November 7, 20232 yr Always wanted to ride trials, but never have. My hobby is old motorcycle restoration, typically British. Past years raced vintage MX on a 1967 Husqvarna 360, stopped in 2005. Now wanting to ride a 72 Sherpa T model 92. recently purchased a Sherpa Bultaco in progress, due finished by early 24. I am 76" tall at 175 lbs and I have my first helmet from 1969 (no foam/all failed). I am concerned about being too tall for this sport on a vintage Sherpa. Also concerned about going back to kick start.
November 7, 20232 yr Being tall is no reason not to ride. You can still get higher rise handlebars or buy some bar risers. The 1979 world Champion is well over 6 foot high. You can also move the footpegs back and down with some modern footpegs which makes them ride a lot better. Once you have the knack they are easy to start. They do like to be timed regularly though. Go for it!
November 8, 20232 yr Author Looking at mods for this 1972 Sherpa T 92 to make it fit my novice ability. I have used ROX risers in the past on on my 701e Husqvarna (now sold) This type of rotatable riser allows the bars to reposition straight up rather than angle back with a stack type long bolt riser. I don't see any ability to lower pegs as the foot peg mount appears welded to the chassis.
November 8, 20232 yr In fact I think Classic Twinshock fits tall riders better then modern. Find correct handlebars to suit you. Risers can be dangerous. You may also change footpeg position for better stands and also fit modern footpegs. Original Bultaco are outdated. Cut the original attachments and weld on new. We all do.

January 2, 20242 yr Author Need tech specs please. 1972-3 Sherpa model 92b. what is the OEM shock travel? Not wheel travel, not axle travel Eye to eye, shock travel dimensions, exposed chrome shaft length when fully extended?

Not wheel travel, not axle travel Eye to eye, shock travel dimensions, exposed chrome shaft length when fully extended? So here's a photo of a Spanish Betor trials shock from back then. I have no way of knowing if its actually from a model 92 or not but I do have quite a few and they all have the same length shock shaft. Some have this type of seal retainer and others have a different type of seal retainer. Edited January 3, 20242 yr by feetupfun
January 6, 20242 yr Author Thank you feetupfun, your information and pics are wonderful. I am now using 360mm Betor gas shocks and wanted to understand how the original Betor shocks limited travel. The new shocks 360 with 95mm travel just barely clear new white plastic fender. Edited January 6, 20242 yr by tokig

Another factor in rear tyre clearance is that the rear competition tyres in the 1970s were nowhere near as tall as modern competition rear tyres
