The TW Achilles' heel

To me is the tail strength and cargo capacity limit, especially if I'm headed out camping. I noticed Yamaha put a 7lb limit on the stock fender mount which to me was useless. I then got a back rack that I liked from another member. It came with a mounting bracket that not only strengthened up the tail but had extra mounting holes for added accessories if wanted. I love the rack but figured with a decent amount of weight kicking up and down all day long may not be best for that weak tail section.

So came up with a solution that should work just fine. Headed down to the local Hardware store and picked up some 1/2" DOM pipe and a piece of hardened 3/8 threaded rod. Made a little bender, bent and cut the tube. Ran the threaded rod inside the tubing. Pulled my passenger foot pegs because I'll never need those and bolted everything together.

your support bar is making a debris trap with the tire. you are in for serious trouble my friend. Look how this company has solved the issue of tire wedging. Get that bar clear of the tire side walls. TW200 Rear Rack – CycleRacks

I like it.

Like David, I like how my Cyclerack mounts, but on the Cyclerack that forward strut is a pivot. There is still a lot of force trying to crack that rear mount and stressing the subframe of the TW.

Your strut is triangulating the system and trying to transfer some of that rear luggage weight forward and lower down. Good job.

I may steal the idea but with a bit of an "S" curve, going farther back acting as a pannier support and muffler guard.

My tubes are eight inches away from the side of the tire on both sides.

That is very cool indeed! And certainly a cheap and easy DIY solution that just about anyone can build/install. Well done.

Its a great fricking idea that anyone can do without needing a welder and a Bridgeport mill.
Looks like it might work with saddle bags too.
Maybe if you ran down a moose and his antlers got stuck in there it might be a problem. Or maybe an alligator or agitator. I dont know.

if you ever get a chace to see the rear frame section on the BW200 which the original CycleCracks was designed for it has a very sturdy dual frame section all the way to the tail using twice the diameter frame tune as the TW

I'm not sure why they chose to cheap out on that rear frame section but I have always wanted to build a hidden rear under structure that could support any size rack from 6 pack to quarter elk

For Today, here and now the Happy Trailer set with SU panniers has the best TW frame support I've seen so far

If a bomb proof rear ADV rack system was ever designed and built you could sell a tone of them

Those sub-frame cross bars seem to be a weak spot for loaded TWs. Hmmm, I wonder if someone could come up with a heavier duty cross bar or aux brace? Bradley?

After breaking once again a home repaired cross brace I welded in a superior unit of bent and thread tapped bar stock originally made by forum member VanillaGorilla. Good solution but was from a limited production run years ago, no current commercial offering that I am aware of. However it is simple and can be replicated with simple fabrication skills.

Most likely due to it being a Dual Sport bike, whereas the BW200 was strictly off-road. Back when…generally DS bikes weren’t carrying anything heavy on back. Plus…weight savings, albeit not much.

In the way back machine, there’s a great posting on simply re enforcing the sub frame. Pretty much a must do if your loading up. Might have been “Ronniedog”?

Did anybody ever made a mod that could use the space under the seat?...

Like a seat that could open rising up and that's basically a case, plastic storage that attaches around the frame.... like scooters have to put the helmet and other stuff...

I just had my TW, but im used to scooters, thats the main non-pratical thing by far, lost stuff 4 times already... noteworthy, 2 cans 0.8L of 20W50 somewhere along the highway... hahahaaa

That wheel with the suspension isn't going up to the seat and there's a good 20Liters of stuff to put there, that case could also take the shape of the wheel to go deeper on the sides.

Like a lot of small moving things that don't need to be properly attached... a huge plus is that it's the best place to put stuff center of gravity-wise.

There could be compartments in there too, either hard or just side attach cord nets could be snapped in the configuration you want, just to prevent stuff from moving around... could be key lockable too...

Just an idea, seems to me that's a nice one, i just wont ever do it... lol... i guess to do that properly a company would need to CAD that and do the plastic mold for it.

It's certainly a valid thought. But remember, this is not a scooter... it's a goat, or a donkey. that space under the seat is to protect the battery and leave clearance beneath for wheel travel and FOD, and the seat is screwed into place. If you need cargo space, there is literally... I mean literally, too many options to count on your fingers and toes. Hell, half the fun is showing off the ridiculous ways you can strap shit to the TDUB. This is not the bike to think too hard about.

Obviously this isnt a scooter, i just dont see how thats relevant... cause it's not a scooter it cant have internal storage space??... it's more like a tractor if you ask me, but again its meant to carry stuff, thats more of a reason for more storage, its also a trail thing where its shaking so things can fail and balance is primordial, so more of a reason to be internal and near the center amap.

protect battery > no change in that, if fact it would be double/triple wall protected.

space for wheel > still there no change on that.

FOD > cant find out what this is...??

seat screwed > doesnt matter, that seat can be screwed on that system.

if you need cargo place, many... > yeah sure, just not as practical, more is always better, internal is safer and more stable, better for the center of gravity than strapped stuff far back or in front of headlight... +you dont always need this, not everybody at least, personally thats 15minutes 3x a week to bring grocery stuff and such, and a constant case is ugly in my opinion especially if its 95% there for nothing.

remove fun of ludicrous strapping > it doesnt, this would be meant for a bunch of small objects, all repair tools for example or your lunch, if i need to strap a fridge or a donkey on it, thats still gonna go on the back and then here ;-)

Something like that in fact if that makes more sense visually.... and the seat could open rolling to the side, like flapping to the right upwards, with a keylock on the left.

what im gonna do for now is a foldable plexiglass box on the rear rack, like 4 flaps that folds on themselves and disappear from sight when not it use... working on it right now, but something like that.

Don't get defensive. You asked a question and made some comments and I responded respectfully.

If you feel like you can find more storage under the seat, great. They do make some quick release seat pins so you don't need a wrench to remove the saddle. I don't know if i would like a tip away seat... I want things mounted firmly. If you come up with something genuinely clever, show it off... you might have some folks here following suit. I like the idea of keeping seldom used repair items under there... you mentioned stashing oil there and I think that's a great idea. I just don't think there is as much usable space there without interfering with something else, or being impractical. Still, I am going to have to take another look and see if this idea has merit.
