Waterproof Motorcycle Tail Bags: A Guide to Choosing the Right One

Whether for the daily commute in driving rain or the road trip of a lifetime across Europe, luggage is a real challenge for any rider. The winning formula is threefold: keep your gear dry, transport it securely, and never compromise your bike's handling. The wrong equipment can quickly turn a dream adventure into a logistical nightmare.

This guide has one mission: to give you all the keys to finding the waterproof motorcycle tail bag that perfectly suits your needs. We'll scrutinise the technical features that truly matter and present a selection of proven products, cutting through the marketing hype.

How to Choose Your Waterproof Motorcycle Tail Bag?

Before diving into our selection, let's review the three fundamental criteria that separate a good motorcycle travel bag from a great one.

1. Capacity: Assessing Your Real Needs

Volume, expressed in litres, is the logical starting point for your decision.

  • For daily commuting or day trips: A volume of 30 to 40 litres is generally sufficient to carry a laptop, rain gear, a lock, and a few personal items.
  • For weekends or short trips: Aim for a capacity of 50 to 70 litres. This allows you to pack a change of clothes, a toiletry bag, and small items without playing Tetris.
  • For long journeys (road trips): A large-capacity motorcycle tail bag of over 70 litres is essential. It can accommodate camping gear, tools, and enough belongings for one or more weeks. It's a cornerstone of your motorcycle road trip gear.

2. Material and Waterproofing: The Key to Durability

Waterproofing is the non-negotiable criterion. Most high-performance bags are made from PVC motorcycle luggage (polyvinyl chloride) or coated Tarpaulin canvas. These materials are renowned for their toughness and complete impermeability.

The closure system is just as crucial. The roll-top closure, often called a "roll-top", remains the most reliable solution. The principle is simple: you roll the bag's opening over on itself several times before clipping it shut. The result is an infallible barrier against water and dust. It's a proven technology from the worlds of sailing and adventure, guaranteeing your gear will stay dry, even in a downpour.

3. Mounting and Security: Details That Matter

A universal motorcycle bag is ideal, capable of fitting most bikes (roadsters, adventure bikes, cruisers) without needing a specific rack. Check that the bag comes with a set of sturdy straps and multiple anchor points. Systems with quick-release straps are a game-changer for daily use, making installation and removal much easier.

On the security front, the presence of reflective elements is an undeniable plus. They increase your visibility to other road users in low light or at night. It's a detail that can make all the difference.

Frequently Asked Questions (FAQ)

How do I properly secure my motorcycle tail bag?

Stability is paramount for your safety. Use the provided straps to firmly secure the bag to the frame, luggage rack, or passenger grab rails. Don't hesitate to cross the straps for a better hold. Ensure no straps are dangling where they could get caught in the wheel or chain. Before every ride, a quick check of the tension and for any slack is essential.

Is a PVC bag with a roll-top closure truly waterproof?

Yes, it's the most reliable configuration on the market. PVC canvas is inherently waterproof. The roll-top closure, when done correctly (at least three rolls before clipping), creates a seal that blocks any water ingress, even during heavy downpours or from spray. You should simply avoid total and prolonged submersion of the bag.

What capacity should I choose for a one-week road trip?

For a one-week trip, a volume of 60 to 70 litres, like the 66L model, is an excellent compromise. This gives you enough space for your clothes, a pair of shoes, a toiletry bag, and a few extras, without overloading the motorcycle. If you plan on camping, the 86L model will be more suitable for carrying the additional gear.
