Depends on the type of fuel delivery it has. If it has a constant velocity carburetor it can handle a wider range of altitude but you might have to lower the needle jet in order to lean out the mixture if going up near timberline or above. In a regular carb you will have to drop the needle more often to get the optimum mixture. Don't know if the new ones have FI, if so they shouldn't have any problems. Haven't looked but there might be You Tube vids on how to tweak for performance at altitude.How is the 125 at high elevation? A CT 125 on a hitch haul could be better than an atv on a trailer.

When I lived out there I ran 60's vintage Honda bikes from Denver elevation to 13K'+ and when they got up to places like climbing out of Leadville and over Mosquito pass they wouldn't pull a greasy string out of a cat's butt if you didn't lower the needle in order to lean out the mixture.
I haven't had any problems with the carburetor so far. I'm usually riding between 6000-9000 ft around our place. The factory carburetor (1987) was completely gummed up and I replaced it entirely with a cheap $45 Amazon one. Runs great and I only use the choke on the first startup of the season. Had to adjust idle screw twice though.TW200 is carbureted. Any elevation issues?
I'm having a real hard time letting go of the idea of a mini bike geared well down and adjustable carb. It's not a smart idea, but...
A triumph elk bike! Now that's one heck of a ride! I'd be worried parking her along some backwoods dirt road. Those pipes look a bit mad max-ish. Agree for routing around to different areas, nice to have the cc's..View attachment 318962
If I were to do this again I'd go with the TW200. The Trail 90 is an awesome little machine, but covering highway to get to hunting spots takes a little more juice.
Those Fat Cats were awesome and sucked hard at the same time.I had a little suzuki fat tire trail bike as a kid, I rallied that thing all over the world.
@theat I'm impressed, did you use a sled or just strap it on or backpack? I've considered getting one and flying it into a few spots, it would be a game changer.
