How to Choose a Motorcycle Tail Bag

Evaluating Tail Bag Options
A motorcycle tail bag typically has a streamlined shape that aligns well with the contours of your bike. Many are made from weather-resistant materials, ensuring your belongings remain dry. Features can include reflective strips for visibility, external pockets for easy access, and adjustable straps for secure attachment. Some even have expandable compartments or hard-shell designs for added protection.
When choosing a tail bag, prioritize functionality over aesthetics. Opt for the most versatile option that meets your storage needs while being compatible with your bike.
Top Features to Consider When Choosing a Motorcycle Tail Bag
1. Capacity
- Size: Choose based on trip length and storage needs.
- Expandable Options: Some bags offer expandable compartments for flexibility.
- Fit: Ensure the bag’s size matches your bike’s tail section.
2. Mounting System
- Straps: Ensure they are durable, adjustable, and easy to use.
- Bungee Cords: Provide flexibility but may be less secure on rough terrain.
- Dedicated Mounting Points: Some bags have tailored mounting systems.
- Quick-Release: Allows for easy removal.
3. Materials and Durability
- Weather Resistance: Waterproof or water-resistant materials are ideal.
- Construction Quality: Look for double-stitched seams and strong zippers.
- Rigid vs. Soft: Rigid bags retain shape but may be heavier; soft bags are lighter and more flexible.
4. Compatibility with Your Bike
- Tail Shape: Ensure the bag fits well on your tail section.
- Exhaust Clearance: Prevent heat damage by checking placement.
- Passenger Use: Confirm space for a pillion rider if needed.
Tail Bag Drawbacks
While tail bags are generally known for being extremely convenient, there are some potential drawbacks that you should keep in mind.
One of the most common issues associated with a tail bag is limited storage capacity. Because they are often small and light, you may have to spend extra time finding options that will fit all of your most crucial belongings. Be sure to check if any bags you are considering are expandable, as this can significantly increase your storage capabilities. While tail bags are generally known for being extremely convenient, there are some potential drawbacks that you should keep in mind.
Another common issue is not with the bag itself, but rather how you mount it. Not all tail bags fit every motorcycle, so if your bike has a smaller or unusual tail section, you might run into compatibility issues. Additionally, an improperly mounted bag can shift or even come loose during a ride, particularly on rough terrain.
Take the time to find an option that fits your bike, and carefully follow the mounting instructions to ensure everything stays securely in place. This is especially important if you plan to ride two-up, as the placement of the bag may interfere with your passenger’s seating. Additionally, a heavily loaded tail bag can affect your bike’s balance and handling.
Finally, accessibility can be a concern. Unlike tank bags or top boxes, tail bags are not easily accessible without getting off the bike. While you shouldn’t be reaching into your bag while riding, it can become frustrating to repeatedly dismount to retrieve small items—especially if your tail bag requires unfastening multiple straps.
