30-litre capacity (US-20 + US-10 combo.) 100% waterproof tailpacks. Innovative design solution which can fit directly to the seat-pad or to the tank (see TANK option below). The US-20 also comes equipped with removable shoulder and waist straps. It can be carried courier style, on or off the bike. The US-10 can fit on either side or on top of the US-20. Once connected together they can be removed as one single luggage 'block'. Save money by buying the US-20 and 10 together.
The US-30 tailpack is designed to fit most race-rep style seat pads (attachment straps included). The pack/s are easily attached/removed by 4 x quick-release buckles. No extra bungees or rain covers are required(see US-20 fitting page). The US-10 can attach to either side or on top of the US-20. The UScombo30 tailpack is designed to fit with custom 6061-T6 alloy hooks (supplied). Both the US-20 and US-10 packs can either independently attach to the bike or be attached together to provide 30-litres of storage. Once connected the two packs can be removed from the bike as one luggage 'block'. NB - US-packs can be mounted inline or across the seat.
The US-packs have never been easier or quicker to take on and off, with no loose straps left on the bike. The ultra secure subframe fitting is particularly suitable for bolt on seat pads and traditional one-piece seats (4 x web loops attach to the subframe and exit at the seat edge). Attach the 4 x alloy hooks to the loops and compress the pack down with the quick release adjusters. Secure the loose strap ends with the web tidy components and you're ready to go.
I bought this as a 'starter' kit to sit on the back of my Triumph Street Triple R as a waterproof means to carry my gear. I've had a Kriega R30 for a number of years and, while it's a stellar pack, it's far too big for my general requirements. The US30 kit is perfect in that I can fit the US20 inside the US10 along with my rain gear and some other general items, and it gives me the chance to expand my carry capacity, should I need it.
Fitting the mounting points did take some work, and wasn't straight forward, as I had to frequently unscrew and reattach panels on the bike to make sure fitment was right. Even now I think it sits a little too far forward for my liking, so I'll revisit that soon.
While the packs are on the bike they look good, with the compression straps helping to keep the look of the bike sleek and curvy. They don't look out of place like some fixed rack packs. And, when removed, the only sign of the US Packs are 4 small webbing tabs poking out from under the seat.
The US Packs don't have any ability to segregate items, so if you carry a lot of smaller items (pens, usb sticks, cables, leads, etc) it would be wise to invest in pencil cases or small soft bags to keep things itemised. It will also help you when packing for longer rides where, if you need a pen and a notebook, you know you'll find it in your red pencil case, and your USB memory sticks are with your camera/phone leads in your blue pencil case.
Anyway, it's a lot of money to spend on storage, but the quality (and the style that comes with it) makes it worth while.
