Perun moto KTM 790/1X90 Top Luggage rack is our most versatile luggage rack. It can be used with various soft bags or hard top boxes, with or without OEM passenger grab handles – plenty of different configurations. It also can be used with optional Subplate for 790/1X90 Top luggage rack – 1X90 version. All these options require some clarification, so here we go.

Disclaimer: Perun moto KTM 790/1X90 Top luggage rack fits on all 790’s and 1X90’s. Although optional Subplate for 790/1X90 Top luggage rack – 1X90 Version also fits both on 790’s and 1X90’s, it is better suited for 1X90’s and we will soon launch 790 specific version.

1. Stock configuration

Stock KTM 1X90’s are equipped with OEM tail rack, mounted on top of OEM grab handles. 1090’s come with small plastic tail rack, while 1290’s come with larger metal tail rack. These two racks are interchangeable.

Photo of larger metal OEM tail rack for 1290.



Both OEM top racks provide very limited strapping points for soft luggage. Top cases can be mounted on larger OEM top rack, but only if additional adapters are used, so top case is mounted high.

It’s worth mentioning that both racks are bolted in same way, on top of OEM grab handles, directly to threads in steel subframe. Simple side view shows that top surface of the OEM rack (orange line) is not perpendicular to the bolts bolted into the sub frame (purple lines). This is since both small plastic and larger metal OEM top racks are cast, and top surface of the rack is at an angle compared to resting surface of bolt heads. It is nice because racks follow lines of the bike and are flush with stock seat.

Here is how tail of the bike looks without tail rack and OEM grab handles, just with aluminum spacers for better visibility. Threaded holes are under the spacers.

2. Perun moto KTM 790/1X90 Top luggage rack – basic configuration and brief overview

With our Top luggage rack, we wanted to add much needed versatility to carrying capacity of these bikes.

First goal was to add enough strapping points for various duffle bags and rack-less systems. With approx. 30 cm (L) x 29 cm (W) and slots all over perimeter, all sorts of 25-30-liter bags can be strapped easily. Even larger bags, 40-50-liters, can be safely mounted, but sides of the bag will overhang a bit. We added slots in the middle too, so smaller bags can be safely mounted too, in several positions.


Of course, like on all our racks, edges are chamfered and smooth, so straps last much longer.

Second goal was to enable mounting of top cases. There are predrilled holes for Givi and SW-Motech adapter kits. Unlike OEM metal tail rack, there is no need for additional mounting plate, just bolt hardware from one of these adapter kits to the pre-drilled holes and top case is mounted directly to our Top luggage rack. This way, top case is mounted low and it’s very secure – vibrations are minimized.

Third goal was to make it strong enough so it can be used to grab the bike and pick it up from the ground. To achieve that we used 6 mm aluminum, with side flanges adding stiffness. To keep weight low, there are large cut outs in the middle part of the rack.

Fourth goal was to enable mounting of Rotopax cans. There are predrilled holes for Rotopax mount, so adding 1 or 1.75-gallon Rotopax can is easy.

With all these different options available, we decided to offer two mounting choices in basic configuration.

Mounting instructions can be found HERE, and brief overview follows.

A. Top luggage rack and OEM grab handles

Our rack can be mounted on top of OEM grab handles, like OEM tail racks. Main difference is that our rack is flat (orange line) so it is perpendicular to the bolts (purple lines). To achieve this, there are spacers between rack and OEM grab handles, shorter at the back and longer at the front. This raises the front of the rack a bit and rack isn’t completely flush with stock seat.

Mounted like this, bolt connection is very strong. Positive side effect is that top case mounted on the rack sits perfectly and it doesn’t lean forward – this leaves more room for pillion.

B. Top luggage rack without OEM grab handles

Perun moto rack can be mounted with OEM grab handles removed. This is very convenient when rack-less luggage system, like Mosko moto Reckless 80, is used.

In order to do this, four additional spacers are used instead of OEM grab handles. We sell those spacers separately as KTM 790/1X90 Grab handles removal kit, for folks that don’t have our rack. But if buying our Top luggage rack, there is no need to purchase these spacers separately, as they are included with each 790/1X90 rack.

Again, check Installation instructions for details.

Here is how it looks – Perun moto KTM 790/1X90 Top luggage rack without OEM grab handles, with stock seat.

Notice that top rack surface is not flush with stock seat and not at the same angle. Depending on luggage setup used, this can be good or not so good.

But if Power Parts or some other taller aftermarket seat is used, rack is a bit bellow the seat. Here is rack, mounted in same way as on previous picture, but now with Power parts Ergo seat.

Again, depending on the luggage setup, this may be good or not so good.

3. Perun moto KTM 790/1X90 Top luggage rack and Subplate - 1X90 Version

For even more adjustability, we offer Subplate for 790/1X90 Top luggage rack – 1X90 version. It is a two-piece stainless steel bracket.

It mounts on the underside of the rack and acts as intermediary bracket, connecting Top luggage rack and bike.

Instructions can be found HERE.


So, Subplate bolts to the bike and rack bolts to the Subplate.

What it does? It puts Top luggage rack at an angle, so it is not perpendicular with the mounting bolts anymore. This lowers front part of the rack for approx. 10 mm. It may not seem much, but it is noticeable.

Here is the rack, mounted with Subplate, on the bike with stock seat. Notice that rack is now completely flush with stock seat and at almost same angle.


If the bike has Power parts seat, rack sits almost 20 mm lower than the seat, at almost the same angle.


In order to describe all this through numbers, we took some measurements. We measured distance from the plastic tail fairing to the top surface of the rack, in front and in the back. Here it’s shown where measures are taken.

Individual measures are not so important, difference between them is what matters.

So, when Top luggage rack is mounted with or without OEM grab handles (position related to plastic fairing is same either way), rear measurement is 14 mm and front is 30 mm.

When Subplate is used, rear is still 14 mm, and front is 20 mm – 10 mm lower.

For reference, when OEM metal rack is mounted - rear is 27 mm and front is 20 mm.

4. Weights

Since there are people who care a lot about weight, here are some facts.

OEM grab handles, including mounting bolts – 0.66 kg.

OEM small plastic tail rack (1090) – 0.39 kg.


OEM large metal tail rack (1290) – 0.93 kg.

So, OEM grab handles and small OEM rack (1090) – 1.05 kg and OEM grab handles and large OEM rack (1290) – 1.32 kg.

Perun moto 790/1X90 Top luggage rack alone – 0.98 kg, including mounting hardware – 1.13 kg.


OEM grab handles, without bolts – 0.59 kg.

Perun moto Grab handles removal kit (four spacers) – 0.06 kg.

So, Perun moto 790/1X90 Top luggage rack plus OEM grab handles – 1.83 kg and Perun moto 790/1X90 Top luggage rack without OEM grab handles (using Grab handles removal kit) – 1.19 kg.

Subplate is on the heavy side, including mounting hardware, it weighs 0.86 kg.

So, Perun moto Top luggage rack, mounted using Subplate – 1.99 kg.

When we were designing subplate, we still had in mind that some of us will grab Top luggage rack when pulling the bike out of mud hole or picking it up from the ground. So, we decided to follow safe route and use 4 mm stainless for Subplate. This way, assembly is very strong, but some weight is added. Again, idea was that no one will use this bike for racing and that luggage will be carried so 0.5 kg won’t make a difference.

5. Summary

So, to summarize.

Perun moto KTM 790/1X90 Top luggage rack can be used with (like on following photo) or without OEM grab handles (on second photo below).

It comes with spacers needed to eliminate OEM grab handles – buying Subplate is not necessary to eliminate OEM grab handles.


Mounted without Subplate, with or without OEM grab handles, top surface of the rack is almost parallel to the ground and front part of the rack is approx. 10 mm higher than rear of the stock seat.

This is great if top case is used and it is great for some rack-less luggage systems, i.e Mosko moto Reckless 80.

Subplate for 790/1X90 Top luggage rack – 1X90 version can be used only without OEM grab handles. It is intermediary bracket; it bolts directly to the bike and Top luggage rack bolts onto Subplate. Mounted this way (like on following photo), front of the rack is lowered approx. 10 mm and top surface of the rack is flush with stock seat and at the same angle.


This is good for some rack-less luggage system, i.e. Giant Loop Siskiyou.

It also looks a bit cooler as rack is lower and follows lines of the bike a bit better.




Maybe this giff with Perun moto KTM 790/1X90 Top luggage rack mounted with and without Subplate shows difference between these options best.
