The best ring mounted tank bags - carry more with MCN's used and reviewed favourites

When it comes to riding motorbikes, there is often a need to carry more with us than we can fit into our pockets, especially if you are a sportsbike rider in full leathers. This where motorcycle luggage comes in with various options available such as rucksacks, leg bags, tail bags, panniers or waist bags. Which you choose, will probably depend on your choice of bike, personal taste and preference. A popular option is to use a tank bag.

What is a tank bag and what to consider?

A tank bag is exactly what it sounds like, it’s a bag that fits onto the bike’s fuel tank. The appeal with this type of luggage is that it is right in front of you, providing a couple of benefits; all of your items are easily accessed while on the bike, ideal for things like wallets or passes; and secondly, especially relevant to sportsbike riders, they provide a pad to rest against to help to keep the weight off of your wrists when leant over on longer journeys.

They tend to be fitted either using magnetic panels on the bottom of the bag or by a fuel cap ring. Magnetic attachment is quick and easy but may not be as secure if you want to carry a larger load and may result in scratching the finish and pant on the fuel tank. Also bear in mind that a magnetic variant won’t work if you don’t have a metal tank, some later motorcycle models have a plastic exterior to save on cost and weight, therefore a magnetic tank bag will not be able to stick on to this type of fuel tank.

The ring attachment systems are more secure but can be a little more fiddly and leave behind a rigid plastic ring when the bag is removed. It also requires some fitting, so you will need to be handy with a screwdriver or socket set. The attachment ring is often not included with the bag so this will mean an additional cost is involved.

Which is better? That really depends on your personal use; a magnetic option could be perfect if you rarely require luggage and perhaps ride a sportsbike, this way you don’t ruin the look of your bike with a plastic ring mount when its not in use. However if you regularly require the ability to carry additional luggage when you ride and want to carry heavier items for long distances, then a ring mounted bag could be ideal for you. Especially if you aren’t too worried about the ring being left there when you remove your luggage from the bike.

The best tank ting bags we’ve tested

Price: £117.67 (was £138.98)
Tried and tested by Alison Silcox for one year

"As my 5’4” tall Grandad always said, all good things come in small packages, and that’s definitely the case with the Pro Daypack Tank Bag from SW Motech. Made from heavy duty nylon, it will hold between five and eight litres of gear. In reality, that’s my sandwiches, phone, wallet, keys, all the usual stuff you need for a quick ride out and for journeys further afield, it’s great for passports or documents."

"A tank mount is required, which is an easy fit, replace the screws in the top of the fuel cap with the ones in the kit and the mount sits proud of the tank. The bag then fits in place and to remove, just pull the red tabs to un-hook the securing mechanism. A raincover is included but I managed to lose mine somewhere on the autobahn last year, that said I’ve found the bag is showerproof, so it’s never let water. I like the fact the bag’s not bike specific, I’ve used it on a couple of my bikes, only issue is, you do need to buy mounting kits to fit, as fuel cap sizes aren’t universal."

Pros

  • It's easy to fit
  • The perfect size
  • It's showerproof without the cover

Cons

  • Badly fitting rain cover

Tried and tested by Dan Sutherland for one year and 2,000 miles

"It’s well made, feels robust, is stable at speed, and you can grab whatever you need without getting off the bike. As such, I’ve left it in place for thousands of miles aboard my Suzuki GSX-8S. It was particularly handy on a week-long tour to the 2023 Isle of Man TT races. With space to store your essentials, as well as things like passports and breathalysers on a longer foreign tour, I’d happily recommend it to anyone – performing well on my daily commute and staying solid during a 125mph blast across the TT’s one-way mountain section."

"Although I wouldn’t trust it to be 100% waterproof, it does feature water-resistant zips, with a main cubbyhole, key compartment, and an upper pouch with a clear screen and sun visor – a perfect place for a phone or satnav. There’s also a small gap for you to route a cable out the front of the pack, allowing me to plug a charging lead into a USB-C port mounted on the bike."

"A headstock strap, complete with a helmet-style Double D-ring fastener helps keep the bag securely in place. Although easy to fasten, it does dangle annoyingly when off the bike – meaning I’ll often tie it in a knot to stop it dragging. This is paired with a fixed, bike-specific metal plate (costing an extra £19.99) that attaches around the rim of the petrol tank – allowing you to click the bag in place bothbquickly and securely. Disconnected with a chunky red lever on the right, it can sometimes be a struggle to match the base plate to the gaps in the bottom of the tank bag when fitting."

"Some won’t like the look of the mounting metalwork when then luggage isn’t attached. A magnetic base is available as an alternative. After plenty of use, some of the blue material is beginning to show a few splodges of staining from road muck, but besides that it still looks and performs as good as new – with the chunky carry handle providing additional practicality off of the bike."

Tried and tested by Joseph Wright for three months and 2,000 miles

"The SW MOTECH PRO range offers a sporty and aerodynamic shape, with ballistic nylon material, looking well at home attached to bikes that are meant to go fast. The magnetic pro tank ring can be fitted to your fuel tank in under five minutes via the four screws. You can then helpfully reposition the bag on your bike using the upper ring guide rail, allowing for a flush fit. Once adjusted to suit you can simply throw this bag on your tank and it will hold in place with reassuring strength.

"The bag has an expandable main compartment, but also an additional two exterior side zip pockets plus two interior pouches and, as if this wasn’t enough, the lid has a further integrated zip pocket. For me it has the ideal amount of storage (12 litres) but if you ever get caught in a jam you can undo the expansion zipper raising the storage capacity to 17 litres. I have found it to be just tall enough to lean on when grinding through the motorway miles, but with a slim profile that isn’t restrictive when hitting the twisties."

"The fact that you can expand this bag by that additional five litres means that you can have it at maximum height when needing the support for your wrists and the storage, but also flat and aerodynamic when you are leaning off the bike. The only extra thing I had hoped to see in the box was a smartphone dry bag. This is available to purchase separately (which is what I did) and fits snug using the included Molle attachment system. I have been incredibly impressed by this product, as it’s made longer-distance riding far more practical without spoiling the riding experience or the looks of the bike. Makes riding a pocket rocket more comfortable, too."

Pros

  • Ideal to take weight off wrists
  • It's easy to fit
  • It's a great size

"You can’t beat a good tankbag, and SW Motech make some of the best. This ‘PRO’ system adds a self-guiding magnetic mount to their long-established tank ring mounts, which I’m testing with their 6-9L expandable Daypack."

"It’s superb in use. Simply glide the tankbag (there are seven styles to choose from, climbing from 3L to 25L in capacity) over the tank ring and it’ll suck the bag down onto the locking ring where it snaps in place with a reassuring clunk. Once located, it won’t come off without you pulling the red cord to force it to release its vice-like grip. The tank ring is unobtrusive when not in use, and the system makes refuelling a doddle."

"The bags are superb quality, too. They’re built, rather than made, and I’ve covered many thousands of miles with them without any failures or degradation – or even serious wear. I’ve used other SW Motech tankbags for over 40,000 miles on multiple bikes, and they still look nearly new. If you have multiple bikes, you will need a ring on each – but only one bag."

"The outer is tough and protective, highly UV-resistant 1680D ballistic nylon, the inner boasts useful pockets and compartments, the zips are durable… everything just works. I like the understated techy styling, too. The only faff is the separate rain cover, but I can attest to its effectiveness in even the harshest of persistent rain. Pricey, yes – but worth every penny."

FAQ

How does a tank ring attachment work?

The tank attachment ring will screw into the fuel filler cap ring. This allows the tank bag to be locked onto this ring keeping it secure.

What is the benefit of a ring attachment over magnetic?

The ring style attachment does not come into contact with the paintwork of the tank. A magnetic attachment could scratch paintwork on the fuel tank.

What size tank bag should I buy?

The main thing to bear in mind is that if you fit a large tank bag this could get in the way of your reach to the bars and restrict your steering movement.

How MCN tests tank bags

At MCN, our team of expert journalists have decades of experience gained over hundreds of thousands of miles in order to provide you with opinions and evaluations you can trust, alongside news of the most significant developments in motorcycling safety gear. We want you to stay safe, enjoy your riding and hopefully look great while doing so! 

We don’t test our kit to destruction; we use it exactly how you do, in the real world and in all conditions.

That means we can deliver impartial buying advice you can rely on. To make it onto this list, tank ring bags must have been used for thousands of miles by our team of experienced testers, show no major flaws as well as offering decent value for money. 

Each of our expert reviewers tests their tank bags for a variety of things, both subjective and objective. Factors assessed include the tank ring bags fitment, how secure they are with weight in, what pockets and compartments they have, how heavy duty they are and if they include details such as a waterproofing or expandable capacity.

We cover thousands of miles with these tank bags and regularly compare them with one another in the office, so collectively we’ve built the sort of knowledge base you can trust.

If you can’t see a review against a tank ring bags on this page, it’s because we haven’t tested it yet. These tank bags will only be included if we think they’re important and relevant in the market, and rest assured, we will be working on bringing you a review as soon as we’ve done the miles.

Here’s a brief run-down of the star rating system we use, and what each score means:

  • 1 star – Poor performance in this category or overall. A tank bag with a single star rating has fallen below the expected standard and should be avoided.
  • 2 stars – Basic performance in this area or overall. A tank bag with a two-star rating has managed to perform to a barely acceptable level and there is room for improvement. It might be lacking safety features, be poorly built or far too expensive to recommend.
  • 3 stars – An average performance in this area or overall. A tank bag with a three-star rating has achieved a basic level of performance and is deemed adequate.
  • 4 stars – A tank bag has performed over and above the accepted averaged in this category or overall. A helmet with a four-star rating has surpassed expectation and delivered in a particularly impressive way.
  • 5 stars – A tank bag has performed at the highest possible level in a particular category or overall. A product with a five-star rating has delivered to the highest possible level, impressing the tester with its performance. We would happily spend our own money on it.
