really well as a technical trail bike.

I have a TRS but have never been more than about 20mph on it. Have you thought about a Beta Alp? You can do long distance trials and green lanes and so on. I keep looking for one but they are hard to find and the new ones are "rally" type to cash in on the adventure bike fad. I have a CRF250L but it would be useless for trials. Great fun though.

Hi all, for context/back story I have a 300 Sherco trials bike and 300 Sherco 4-stroke enduro bike- and struggle to find time to use either! My trials riding is Novice level and living on the London/Essex border, my 'enduro' riding is the odd enduro practice day or Hare & Hounds practice day. Generally tighter stuff, and again I'm Novice level. I can't justify having both bikes, so am considering a trials bike with long-ride kit. A Honda 4-Ride is the logical option but I'm a little wary, so that leaves TRS, Beta, or Sherco. My Sherco has a biiiiiiig jump between 3rd and 4th, which isn't ideal. How do the TRS and Beta compare?

4t impeller is different than the 2t

You might look into "Nils Clutch Trial" oil its specs are very close to the ELF oil and is worth considering in my opinion. Specs for comparison: ELF 40°C 21.4 100°C 7.0 NILS 40°C 24.7 100°C 7.5

Also try performance engineering services. Pes ccm.

Joe Maxwell Engineering might be a good place to start. CCM's were originally based on the BSA B50, successor to the B44. http://joemaxwell-engineering.com/

Correction. I see that I said "left side Crankcase cover" I meant right side.

I just went to , https://www.suzukipartshouse.com/oemparts/a/suz/50d392fdf8700229982f2f3f/crankcase-cover, It appears to show two different left side crankcase cover, both listed under TM250. It also states, "Diagrams Shown are for U.S. models". So that explains it a little bit. So there were definitely two different styles made. Same year? Mid year change? I don't know. Thanks. LaVern

Shakenstirred, Clearly it has the right side lever. I wonder why Partzilla and Babbitt's don't show that, or maybe I just don't see it in the parts diagrams. Thanks for the photo. LaVern

Brill thanks mate

Fair play, that shows why i'm the one asking badly worded questions haha

I call that a single speed gearbox.

1974 Tm250

If your garage is like mine it’s got sawzall, grinders, etc for anyone with access to use. Lock your garage, put up cameras and take out insurance on the bike. Everything else is up to fate.

Might anyone know of a lower compression piston compatible with the B44?

Fill and drain bolts are both M12 x 1.5

I just spent quite a bit of time looking thru the OEM parts, of Partzilla and Babbitt's and find no parts fiche that shows a TM250 with a right side clutch lever as you show. I can see in your picture it's a Suzuki side cover. I wonder if like Yamahas the Suzukis were manufactured with differences depending on where they were shipped to. I'm in the USA, where are you located? Thanks for this conversation. I am finding it quite interesting and educational. LaVern

It doesnt have a gearbox mate its an Epure Race 21 so its just the clutch The drain plug is this one I just want to know if i can get a generic one the same rather than having to get a specific one ordered in.
