    Perun moto is producing rear top racks for KTM 790/890 Adventure bikes since the launch of KTM 790 Adventure back in 2019. 

    During these years, we gathered a lot of experience with these bikes and these racks and we did several design updates. We had a choice - we could made a decent and relatively cheap rack or we could offer an outstanding feature-rich rack for a moderately high price. We opted for the second choice. 

    Below are just some of the unique features of our Billet racks, shown on the example of KTM 790/890 Billet rack - Large. All applies to KTM 1X90 Billet rack - Large (2013-2020) and Husqvarna Norden 901 Billet rack - Large.

    • 3D milled spacer platforms on the underside

    Main difference between cheap copies and Perun moto Billet racks is in the unique underside of the rack. Spacer platforms on the underside are milled at an angle, relative to the top surface of the rack. Angle suits the bike perfectly and that is why we offer two almost identical racks, one for 1X90 bikes (2013-2020) and one for 790/890 bikes.  Racks are 100% same, except for the different mounting angle. Additionally, we offer Husqvarna Norden 901 Billet rack - Large, which is same as 790/890 rack, but with different spacers. 

    Of course, holes for M8 mounting bolts on the upper side are also countersunk at an angle.

    This puts the rack flush with the stock seat and at the same angle. 

    This also makes the rack light - rack alone weights approx. 1 kg, and just a bit over 1 kg when mounting hardware is included. 

    Installation is a breeze, very elegant and with minimal mounting hardware - just four bolts and two spacers (plus four additional spacers if grab handles are removed).

    • Support for stock grab handles

    Rack can be used with or without stock grab handles. If used with stock grab handles, only two spacers are used in front and no spacers at the rear. Rack fits "into the handles", and creates one compact assembly. It sits very close to the grab handles, almost on them, so grab handles will be supported by the rack, when they are being pulled up, which will prevent large leverage. These grab handles are known to be brittle and without the rack supporting them, they can easily break.  

    Also, rack can be mounted without stock grab handles. Additional spacers required for this are supplied with each rack, as a part of the standard hardware kit. Since rack is mounted at an angle, it sits very low and flush with the stock seat. 

    • Top case support - Givi and SW-Motech

    Rack is perfectly sized to offer good placement for the top case and for large duffle bags. Givi or SW-Motech top cases will sit ideally, so there is a room for the pillion, yet the top case don't overhang to the back too much. 

    For easier placement of the top case mount hardware, there are shallow pockets milled over the appropriate holes. This makes the installation easy and leaves little room for error. 

    And for the better fit of the rubber grommets needed for Givi top cases, there are pockets on the underside of the rack. This way, the thickness of the plate is just perfect for these grommets. Without this feature, if rack plate was to thick, grommets would be to tight and they will eventually snap and fall off. 

    • Slots and slot placement - support for rack-less systems

    Almost every slot on the rack has it's purpose - it is there to provide easy installation of one of the major rack-less systems. These slots will make the mounting of systems like Mosko moto Reckless 80 very easy. 

    Also, all slots are chamfered and then additionally rounded by powder coating, so the won't bite through the straps. 

    • Support for Kriega OS-rack loops

    Countersunk holes, designed for Kriega rack loops, are strategically positioned. This will provide even more options for strapping various Kriega bags. 


    The reason for our higher price sits lies in the manufacturing process. In order to produce rack with angled spacer platforms, we start with 10 mm thick piece of aluminum, weighing approx. 2400 gr. And we remove approx. 1400 gr on CNC vertical machining center. This may seem like an overkill and it certainly isn't cost effective, but the final result justify it. 

    There are cheaper copies on the market, with some of these features, but not all of them. They will do the job for less money. But the Perun moto rack is the best and it provides more features.
