The R 305 was drawn around BRP racks and then found to fit most other machines as well. Its proportions are what set it apart from the rest of the GKA line: at 1122 mm long and only 380 mm tall, it is the long, low box in the range. That shape matters more than the litre count suggests. Eighty litres spread over a long, shallow footprint keeps the centre of gravity down and puts nothing high behind the rider — which on a machine ridden hard is worth more than the same volume stacked tall. The lid carries a rubber sealant against water, metal locks with keys hold it shut, and the universal adjustable U-bracket set does the mounting. Empty weight is 9.1 kg. SKU: R-305 Riders who care how the machine handles loaded will notice the difference. A low box changes the balance less, and on fast or technical ground that is the point of choosing this one over a taller 80-litre case. The long footprint also suits awkward loads — a folded saw, poles, anything that will not go into a short deep box. Developed for BRP Can-Am and compatible with most other ATVs through the adjustable U-bracket set. The same box is listed for Can-Am owners as the BRP Cargo Box R 305, with the full Can-Am fitment list. For a taller box with a backrest, see the R 303.GKA R 305 — Long, Low Rear ATV Box, 80 Litres
