A tank bag is a good way to lug your stuff on the bike. It keeps the weight more central than a tail pack and – unlike a rucksack – it means you don’t have to worry about carrying anything on your person.
Some people choose a tank bag for the safety aspect, others because they just don’t like having anything on their back.
There are two common types of tank bag and a third which is less common but growing in popularity with the rise in Adventure motorcycle sales.
The most common is the magnetic tank bag. There are magnets in the base and this ‘sticks’ the tankbag to your tank. This worked with almost every bike a decade ago but now more bikes have non-metallic tanks, quite a few are plastic or have a plastic shroud. If you have a magnetic tank, these tank bags are universal.
The second type uses a clamp. You set it up by bolting a clip or ring around your filler cap and the tank bag then connects to this ring. The majority of these tank bags are universal but if you have more than one bike, you’ll need to buy a clamp for each bike you want to use the tank bag on.
The third type uses a harness or straps which the tank bag clips on to. These types of tank bags are more popular with Adventure bikes but there make universal types with adjustable straps which you can tweak to fit any tank.
There’s a huge price difference when it comes to choosing a tank bag. It essentially boils down to the size of the tank bag, the attachment type, the features and the build quality.
If you just want something to carry a few bits and pieces on a sunny day, a cheap tankbag will do the job. It won’t be waterproof and it probably won’t last a lifetime but it’ll get the job done.
If you’re touring and you need a large tank bag that’s fully waterproof, you’re going to be looking at something that’s over £100.
Although the price has been a factor in our considerations, we’ve recommended the tank bags that we think are the best available right now – we haven’t just gone for the most expensive.
If our picks don’t work for you in terms of budgets, brands or features, then refer to our shortlist where you’re sure to find a great option.
If you have a metal tank then a magnetic tank bag is a great option. Easy to mount and remove but stable and secure. They usually come with a strap to wrap around the headstock for added security.
This 6-litre tank bag has a handy clear window for your phone and detachable shoulder strap for easy carrying off your bike. Compatible with metallic and non-metallic tanks.
Suitable for magnetic and non-magnetic tanks, this 25-litre Easy-T by Givi features a clear map pocket, rain cover and extractable shoulder straps for a handy backpack off your bike. It won a RiDE Best Buy too.
You mount a ring or clamp to your bike’s fuel cap and the tankbag then clips into this ring. It’s sturdy and secure but you’ll need additional tank rings if you want to move the tankbag between bikes.
This compact 4-litre bag features an inner case for sunglasses, clear window for your smartphone and a detachable shoulder strap which complements its carry handle.
A 30-litre expandable tank bag with a practical electrical port and pocket for your device. The clear pocket is ideal for maps or smartphones and is complete with a sun shield.
You set up the harness on the bike (usually looping around the headstock and then under the tank or under the seat, secured to the subframe). The tankbag then attaches to the harness, either with a zip or a clip or Velcro. They’re popular with riders of Adventure and Enduro bikes.
Suitable for bikes with narrow, sloping tanks, the Motech ION is a massive 13-litre capacity (expandable to 22L) tank bag with snap buckles for easy lift-up refuelling. The Motech ION features a cable port, reflective detailing and carrying handle.

These are the features that we think every good motorcycle tankbag should have.
Shoulder strap: Tank bags with some form of shoulder straps are great for doubling up as a rucksack when you’re off your bike.
Magnets/straps: If you have a metallic tank, choosing a tank bag with strong magnets with back-up straps for attaching to your bike is a must.
Clear pocket: Great for placing your smartphone or a map in and keeping an eye on your route.
Stiffeners: You’re not always going to fill your tank bag to full capacity, stiffeners help support the shape of the bag and protect your items from becoming squashed.
Carry handles: Like shoulder straps, this is a helpful feature when you need to cart your stuff around.
Rain covers: Let’s face it, the weather is unpredictable so having a tank bag with a rain cover or some form of waterproofing is handy, even if the tankbag claims to be waterproof on its own.
Headstock strap: This helps keep the tank bag secure and reduce the risk of it falling off your bike.
Expandable storage space: Whether you choose a large or small tank bag, the best ones have expandable storage space (usually in the form of extra zips) then when you don’t need room for the kitchen sink, you can reduce the area of the bag making it less bulky.
Secure closures: Being out in the open air, travelling along at high speed, you need good strong zip closures. Make sure they are easy enough to open with your gloves on to save time.
Quick access pocket: A side pocket gives you access to change, your wallet, or other essentials, meaning you don't risk dumping the contents of your tankbag at the toll booth when you're reaching for your credit card.
A couple of times a year both Aldi and Lidl offer a range of motorcycle clothing accessories and luggage. They publish them in their ‘Special Buys’ section.
Most of it is actually pretty good and it’s cheap too.
Their luggage is pretty decent. It’s a bit heavier and clunkier than the more pricey rivals but it does the business. They only sell magnetic tank bags but they come in at around £30 for a large one which is good value for money.
If you just want a tank bag to carry the essentials, like your house keys, wallet and phone then a small tank bag will do the job nicely.
Most of them are magnetic and some have a backup strap that you feed around the top yoke.
With a clear top pocket, they’re also a handy way of being able to run a sat nav app on your phone and be able to glance down occasionally, to check you’re on the right path.
Most ‘plastic’ tanks are usually a metal tank with a plastic shroud. The majority of tanks are metallic at the front. Check first before you buy a mini magnetic tank bag because if it’s only secured around the top yoke, it’ll spend all of its time levitating over the tank which is funny at first but also properly dangerous.
Don't place a magnetic tank bag on the floor with the magnets down - it will pick up all sorts of crap which will then scratch your tank.
Check to see if your bike's manufacturers produced official luggage. You might find a neater, better-fitting option in their official accessories.
Always strap the retainer around the headstock. Make sure it doesn't restrict bar movement but ensure it's tight enough that it'll stop the tankbag from moving move than a couple of inches.
Don't drag a magnetic bag from your tank or you may scratch it.
If you use a magnetic tank bag, be careful that the magnets don't mess with your phone, USB stick, camera etc. Place these items higher up in the bag.
Are motorcycle tankbags waterproof?
Every one is different. Some claim to be waterproof but you still might want to wrap everything in a bin liner if it’s important it doesn’t get wet, rather than trust the claims. Others aren’t waterproof but will come with a cover that you can put over the top of the tank bag. This is a bit of a faff and means the map pocket will be covered over too. Far better to get a tankbag that’s billed as waterproof if you’re going to be riding in all conditions.
