1. Kriega US-20 Drypack: Best Overall
The Kriega US-20 Drypack earns our top spot thanks to its rugged construction and proven performance. In our evaluation of owner feedback and spec sheets, this 20-liter bag consistently receives high marks for its 100% waterproof roll-top design and durable Hypalon/Cordura build. The four-point subframe harness attaches securely to the tail section, keeping the bag stable even at highway speeds. Riders report that it doesn’t shift or flap, which is critical for sportbike ergonomics.
However, the US-20 isn’t ideal for extended touring due to its moderate capacity. If you need to carry a full weekend’s gear, consider a larger model like the US-30 or US-40. Also, the mounting loops may not fit every tail shape; check compatibility with your bike before purchase. Despite these limitations, for day trips and commutes, this bag offers an excellent balance of security and waterproofing.
- 100% waterproof roll-top closure and welded seams keep gear dry
- Four-point subframe harness distributes load and stays stable at speed
- Made from Hypalon and Cordura for exceptional abrasion resistance
Pros: Fully waterproof without a cover; Secure mounting system works on most sportbikes
Cons: Limited capacity for longer trips
2. SW-MOTECH PRO Side Bag 30L: Best Large Capacity
The SW-MOTECH PRO Side Bag 30L is our top choice for riders who need maximum cargo space. Based on manufacturer specs and owner reviews, this 30-liter bag offers ample room for a change of clothes, tools, and more. The quick-release mounting system is convenient, though it works best when paired with SW-MOTECH’s SLC or STREET racks. The water-resistant inner liner provides decent protection, but the bag itself isn’t fully waterproof.
While the capacity is impressive, the bag’s size can affect aerodynamics on a sportbike; some riders report slight drag at high speeds. Also, if your bike lacks a compatible rack, installation becomes more complex. For riders who prioritize volume and don’t mind the extra bulk, this bag is a solid performer. However, those seeking a minimal profile should look elsewhere.
- Generous 30-liter capacity fits a weekend's gear
- Quick-release mounting system attaches to tail or side racks
- Includes water-resistant inner liner and reflective details
Pros: Large capacity for touring; Easy on/off with quick-release buckles
Cons: Requires a dedicated rack for optimal fit
3. Oxford Aqua T20 Tail Pack: Best Value
The Oxford Aqua T20 Tail Pack delivers reliable waterproofing at a competitive price point. Our research shows that owner feedback highlights its effective roll-top closure and welded seams, which keep contents dry in heavy rain. The adjustable straps allow for a decent fit on many sportbikes, though some riders note that the straps can be too short for larger tails. Reflective panels add a safety bonus for night riding.
Where this bag falls short is long-term durability; some users report seam wear after extended use. Also, the mounting system is less sturdy than premium options, so it may shift slightly on aggressive rides. For budget-conscious riders who need occasional waterproof storage, the Aqua T20 is a great choice. But if you ride daily in harsh conditions, investing in a higher-end bag may be wise.
- Waterproof roll-top construction with welded seams
- Adjustable mounting straps with quick-release buckles
- Reflective panels for increased visibility at night
Pros: Affordable waterproof option; Lightweight and easy to mount
Cons: Straps may not fit all tail sections securely
4. Vagabond Moto M-20 Tail Bag: Best Compact
The Vagabond Moto M-20 Tail Bag is designed for riders with limited tail space, such as on supersport bikes. In our evaluation of owner feedback, the compact shape and magnetic mount option (for steel tails) are praised for easy installation. The 600D polyester construction offers decent durability, and reflective piping improves low-light visibility. However, the bag is only water-resistant, not waterproof, so a rain cover is recommended for wet weather.
Some users note that the magnetic mount can lose grip on rough roads, and the strap version may not fit all tails securely. For riders who prioritize a low-profile bag for essentials like a jacket or lunch, this is a solid pick. But if you need full waterproofing or larger capacity, consider other options.
- Compact 20-liter design fits tight tails
- Magnetic mount available for steel tails (straps included for others)
- Reflective piping and durable 600D polyester
Pros: Great for small sportbikes; All-around mounting options
Cons: Not fully waterproof; Magnetic version only for steel tails
5. Nelson-Rigg Commuter Sport Tail Bag: Best for Commuting
The Nelson-Rigg Commuter Sport Tail Bag is tailored for daily commuters who need to carry a few items without bulk. Based on owner reviews, the 15-liter capacity fits a lunch, gloves, and a small laptop. It comes with both bungee cords and straps for mounting, though the bungee system can feel less stable than a dedicated harness. A rain cover is included to address the water-resistant shell.
Durability is average; some users report the zipper failing after a year of use. Also, the bag may shift during spirited riding due to the bungee attachment. For short trips and gentle commuting, this bag offers good value. But for aggressive riding or longer distances, a more secure mounting system is recommended.
- Compact 15-liter size ideal for daily essentials
- Multiple mounting options: bungee cords and adjustable straps
- Reflective strips and rain cover included
Pros: Convenient for daily use; Includes rain cover
Cons: Bungee mounting less secure than subframe harness
6. GIVI EA101B Tanklock Tail Bag: Most Secure Mounting
The GIVI EA101B Tail Bag uses the Tanklock system, originally designed for tank bags, to provide an exceptionally secure fit on compatible sportbikes. In our evaluation, this bag is praised for its stability at high speeds, but the 10-liter capacity is limiting. It can only hold a few small items like a phone, wallet, and keys. The water-resistant shell is adequate for light rain, but not for downpours.
A major drawback is the requirement for a GIVI Tanklock ring (sold separately) that must be installed on the fuel cap or tail area. This adds cost and complexity. For riders who prioritize a rock-solid mount and only need minimal storage, this is a niche option. Most sportbike riders will find the capacity too small for practical use.
- Proprietary Tanklock mounting for secure attachment
- Compact 10-liter size for minimal interference
- Reflective insert and water-resistant material
Pros: Extremely secure mount; Very compact and aerodynamic
Cons: Very small capacity; Requires GIVI Tanklock ring (sold separately)
7. Viking Bags Medium Tail Bag: Budget Pick
The Viking Bags Medium Tail Bag is the most affordable option in our guide, but it comes with significant compromises. In our research, owner feedback indicates that the faux leather material looks good but offers minimal weather protection; water can seep through seams. The universal strap mounting is basic and often fails to keep the bag secure on sportbikes, with reports of shifting or even flying off at highway speeds.
Durability is a concern; the stitching and zippers aren’t built to withstand regular use. This bag may appeal to riders on a tight budget or those who only need occasional, low-speed storage. For anyone riding a sportbike at speed or in wet conditions, we strongly advise against this pick. Invest a bit more for a safer, more reliable option.
- Classic faux leather look for cruiser-style sportbikes
- 15-liter capacity for small loads
- Universal strap mounting system
Pros: Inexpensive option; Stylish appearance
Cons: Not waterproof; Poor stability at high speeds
Frequently Asked Questions
How do I choose the right size tail bag for my sportbike?
Consider your typical cargo needs. For daily commuting, a 10-15 liter bag is often sufficient. For weekend trips, look for 20-30 liter options. Ensure the bag doesn’t interfere with the passenger seat or tail section. Measure your tail area and compare with bag dimensions.
Are tail bags waterproof?
Not all are fully waterproof. Look for roll-top closures and welded seams for true waterproofing. Many bags are water-resistant and include a rain cover. Check the product specifications and owner reviews for real-world wet weather performance.
Will a tail bag affect my sportbike's handling?
A properly mounted tail bag should have minimal effect on handling. However, large or heavy bags can shift weight and affect aerodynamics at high speeds. Secure mounting systems like subframe harnesses or dedicated racks help maintain stability.
Can I install a tail bag without a rack?
Yes, many tail bags use straps, bungees, or magnetic mounts that attach directly to the tail section. However, the security varies. For aggressive riding, a bag with a subframe harness or a rack-mounted system is recommended.
How do I clean and maintain my tail bag?
Most bags can be wiped clean with mild soap and water. Avoid harsh chemicals. For waterproof bags, periodically check seams and zippers for wear. Store the bag dry to prevent mold. Follow the manufacturer’s care instructions.
Our Verdict
After researching, comparing, and evaluating the best tail bags for sportbikes, we recommend the Kriega US-20 Drypack as the top pick for its exceptional waterproofing, durable build, and secure mounting. For riders needing more capacity, the SW-MOTECH PRO Side Bag 30L is a strong runner-up, offering generous space and quick-release convenience.
