Designed to perfectly fit the latest lightweight enduro motorcycles with a tailored shape and specific mounting system. OS-BASE DIRTBIKE is an “over the seat” mounting system for attaching OS-6, OS-12, or OS-18 ADVENTURE PACK bags as soft side panniers, without the need for metal frames or racks.
This system offers an exceptionally durable and lightweight carrying solution with minimal modifications to the motorcycle bodywork. The mounting system allows flexible installation of one, two, or three bag configurations depending on the ride’s needs.
Fixed-length straps make installation quick and easy, while the tailored shape ensures a tight, secure fit and sufficient clearance from the exhaust. Installation takes less than a minute, removal only a few seconds.
2 × OS-DIRTBIKE RINGS
Attachable to the motorcycle’s main frame near the footrests. Designed to stay on the bike even when OS-BASE is not in use, providing a convenient front strap mounting point.
4 × OS-RACK LOOPS
Provides 4 hook-type mounting points for a separate OS-PACK or US-Drypack bag, or combined with additional loops in the OS-BASE system — allowing various 3-bag configurations. The rear 2 OS-RACK LOOPS provide a strong and secure rear strap attachment.
1 × SILICONE HEAT SHIELD
Provides secure protection from exhaust heat. It simply attaches to the muffler using the included hose clamps.
• Carrying capacity from 12 to 54 liters with central bag mounting option.
• Durable Hypalon® construction.
• Quick and easy installation/removal.

Original add-ons designed by the same engineers as your gear — guaranteed fit, zero compromises.
02 About the brand
We work only with brands we trust ourselves — original products, official warranty, and 20+ years of hands-on experience behind every recommendation.
The original difference
Excellent and professional place to buy gear and get service in summer and winter alike — motorcycles, accessories and servicing in summer, everything for skiing in winter. One of the best ski-boot fitting spots, with a knowledgeable specialist. Moto parts that aren't in stock are ordered in fast, and the on-site range is wide too.
A real pleasure working together! I especially appreciate that the team doesn't dodge problems — they fix mistakes fast. It's great to work with professionals you can rely on even in non-standard situations.
Great store, great service, great prices — all was perfect 👌🏽
Very good service. A clear, easy-to-use online store. After the purchase you get a confirmation and a tracking number. Delivery took a couple of days — and if you don't want to wait, you can pick the item up yourself.
Everything perfect, would happily order again 👍
Immediate shipping!!!
Everything fast and simple.
Immediate delivery to Poland. Everything was perfect. Thank you.
Very nice socks, bought as a gift.
Really fast delivery. Thank you.
Wide range of winter (skis, snowboards), summer (moto gear, hiking footwear) and electronics (drones, gimbals, mounts) products. They also offer drone pilot training.
On our way back from the North Cape we stopped by to replace the rear tyre on the motorcycle. Unfortunately they had no road tyres in stock and, it being Saturday, no mechanic either — but they went out of their way to find us a tyre shop that could help. Thank you very much!
