Best Motorcycle Tank Bags in India
A tank bag is the most useful piece of luggage a motorcycle rider can add to a bike. It sits within arm’s reach, holds the things you reach for most often (phone, wallet, keys, sunglasses, toll cash, a small water bottle), and on most bikes it does not interfere with steering, fuel-cap access or the instrument cluster the way a saddlebag or a backpack can. For Indian riding conditions, where fuel stops, toll plazas and sudden weather changes come bundled into every long ride, a well-designed tank bag is less a luxury and more a working tool.
The Indian tank-bag segment in 2026 is consolidated around three brands: ViaTerra, Rynox and Guardian Gears. ViaTerra covers the ₹2,299 to ₹3,399 bracket with two mounting philosophies (strap and magnetic) across the Oxus and Fly line. Rynox sits at the top of this shortlist with the Optimus 3, a 21-litre hybrid bag priced at ₹3,900. Guardian Gears competes on price with the SideKick Universal at a sale price of ₹1,599. This guide compares all five bags on the criteria that actually decide which one you should buy: mounting type, capacity, waterproofing, build material, versatility and price.
What to Look for in a Motorcycle Tank Bag
Mounting type: Magnetic bags are quick to clip on and off but only grip steel tanks; they cannot mount on the plastic or fibre shrouds used on most modern ADVs and many modern commuters. Strap bags are universal but slower to install and can chafe paint if routed badly. Hybrid bags (magnets plus quick-release straps) are the safest compromise if you own more than one bike or plan to upgrade.
Capacity: 13 litres is the right size for a daily commute (wallet, phone, sunglasses, a small water bottle, a folded rain jacket). 15 to 18 litres is the sweet spot for a weekend ride. Anything over 20 litres is touring territory but starts to interfere with the handlebars at full lock on smaller bikes. Buy for the ride you actually do, not the ride you imagine.
Waterproofing: Almost no Indian tank bag is 100 percent waterproof on its own. Every bag on this list ships with a seam-sealed rain cover, but water can still seep from the bottom in heavy monsoon rain. For serious touring, pack electronics in a separate dry bag inside the tank bag. A charging-port passthrough is a useful feature if you also run a USB charger on the handlebar, but it is not a substitute for waterproofing.
Build material: Look for at least 1200-denier polyester exterior with EVA foam panels for shape retention. 1680D (Rynox Optimus 3) is denser and more abrasion-resistant. 900D (Guardian Gears SideKick) is acceptable at the budget end but will show wear sooner. YKK zippers and bar-tacked stress points are the markers of a bag that will last.
Versatility: A bag that converts to a backpack or a tail bag extends its useful life. The ViaTerra Fly Magnetic and the Rynox Optimus 3 both convert to backpacks with hidden straps. A transparent touch-sensitive top pocket for phone navigation is useful only if your bike’s tank shape puts it at a readable angle; on some bikes a dedicated phone mount is the better answer.
Price and warranty: The price band on this list runs from ₹1,599 to ₹3,900. ViaTerra backs its bags with a 12-month warranty; Rynox covers the Optimus 3 for only 6 months; Guardian Gears lists its warranty per-product on the product page. A longer warranty matters because tank bags take continuous vibration, sun and fuel-spill exposure.

1. ViaTerra Oxus 13L Universal Tank Bag, Strap Based
Price: ₹2,299
Type: Strap-mounted, universal
Capacity: 13 L (non-expandable)
The strap-based Oxus is the universal entry point to ViaTerra’s tank-bag range. The three-point strap mounting is designed to work on metal tanks and on the plastic or fibre tanks used on bikes like the Royal Enfield Hunter 350, the Yamaha FZ V3 and the KTM 390 Adventure. That universality is the single biggest reason to choose it over the magnetic version.
The build is 1200D polyester with EVA foam panels for shape retention, a 70D inner lining with PVC coating, and a faux-leather bottom to reduce tank scratches. Features include a touch-sensitive transparent top pocket that works even with the rain cover fitted, a cable inlet for charging a phone inside the pocket, two side pockets, an inner mesh pocket for documents, and an outer EBC net for gloves or rainwear. A removable strap converts it to a sling bag. The rain cover is seam-sealed; the bag itself is water-resistant, not 100 percent waterproof.
What stands out: Genuine universality (verified by buyers on Hunter 350 and FZ V3, sturdy 1200D construction with bar-tacked stress points, and a price-to-feature ratio that is hard to beat at ₹2,299. The transparent top pocket accepting touch input through the rain cover is a thoughtful detail.
Things to consider: 13 litres is small for anything beyond a day ride. Strap routing under the headstock can be fiddly on bikes with awkward tank shapes. The transparent top pocket is not always at a readable angle depending on your bike and your height. The rain cover protects the top and sides but water can seep from the bottom in prolonged heavy rain.

2. ViaTerra Oxus 13L Magnetic
Price: ₹2,799
Type: Magnetic, steel-tank only
Capacity: 13 L (non-expandable)
The magnetic Oxus is the same 13-litre body as the strap version, mounted on four sets of compound rare-earth magnets on the base instead of straps. It is designed for riders who want zero-fiddle mounting on a steel tank, and who value the speed of clipping the bag on and off at every fuel stop.
Build, features and rain cover are identical to the strap version: 1200D polyester, EVA panels, touch-sensitive transparent top pocket, cable inlet, sling-bag conversion, faux-leather base, seam-sealed rain cover. The 12-month ViaTerra luggage warranty applies. The bag also ships with two rear mounting straps and a front strap retainer for use as a tail bag.
What stands out: Mounting is genuinely quick and the EVA panels hold shape well enough that the bag does not interfere with the handlebars or the odometer on the bikes it fits. The faux-leather base does not scratch tanks the way a bare magnetic base can.
Things to consider: Magnets only grip steel tanks. Long-term magnet durability is a recurring complaint across all magnetic tank bags, with users reporting that holding power can drop after roughly a year of daily use, causing the bag to slide on inclined tanks. Magnets can also trap metal debris that scratches the tank if the base is not wiped before mounting.

3. ViaTerra Fly Magnetic 18L
Price: ₹3,399
Type: Magnetic, steel-tank only
Capacity: 18 L (non-expandable)
The Fly is the step-up bag in the ViaTerra magnetic range. Capacity rises to 18 litres, the magnet count rises to five sets of compound rare-earth magnets for better stress distribution, and the build adds 300D rip-stop fabric with PU and water-repellent coating on top of the 1200D base fabric. The internal lining is the same 70D fabric with PVC coating. The shape is wider and longer than the Oxus (42 cm long edge, 35 cm wide edge, 10 cm height) and it carries a 1.1 kg weight.
Feature-wise the Fly is the most complete bag on this list: touch-sensitive transparent top pocket, cable inlet, inbuilt hidden straps for backpack conversion, detachable straps for tail-bag conversion, EVA foam panels with PP inserts for shape retention on potholed roads, two side pockets, an inner mesh pocket, an outer EBC net for gloves, and a wide top U-opening for easier packing. The faux-leather base is retained. The seam-sealed rain cover is included.
What stands out: Capacity is enough for a 14-inch laptop or tablet plus a change of clothes for a weekend trip. The three-in-one conversion (tank bag, tail bag, backpack) makes the Fly useful off the bike as well as on it. The five-magnet layout holds better than the four-magnet Oxus on inclined steel tanks.
Things to consider: Steel-tank only, same as the Oxus Magnetic. At 42cm by 35 cm the Fly can interfere with the handlebars at full lock on smaller bikes if overstuffed. Long-term magnet durability concerns apply, and the base can scuff the tank in heavy off-road vibration or strong crosswinds if debris is trapped between bag and tank. The 1.1 kg empty weight is heaviest in this shortlist after the Optimus 3.

4. Rynox Optimus 3 Tank Bag 21L
Price: ₹3,900
Type: Hybrid (5 magnets + quick-release straps), universal
Capacity: 18 L expanding to 21 L
The Optimus 3 is the most expensive bag on this list and also the most universal. Rynox uses a hybrid mounting system: five powerful monopole magnets for steel-tank use, plus quick-release straps for plastic-tank bikes. Rynox itself recommends using both magnets and straps together when the bag is loaded at full 21-litre expansion. That hybrid design fixes the single biggest weakness of magnetic tank bags, which is the tendency to slide on inclined tanks or in rough-road vibration.
Build is the densest on this list: 1680D polyester (versus ViaTerra’s 1200D and Guardian Gears’s 900D), genuine YKK hardware throughout (D-rings, ladder locks, snap hooks, glove-friendly zipper pullers), and an anti-scratch rubberised PU foam base. Features include a transparent touch-friendly smart-device pocket, two side pockets, a quick-access top pocket, an under-flap mesh pocket, compression straps inside the main compartment, tuck-away backpack straps, and reflective trims for night visibility. The three-in-one form factor (tank bag, tail bag, backpack) is shared with the Fly.
What stands out: Genuinely universal mounting that works on every bike in this shortlist’s target audience. The 1680D fabric and full YKK hardware give the sturdiest feel of the five bags. Expansion from 18 to 21 litres is the only expandable design here. The anti-scratch PU foam base is the most tank-friendly base on the list.
Things to consider: Warranty is 6 months from delivery, half of ViaTerra’s 12 months. The reflective trims are reportedly not durable, with one verified buyer noting that the radium quality needs improvement. The bag is bulkier and heavier than the 13-litre ViaTerra options, and at full 21-litre expansion it can interfere with the handlebars on smaller bikes. Older Optimus variants had magnet-holding issues on inclined tanks; the Optimus 3 fixes this with the strap backup but you should still use both mounting systems when the bag is loaded.

5. Guardian Gears SideKick Universal 15L
Price: ₹1,599
Type: Strap-mounted, universal
Capacity: 15 L
The SideKick is the budget pick on this list. Guardian Gears is the only brand on this shortlist that has not previously been featured on MotoDune, so a brief introduction: it is a Pune-based luggage maker with a wide range of saddlebags, tail bags and tank bags aimed at the value segment. The SideKick is positioned as the brand’s tank-bag hero and the price makes that positioning explicit.
Build is 900D PVC-coated water-repellent fabric, original YKK zippers, a 3M reflective strip, a custom inner liner and a waterproof rain cover. The strap system is non-magnetic and rated for a 150 to 200 kg load, which is a generous safety margin for a 15-litre bag. The strap design fits both metal and plastic tanks. No transparent phone pocket or charging passthrough is listed in the product description.
What stands out: At ₹1,599 on sale, the SideKick is the most affordable tank bag on this list by a clear margin. Genuine YKK zippers and a 3M reflective strip are quality components at this price. The strap system is genuinely universal and the 150 to 200 kg strap load rating inspires more confidence than the strap systems on similarly-priced bags. The single verified site reviewer reports that build quality is good.
Things to consider: The 900D fabric is lower-denier than ViaTerra’s 1200D or Rynox’s 1680D and will show wear sooner. The strap system is reported as “a bit irritating” by the only verified reviewer, who wished for a velcro-based alternative. There is no transparent phone or map pocket, no charging passthrough, and no backpack or sling conversion. The warranty period is not clearly stated on the product page and must be checked in the per-product warranty dropdown at checkout.

How to Choose the Correct Tank Bag Size
For daily commuting: 13 litres is the right size. It holds wallet, phone, sunglasses, a small water bottle and a folded rain jacket without obstructing the handlebars or the fuel cap. Anything larger becomes a nuisance in city traffic.
For weekend rides: 15 to 18 litres is the sweet spot. It adds room for a small camera, a power bank, snacks and a light layer, without pushing into handlebar-interference territory. The ViaTerra Fly Magnetic and the Guardian Gears SideKick sit in this band.
For multi-day touring: 20 litres and above is touring territory. The Rynox Optimus 3 at 21 litres is the only true touring option on this list. Pair it with a saddlebag or a tail bag for clothes, and keep the tank bag for items you reach for during the ride.
For pillions and pillions-only bikes: Skip the tank bag entirely and use a tail bag on the rear seat. A tank bag interferes with the rider’s chest on a committed riding position and leaves less room to lean forward in stop-and-go traffic.
What to Avoid When Buying a Tank Bag
Avoid buying a magnetic bag for a plastic tank: The magnets will not grip. This is the single most common buying mistake in the Indian tank-bag segment. Check your tank material before you order.
Avoid oversizing for your bike: A 21-litre bag on a 150 cc commuter is unrideable in traffic. Match the bag to the bike’s physical size, not to your touring fantasies.
Avoid bags without a rain cover: Every bag on this list includes one, but cheaper unbranded bags often do not. In India, a tank bag without a rain cover is a single-monsoon purchase.
Avoid routing straps over painted surfaces without protection: Use a foam pad or a cloth under the strap where it contacts the tank. Bare strap over paint is the fastest way to scuff your tank.
Avoid leaving the bag on the bike in direct sunlight for days: Polyester and EVA foam degrade under continuous UV exposure. If you park the bike for more than a day, take the bag off and store it indoors.
Frequently Asked Questions
Which is the best motorcycle tank bag in India for touring?
The Rynox Optimus 3 21L is the strongest touring pick on this list. It is the only expandable bag here (18 to 21 litres), it uses a hybrid mounting system that works on both steel and plastic tanks, and it has the densest build (1680D polyester, full YKK hardware, anti-scratch PU foam base). The trade-off is the 6-month warranty, half of ViaTerra’s 12 months.
Can a magnetic tank bag be used on a plastic or fibre tank?
No. Magnetic tank bags only grip steel tanks. Bikes like the Royal Enfield Himalayan 411, the XPulse 200 4V, the Hunter 350, the KTM 390 Adventure and the Jawa use plastic tank shrouds. For these bikes, choose a strap-mounted bag (ViaTerra Oxus Strap, Guardian Gears SideKick) or a hybrid bag (Rynox Optimus 3).
Are these tank bags waterproof?
No bag on this list is 100 percent waterproof on its own. All five ship with a seam-sealed rain cover, but water can still seep from the bottom in prolonged heavy rain. For multi-day monsoon touring, pack electronics in a separate dry bag inside the tank bag.
What is the cheapest good tank bag in India?
The Guardian Gears SideKick Universal 15L at ₹1,599 on sale is the cheapest bag on this list. It uses genuine YKK zippers and a 3M reflective strip, and the strap system is genuinely universal. The trade-off is the 900D fabric (lower than ViaTerra or Rynox) and only one verified buyer review on the official store.
Do I need a phone mount if my tank bag has a transparent top pocket?
Not always, but often yes. The transparent top pocket works as a navigation screen only if your bike’s tank shape puts it at a readable angle. On many bikes the pocket sits too low or too far forward. If navigation is your primary use case, a dedicated phone mount is the safer answer and the tank bag can be used for storage.
How long do magnetic tank bags last before the magnets weaken?
Based on aggregated user feedback, magnetic holding power can drop noticeably after roughly a year of daily use, especially on inclined tanks or in rough-road vibration. The Rynox Optimus 3 mitigates this with its strap backup. For ViaTerra magnetic bags, check the magnet grip periodically and clean the magnet base of any trapped metal debris.
Can I use a tank bag as a backpack off the bike?
The ViaTerra Fly Magnetic and the Rynox Optimus 3 both convert to backpacks with hidden straps. The ViaTerra Oxus (both versions) converts to a sling bag with a removable strap. The Guardian Gears SideKick does not have a backpack or sling conversion.
Final Thoughts
The Indian motorcycle tank-bag segment in 2026 is well-served at every price point. ViaTerra’s Oxus and Fly range cover the ₹2,299 to ₹3,399 bracket with two mounting philosophies and a consistent 12-month warranty. Rynox’s Optimus 3 is the universal touring pick at ₹3,900, with the densest build and the only hybrid mounting on this list. Guardian Gears’s SideKick makes the category accessible at ₹1,599, with the expected compromises in fabric and feature count.
If you ride a steel-tank bike and want one bag that does everything, pick the ViaTerra Fly Magnetic 18L. If you ride a plastic-tank bike or you switch bikes, pick the Rynox Optimus 3 21L. If you are buying your first tank bag and you want to keep the spend low, the Guardian Gears SideKick is the entry point and the ViaTerra Oxus Strap at ₹2,299 is the safer step up.
Whichever you choose, compare the complete specification sheet against the price, not the price alone. A tank bag is a working tool that takes daily sun, vibration and fuel-spill exposure; the denier count, the zipper brand and the warranty period matter more than a ₹300 difference at the checkout.
