August 30, 20169 yr Having bought a trs recently and previously having a jotagas the clutch is harder on the trs , now wether this is due to my trs being new and the jotagas being 2 1/2 yrs old I don't know , it's basically the same design as a jotagas , I may swop the bel vile washer ( which provides the tension in the clutch ) if it's the same as the jotagas , and see how that feels. Was struggling at the weekend with the bite point being very close to bars , so it took a lot a lot of pulling in to clear , maybe me getting tired ? Not sure .
August 30, 20169 yr The Jtg clutch was great for most riders , but the factory riders felt that it didn't grab fast enough for steps and big stuff , not that it would effect 99 percent of people. They had to upgrade them. I would guess that this is the reason why the trs clutch is stiffer as they have upgraded it. The factory riders run with standard clutches as they're strong enough.
October 22, 20169 yr Clutch is one of the virtues of my new 300 TRS..! Smooth as silk, effort is better, softer pull than my ex sherco
October 22, 20169 yr Author Yeah, the more recent bikes have a smaller clutch pack. Feels exactly like a GG now.
February 21, 20179 yr I rode a TRS 300RR this last weeken here in Taiwan I thought the clutch to be much stiffer to pull than my 06 montesa . The bike is light the guy that owns really like it but if i had it I would have to do something with clutch. What do you do for such a hard pull on a TRS? I watch this guy ride hes having arm pump holding clutch shakes it out and keeps on riding i think he's around 17 so can't blame age.
February 21, 20179 yr I've just bought a 2017 standard 280 and find the clutch to be fine, light and smooth.
February 21, 20179 yr Author The early ones had a higher effort. They eventually dropped the size of the clutch pack and it decreased quite a bit.
February 22, 20179 yr Who would have imagined, as we spent five minutes adjusting the spring tension on our Bultacos to get the plates to lift square back in the Seventies, that progress would be such that this far in to the 21st century people would have to be messing about with emery to get a clutch to work properly? Surely modern design and, more to the point, production methods, can do better than this.
February 22, 20179 yr Author Erm... working properly and changing pull effort are two entirely different things. And something tells me the clutch on a modern TRS is better in just about every way than an old Bultaco, but maybe I'm wrong...

It's not working properly if you can't pull it, or have I missed the point ?
February 22, 20179 yr Correct Ross. Regardless of the power of the works rider's finger a clutch should be designed and produced to a consistent standard (which seems to be the nub of the problem here as some clutches would appear to be light and others not) such that it works to the satisfaction of the target purchaser within his expectations related to contemporary standards. Which is what the 1970's clutches, except probably Ossa, did. In that context a Bultaco clutch appears to be "better" than some described by users above. If pack thickness is critical then that should be addressed on assembly at the factory, not left to the metalworking skills of the buyer.
February 22, 20179 yr Author Yes, and as I've mentioned: Early TRS's had a thicker clutch pack. The pull was commensurately harder. They got the feedback, and later editions had the pack height reduced, and now it's quite good for the avg club rider.
