Yea the 200x, 250r, and 350x all start with better suspension mainly because they were designed for more extreme riding and all have chain drive. The 250sx is the sportiest shaft drive that I know of. I heard/read there's some trx models that were made within the last like 10 years that were sport + shaft drive but know little to nothing about them, I think they where 250cc.
The auto x is a pretty common build, never heard of this super x, but it seems to be the same concept except using a trx 200 series engine instead of an atc one. I looked up the models for 86 because I didn't recognize the model + year combo, I suspect it's the TRX200SX. The actual TRX200 (no letter) was released in 1990 and only lasted till 1991. I think the TRX200D is effectively the same machine (91-97). I've looked at the 2000 and older machines way too much in the last year lol.
If you want to talk about tanks, check out the ATC250ES =) pretty sure that was the heaviest Honda 3 wheeler, something like 100lbs heavier than the 250sx... actually let me grab the specs.
250sx - 364lbs
250es - 406-410lbs (guess I overshot a bit for my guess)
350x - 320lbs
83-85 200x - 282lbs
86-87 200x - 278lbs
81-84 250r - 302lbs
85-86 250r - 289-291lbs
Just for fun, here's a "smaller" shaft drive machine...
84 200es - 375lbs
Since weights are kind of interesting to check out side by side I compiled some data together from
service manuals and brochures. I just did a quick run through the ATC and FL models since there's a million TRX models lol.
