8 Best Motorcycle Tail Bags to Buy in 2025

If you’re chasing maximum cargo capacity without sacrificing stability, the Rhinowalk 60L Tail Bag is a game-changer for long-haul riders and touring enthusiasts. Its dual expansion zippers push storage from 40L to a cavernous 60L—rare in the tail bag category—while the reinforced steel wire frame and PE sheet backing keep the bag rigid and balanced, even at highway speeds. This isn’t just a soft sack that flops around; it’s a structured travel solution that resists shifting, making it ideal for riders who carry gear for weekends or cross-state trips.

In real-world testing, the bag excels on paved highways and mild backroads, securely holding helmets, jackets, and even camp supplies. The 6000mm waterproof rating means it laughs off downpours, and the included rain cover adds an extra layer of confidence. Mounting is straightforward with four large 2.5cm straps and sissy bar compatibility, though fitting on smaller bikes or those without rear racks can be tricky. While the weight (4.6 lbs) is noticeable compared to compact models, the payoff in load-bearing performance and weather resistance justifies it for serious riders.

Compared to the KEMIMOTO and MOSISO models, this Rhinowalk bag is in a different league—built for endurance, not errands. It competes more directly with premium touring luggage systems, offering modularity and durability at a mid-tier price. Ideal for adventure riders, dual-sport travelers, and anyone who refuses to downsize their gear. It delivers more volume and structural integrity than the KEMIMOTO, though with less portability as a backpack.

The KEMIMOTO 22L–34L Tail Bag strikes a perfect balance between versatility and value, making it the smart choice for daily commuters and weekend riders who want flexibility without overspending. Its standout feature is the dual-use design: securely mounted on your bike, it transforms effortlessly into a backpack or shoulder bag, thanks to hidden straps and a padded carry system. The 1680D leather fiber exterior delivers impressive abrasion resistance, while the full rain cover ensures your gear stays dry even in sustained storms.

On the road, this bag performs reliably across city streets and highway runs. The 34L max capacity comfortably fits a full-face helmet, gloves, and a jacket—ideal for riders who need to stash gear at work or during errands. Installation uses six adjustable straps, offering a snug fit on most standard seats, though it struggles on deeply contoured or cruiser-style saddles. While not as rigid as framed bags, it maintains shape well and resists flapping at speed. The side zip pocket is a small but meaningful touch, giving quick access to keys or phone.

Against the Nelson Rigg CL-1060-S2, the KEMIMOTO offers broader functionality at a fraction of the cost, trading premium materials for practicality. It’s not as sleek or durable long-term, but for riders who value portability and multi-role use, it’s a standout. It beats the Socpuro in capacity and build, while offering better backpack ergonomics than most in its class.

The Socpuro Tail Bag is the budget warrior of the bunch—proof that affordable doesn’t mean inadequate. Priced under $20, it delivers essential waterproofing with PU leather construction that handles light rain and road spray, making it perfect for fair-weather riders or short commutes. Its zipper-and-buckle design allows for ultra-fast removal, so you can grab your bag and go without wrestling with straps. The inclusion of a shoulder strap and rubber handle adds surprising versatility for its size and price.

In real-world use, it’s best suited for carrying small essentials: phone, wallet, snacks, gloves, or a light jacket. The 12″x10.4″x8″ interior won’t fit a full helmet, but it’s spacious enough for daily riders who don’t need heavy storage. Mounting is simple with two wraparound straps and four buckles, though the fit can loosen on bumpy roads if not tightened properly. While it lacks reflective detailing beyond a small logo, its anti-slip bottom helps prevent shifting during acceleration or braking.

Stacked against the MOSISO and ViaTerra, the Socpuro wins on pure affordability and ease of use. It doesn’t match the waterproof confidence of the ViaTerra or the sleekness of the Nelson Rigg, but for a first-time rider or someone needing a no-frills, removable bag, it’s a steal. It offers more removable convenience than fixed saddlebags at this price, though with less weather protection than pricier models.

When absolute waterproofing is non-negotiable, the ViaTerra 6L Tail Bag stands alone—its triple-layer fabric and ultrasonic seam welding eliminate weak points, making it the only model in this lineup that needs no rain cover or liner. This is mission-critical gear for riders in rainy climates or off-road conditions where electronics or documents must stay bone-dry. The waterproof zipper operates smoothly, and the EBC external net lets you stash gloves or a rain suit for quick access without opening the main compartment.

Despite its small 6L size, the interior is thoughtfully organized with a mesh zip pocket and internal separator, keeping small items from turning into a jumbled mess. It mounts securely via a zero-displacement buckle system, eliminating wobble even on rough trails or gravel roads. The non-slip bottom grips surfaces tenaciously, and the removable shoulder strap makes it easy to carry into cafes or gas stations. It’s not for gear haulers—but for minimalist, weather-proof storage, it’s unmatched.

Compared to the MOSISO and Socpuro, the ViaTerra is in a different category: pro-grade protection over volume. It’s smaller than most, but its engineering and sealing tech outclass everything else here. Ideal for adventure riders, commuters with sensitive gear, or anyone who’s had a bag fail in the rain. It offers better waterproof integrity than the Rhinowalk, even though it carries far less.

The Rhinowalk 30L Modular Tail Bag redefines flexibility with its true modular design, allowing riders to mix, match, and scale storage based on trip needs—whether you need a single 10L pouch or a full 30L system. Each bag features interlocking buckles and hooks, enabling 2-in-1, 3-in-1, or even 4-in-1 configurations, making it ideal for custom setups on racks, sissy bars, or fuel tanks. The full waterproof inner bag with detachable zipper ensures contents stay dry, while the anti-slip mesh exterior lets you hang damp gear like rain suits or gloves.

In practice, this system excels for riders who customize their loadout—adventure tourers, camping riders, or those with irregular cargo. The 30L version is lightweight (1.15kg) yet robust, with solid brand buckles and reinforced webbing that endure repeated use. You can use individual bags as tank pouches, panniers, or shoulder bags, maximizing utility. However, the modular nature requires more setup time, and keeping multiple pieces organized can be a challenge for casual riders.

Versus the Nelson Rigg or KEMIMOTO, this Rhinowalk model trades simplicity for customization and multi-role potential. It’s not as plug-and-play, but for DIY-minded riders, it’s a game-changer. It offers greater adaptability and mounting options than any other bag here, though with a steeper learning curve.

If your top priority is secure helmet storage, the CamGo 20L–28L Tail Bag is purpose-built to deliver, with an expanded main compartment that easily swallows a full-face helmet, gloves, and goggles. The PVC-oxford hybrid material offers excellent water and stain resistance, ensuring your gear stays clean and dry even after a muddy ride. Its dual-use design—with removable shoulder straps and a top handle—makes it easy to carry off the bike, functioning as a backpack, shoulder bag, or hand carry with minimal effort.

On the road, the bag stays put thanks to multiple mounting straps and a reflective stripe that enhances night visibility. The interior includes a zippered top pocket for small items like keys or wallet, while the main space is cavernous when expanded. It fits most mid-to-large bikes but can look oversized on smaller cruisers or sport bikes. While the waterproofing is strong, it lacks a separate rain cover, so extended monsoon-level rain might test its seams.

Compared to the KEMIMOTO, the CamGo is more focused on helmet storage, with a slightly stiffer build and better shape retention. It’s not as versatile as the Rhinowalk modular system, but for riders who routinely remove and carry their helmet, it’s the most practical choice. It offers better helmet fit and protection than any other model in this lineup.

The MOSISO 10L Tail Bag is the lightweight champion, tipping the scales at under 2 lbs and designed for riders who want minimalist, no-drag storage without sacrificing function. Its waterproof PU leather construction shrugs off light rain and road grime, while the anti-slip bottom keeps it planted during spirited rides. The adjustable shoulder strap (28–50 inch) ensures a comfortable carry when removed, and the top rubber handle makes grab-and-go effortless—perfect for quick stops or urban errands.

In daily use, it’s ideal for carrying essentials: phone, wallet, tools, power bank, or a small jacket. The 10L capacity is modest but well-utilized, with a single main compartment that’s easy to pack and access. Mounting is simple with four buckles and two seat straps, though the fit can loosen on larger seats if not tightened fully. It’s not built for long trips or heavy loads, but for lightweight, reliable utility, it’s spot-on.

Against the ViaTerra and Socpuro, the MOSISO strikes a sweet spot between price, weight, and usability. It’s lighter than the ViaTerra and more durable than the Socpuro, though not as waterproof. Best for commuters, scooter riders, or minimalists who want a clean, functional bag that disappears when not needed. It offers better ergonomics and adjustability than the Socpuro, though with less weather protection than the ViaTerra.
