A larger version of the popular OS-BASE that is specifically designed to fit the KTM 790 / 890 ADVENTURE & ADVENTURE R. The OS-BASE is an 'over the seat harness' which allows OS-6, OS-12 or OS-18 ADVENTURE PACKS to be mounted as soft panniers. No heavy metal frames are required, this system provides a super-tough, lightweight carrying solution for the KTM 790 or 890 with no permanent bodywork alterations to the bike. The modular design enables you to modify your luggage set-up to suit your ride - from a days single track to longer moto-camping adventure trips. The KTM RACK LOOPS included, attach to the bikes baggage carrier/ rear rack and provide 4 optional hook-on points. Used in conjunction with the additional loops on the OS-BASE they provide various mounting pointsfor a 3 or more bag set-up, or can be used to mount anOS-PACK as a stand alone tail pack without the OS-BASE. The set length straps make mounting a breeze and the purpose designed main body shape provides a tight, secure fit with plenty of distance from the exhaust. It takes less than a minute to mount the system to the bike and just seconds to remove it. Fits: KTM 790 ADVENTURE 2019-2020 790 ADVENTURE R 2019-2020
