For those of you who don’t like a center stand, some useful gadgets exists to replace it, either out there on the trail or in the garage. One that works is the EnduroStar TS3 Trail Stand, a very compact tool that can squeeze anywhere. $40. BDCW even drilled holes in their skid plate to accommodate it.
All the seats below are interchangeable between the R, the S and the Rally. The R seat and the S seat in high position are exactly the same height if installed on the same bike. In lower position the S seat height drops by 20mm.
Note that the seat height is not everything. The S seat is wider than the R seat, making it harder to slide and reach the floor, so on the same bike the S seat will seems higher. Same thing about the low seat, it is only 5mm lower than the S seat in low position, but it is narrower, making it easier to flat foot. And the same for the tall rally seat, standard on the Rally, it is tapered at the top, making it easy to slide sideways to put a feet on the ground, despite sitting higher than all the other seats.
Also, contrary to some other models, and like the heated grips, the heated seats are not controlled in the bike’s menu, but simply by push buttons. The driver’s one is supposed to be installed on the removable tab on the right side of the dashboard. See the manual.

* The seat height for the rally are questionable. KTM web site give it at 910. KTM Rally manual prints it at 923. Same for road clearance, the number are quite vague: KTM website list it at 263mm, same as the R, whereas the manual list it at 303mm which is adding 30mm height to the whole bike when only the fork was made longer, and as it sits as an angle it should not rise the bike that much. The numbers in this table have been recalculated assuming that the seat height of 910 is correct, and the ground clearance in the model table is derived from this as well. The values in the manual don’t correspond to anything that makes sense once compared with the peg/seat distance on the other models which should be identical. This is not helped by KTM giving the seat height for optional seats in differential values, which are probably rounded, or presenting marketing material with numbers rounded the other way, making it it close to impossible to get the right value in this table.
Rebel X Sport propose a rally seat cover with logos on all sides to put on the R seat. This is a permanent transformation, the original cover is completely removed.
Seat concepts offers a bunch of one piece seats, with different heights, for $300 to $320 each. Warning, the low version has been described as “might as well be sitting on a piece of wood” by an owner who got rid of it.
Corbin also makes a seat for the 790, with optional heating, and a lot of option in their seat configurator (from $540 depending on options)
Tampering with the catalyser will make the bike illegal to ride on the road in most countries. Plus it’s bad for karma as the bike will be polluting more.
This said, you can find vendors selling straight pipes to replace the catalyser. But, be aware that the people at Coober ran the bike on a dyno with and without the catalyser and decided not to offer such a pipe due to the loss of power. They are working on a pipe that will replace the catalyser but still provide the necessary back pressure to avoid the power loss. (Coober confirmed their recommendation recently)
Unless you have access to an engine engineer, a dyno, the ability to make your own ECU plus some very expensive hardware to measure pressure and temperature you probably should keep the catalyser.
The main reasons to replace the original exhaust can is to gain space, weight, change the sound, or simply for esthetic reasons. Power or torque gain will be marginal at best.
You will find below, in alphabetical order, some replacement you can install. Most (all?) are lighter than the original can, and some may have the ability to remove internal baffles to make more noise (with no minimal improvement on performance, if not negative effect).
Note also that a new exhaust may interfere with luggage options, or passenger legs. Or even melt the turn signals!
Akrapovič p/n 63505979000, about £875. Availble as an option from your KTM dealer.
This muffler can be modified to remove the baffle by drilling one hole and unscrewing a screw. This is a picture of the necessary hole. Please note that the dimension of 32mm measured back from the end of the exhaust to centre of the necessary access hole to be drilled is not 100% correct. See this post or this video with additional photos for exact measurements. A plug can be bought from Akrapovič to close the hole, and it is referenced by KTM (P/n 76505099050), about €3.
GPR have 31 different slip on(!) you can order. And an optional decat pipe. GPR published a video showing some of these models mounted on a 790.
Buyers beware: there are a couple of issues:
Some models are not well designed for the 790, they are generic models that can be bolted on. This lead to disastrous results.
Also note this comment on this post by Raymond Wilson: “I have GPR on my 1290 Super Adv […] the GPR mounting system with the external collar that wraps round the pipe is crap. I see they’ve used this method on the 790 Adventure exhaust and this alone would deter me from ever buying one”.
Rade garage works with Sharon and offers a Rally style exhaust requiring the removal of the catalyser . €330. Not street legal. 3kgs lighter than original.
Wings. Coober couples it with an ECU upgrade. 2300g, 1.35kg lighter than the original exhaust. Includes removable DBKiller and spark arrester. €630 with the rear heat shield included. Heel heat shield is extra, €52. It is smaller than the original or the Akra.
Also Yoshimura has developed its own slip-on. Two different DB killers and spark arrester can be purchased separately. Saving are less than 1Kgs. $600. Just a heads up, the Yoshimura RS4 exhaust sits taller than the stock making the installation of some pannier racks impossible. Also with the added height the blinker get hit by heat from the exhaust gasses.
You can replace the annoying bolt holding the windshield in place by a nice one, but it’s $15 which is a tad expensive for a glorified M5 bolt! In a pinch a cut down GoPro casing know can do.
Another accessory is this innovative little doodad (€35) that goes between the the original holes and the windshield to simply move it into a more vertical position. Another similar device is available to 3D print (Website in Swedish, use Chrome translate feature to read it)
A lot of people are very satisfied by little blade deflectors on top of the original windshield.Too many of those to list here.

Puig has a touring screen available, €103, larger than the KTM options in clear, smoke and dark smoke colors. There is a one paragraph review at advrider: first impressions are: good for the road, but wobbly off-road.
The bikes are coming with a standard paper filter (P/n 60306015100). A replacement foam air filter is available for dusty places. P/n 63506915000. Feedback about this foam filter is less than stellar, it needs grease to fill the side, and is hard to put in place (as all foam filter this filter needs to be oiled).
Alternatively, KTM offers a foam pre-filter system, replacing the filter cover and the two trumpets (p/n 63506915144, €60). Due to its size, it is not compatible with the dual seats, and not compatible with the alarm.
For sand, this prefilter can be topped off with a pre-pre filter (p/n 63506922000, €20).
Rottweiler offer two different replacement systems for the air intake. The first one is similar to the KTM prefilter (but predates it by at least a year!) as it replaces the filter cover and removes the snorkels. It’s called the PowerPlate and cost around $90.
They also offer a complete replacement airbox, with a foam filter. Available in carbon (Rally Edition Full Intake System $650) or rotomolded plastic (Pro Edition Full Intake System, $350), in different finishes and colors. They claim up to 10hp gain by just installing it.
Unifilter has foam filters available. 100 A$ a set of two. Those are the EOM fitments in Australia. With yellow and green foam in a reusable metal insert. They also offer socks that can be set inside the air intake for additional protection (but those are intended for off-road only). There is a lot of info about unifilter on this FB thread including a comment from the designer of the part, Myles Gooch, explaining its proper care :
[…] I designed the Unifilter Australia Filter. You don’t need to grease the foam inserts. You just need to make sure you insert them correctly. Inserts the green one first. Make sure it’s fits nicely, then insert the yellow layer. With the 790 you need to treat it like a regular dirt bike when riding in dust. The location of the intake is similar to a dirt bike. You should inspect the filter every 150-200km when riding in dust. We supply the extra foam insert due to the intake setup drawing lots of dust from the back wheel. This allows you to change it easily when the conditions require it. Always make sure you use a quality filter oil. Avoid spray on filter oils.. always use grease on the seal and you will never have an issue. You can use the sock style pre-filters when riding in dust to increase the service interval. These should be oiled to work effectively too. Cheers
