The R 303 is the largest of the GKA universal boxes at 96 litres, and it comes with a backrest in the set. Those two facts together are what separate it from the rest of the line: more room, and a passenger who has something to lean on. Sealing is the D-profile rubber gasket used across the range — a hollow section that compresses along the whole lid, rather than a flat strip that only touches where the catches pull tight. The shell is first-grade imported high-density polyethylene. Mounting is the universal adjustable U-bracket set, so it fits most machines rather than one. Two red reflectors are fitted at the rear. Empty weight is 10.33 kg — the price of the extra volume and the backrest. SKU: R-303 Riding two-up over distance is where this one makes sense. A passenger without a backrest holds on for the whole trip; with one they can sit properly, and 96 litres carries what two people need for the day. Solo it is simply the biggest of the universal boxes — expedition kit, tools and food in one sealed, locked case. Universal, through the adjustable U-bracket set. Confirmed brands include Stels, Hisun, CFMOTO, Cectek, Yamaha, Honda, BRP, Suzuki, Polaris, Kawasaki and Kymco. If your rack is small, the R 302 uses the same shell with a narrowed base that fits more racks, at the cost of some internal volume. For less weight without a backrest, the R 301 holds 80 litres at 8.25 kg.GKA R 303 — Rear ATV Box with Backrest, 96 Litres
