Saddlebags vs Tour Packs vs Sissy Bar Bags: Which Motorcycle Luggage Do You Actually Need?

A rigid, box style storage container mounted behind the rider (or behind a passenger) on a dedicated rack or fender mount is what most people mean by a tour pack, also called a top case. Unlike saddlebags, it sits higher and further back, which gives it more usable volume for bulky items such as helmets, rain suits, and camping gear, at the cost of adding more weight higher and further from the bike's center of gravity. Viking Bags' tour pack collection is organized by bike make and model for this reason, since fender and rack mounting points differ by bike.

You need a tour pack if you regularly ride two up, take multi day trips where saddlebags alone aren't enough, or want a single lockable, weather resistant space for bulky gear. If you mostly ride solo and pack light, saddlebags alone are usually enough, and skipping the tour pack keeps the bike lighter and easier to handle at low speed. Most tour packs are built from fiberglass with a gasketed lid, which holds up to road vibration and sheds water better than a soft bag, though a gasket in worn or poor condition won't perform the same way, so it's worth checking that seal periodically rather than assuming it. Riders who carry a passenger often add a passenger backrest pad to the front of the tour pack, which does double duty as passenger comfort and a mounting point for the trunk itself.

A soft sided bag that straps directly to a motorcycle's sissy bar, the raised backrest frame mounted behind the seat, is a different setup from a saddlebag rather than a smaller version of one. It sits on the centerline of the bike instead of straddling the rear wheel, so it doesn't require the wheel clearance or frame brackets that saddlebags need, which makes a sissy bar bag a common choice for bobbers and stripped down cruisers that don't have room for saddlebags. Many install in minutes on a folding sissy bar, without any drilling.

The tradeoff is capacity and stability. A sissy bar bag typically holds less than a full saddlebag setup, and because it's mounted higher and further back, an overloaded sissy bar bag will affect handling more noticeably than saddlebags of the same weight. Riders who want a smaller, lower profile alternative sometimes choose a swingarm bag instead, which mounts directly to the swingarm and holds a couple of liters for a wallet, tool kit, or spare key rather than a full change of clothes.

A soft sided bag that straps directly to the rear seat or subframe, rather than mounting on the sides of the bike or on a sissy bar, is the most minimalist and widely compatible option on this list. It works on nearly any bike, including sport bikes and standards that don't have saddlebag mounts or a sissy bar at all. Check the specific tail bag listing for whether a rain cover is included, since this varies by model rather than being standard across every bag.A tail bag makes sense for quick weekend trips, riders who want to add and remove luggage in seconds without any hardware, or as a second bag added on top of saddlebags for extra capacity on longer rides. It's not the right choice as your only luggage for a multi day trip, since capacity tops out lower than saddlebags or a tour pack.

Worn on the rider's body rather than mounted to the bike, a riding backpack is the only luggage type on this list that travels with the rider off the bike as well as on it. That's the main advantage: no mounting hardware, no bike-specific fitment questions, and it comes into the gas station or hotel with you automatically. Many riding backpacks are also built to strap onto a sissy bar or luggage rack when you don't want to wear them, turning the same bag into rack-mounted storage for the stretch of highway where you'd rather not carry the weight on your shoulders.

The tradeoff is rider comfort and safety. A loaded backpack shifts the rider's center of gravity, can cause back strain on long rides, and adds fatigue that saddlebags. Which carry the load on the bike rather than the body - don't. Most experienced long-distance riders use a backpack for a laptop, wallet, and phone, and rely on saddlebags or a tail bag for everything else. On backpacks built for ADV riding specifically, a chest or waist harness is common, since it keeps the bag from swinging around while standing on the pegs over rough terrain.

Hard or soft sided cases mounted on a dedicated luggage rack, built for adventure and dual sport motorcycles, are what most riders mean by adventure touring side cases or ADV panniers. They're built for a different job than cruiser saddlebags. Cruiser saddlebags are optimized for road use and a specific factory look, while ADV panniers are built to survive drops, water crossings, and off road vibration, and they usually mount higher and further out to clear long travel suspension. A key-lockable latch and a rubber gasket around the lid are what actually keep water out on a case, more than the shell material itself.

The two main types are aluminum cases, which are the most crash and abrasion resistant but add the most weight, and polymer/composite cases, which are lighter and often cheaper but can crack under a hard impact rather than dent. Riders doing mostly pavement touring on an ADV bike often lean toward polymer cases for the weight savings; riders doing serious off road or overland travel tend to prefer aluminum for its durability. Owners of bikes like the Harley-Davidson Pan America or the BMW GS series can generally start with side racks built for their specific model, since a rack that isn't matched to the bike's subframe and exhaust routing won't line up correctly. For riders who want top case capacity in addition to side cases, the broader ADV touring luggage lineup covers tank bags, tail bags, and top cases built for the same bikes.
