Fitting traditional style luggage to the new generation of sports bikes has become increasingly difficult. Underseat pipes and minimal bodywork dictate a new solution. Kriega  developed the US-10 tailpack in 2005. This year we have added the US-20. Both products fit to the seat-pad, with no extra bungee-cords . 100% waterproof construction on the main pack body and the packs can fold down when empty to store under the bike seat. The US-20 is also an effective way of adding storage to luggage racks and aluminium panniers.
