The Best Gas Tanks For Suzuki DR650, Reviewed
Acerbis 5.3 Gallon Fuel Tank
What We Like
- Larger fuel capacity than the stock tank
- Maintains standard riding position
- Includes all necessary mounting hardware
- Modern lines and high-quality construction
Trade-offs
- Slippery plastic surface needs grip pads
- Dual petcock setup requires drilling tank
The 5.3-gallon capacity transforms the DR650’s range without altering the riding position, a key upgrade for long-distance travel. Its modern lines incorporate high-quality construction and it fits with the factory plastics. The tank comes with a gas cap, petcock, and all mounting hardware for a complete installation.
The trade-off is that the smooth plastic surface can lack grip, a common issue noted by owners who often add aftermarket tank pads. For riders who need even more capacity, the Acerbis 6.6-gallon model is the logical step up, though it widens the bike’s profile. The IMS 4.9-gallon tank is a lighter alternative for those who prioritize a slimmer fit over maximum range.

Acerbis 6.6 Gallon Fuel Tank
What We Like
- Massive 6.6-gallon capacity for extreme range
- Endorsed by top riders worldwide
- Includes all necessary hardware
Trade-offs
- Not shippable to California addresses
- Wider front profile alters bike's ergonomics
The 6.6-gallon capacity is the single biggest fuel reserve you can bolt onto a DR650, transforming it into a true continent-crossing machine.
That immense capacity comes with real trade-offs. Its physical size also extends wider and further forward, which can affect rider ergonomics and requires relocating the front turn signals. If this bulk is a concern, the Acerbis 5.3-gallon tank offers a more moderate capacity increase with a slimmer profile.
IMS 4.9 Gallon Fuel Tank
What We Like
- Larger capacity than stock for greater riding distance.
- Slim and sleek design enhances motorcycle appearance.
- Made with durable polyethylene crosslink for extra strength.
- Natural color option allows easy fuel level viewing.
Trade-offs
- 4.9-gallon capacity is less than the Acerbis 5.3 and 6.6-gallon tanks.
- Weighs 9.5 pounds, adding permanent mass to the bike.
With a 4.9-gallon capacity, this tank provides greater riding distance than the stock unit, which is a major advantage for long rides or remote trails. IMS designs it to be very slim and sleek, enhancing the motorcycle’s appearance while adding volume. Made with polyethylene crosslink for extra strength, it’s built for durability in dunes or off-road racing. Choosing the natural color version, as research mentions recommend, lets you see the fuel level easily.
The trade-off for that slimmer profile is ultimate capacity; the Acerbis 5.3 and 6.6-gallon tanks hold more fuel for truly epic distances. This IMS tank is a balanced choice, delivering a substantial range increase without the bulkier dimensions of the largest options.
IMS Natural 4.9 Gallon Fuel Tank
What We Like
- Natural color allows easy visual fuel level checks
- Includes a redesigned cap resistant to modern fuel additives
- Available in multiple colors for personal preference
Trade-offs
- Capacity is less than the 5.3-gallon Acerbis model
- Weighs over nine pounds when empty
Its 4.9-gallon capacity significantly extends the touring range of the DR650SE, allowing for longer stretches between fuel stops. The natural color is specifically recommended for easily seeing the fuel level, which eliminates guesswork on remote rides. This tank comes with a cap and fuel petcock for a complete installation, and the cap is newly redesigned to resist damage from modern fuel additives.
You gain clear fuel visibility but not the maximum capacity, as the Acerbis models offer 5.3 and 6.6 gallons. For the rider who wants a substantial range increase without losing sight of the fuel level, this IMS option provides a practical middle ground. It installs with the included petcock and is built with a cap designed to handle today’s ethanol-blended fuels.
How We Evaluated Gas Tanks
Our evaluation is research-based, focusing on manufacturer specifications, installation documentation, and consistent patterns in rider feedback from forums and review platforms. We prioritized criteria that matter most for a functional upgrade: the increased fuel capacity over the stock 3.4-gallon tank, how the tank’s shape affects rider ergonomics and signal clearance, and the completeness of the mounting hardware kit. While research provides these insights, the final fit and feel on a specific motorcycle can vary, which is why we note where modifications like relocating turn signals may be necessary.
What To Look For In Gas Tanks
Choosing a replacement tank involves more than just picking the biggest option. You need to balance increased range with how the tank alters your bike’s handling and what extra steps installation might require.
The key is capacity versus fit. The stock 3.4-gallon tank is your baseline. Look for a design that delivers your desired range extension while maintaining comfortable ergonomics and coming with a complete hardware kit for straightforward installation.
Capacity
The core reason to upgrade is to gain more range. The Acerbis 5.3-gallon tank increases capacity by over 50%, while the massive 6.6-gallon option nearly doubles it. The IMS 4.9-gallon tank offers a solid middle ground. Consider your typical riding distances and how often you venture far from fuel stations; the larger the tank, the more you trade off in terms of added weight and bulk.
Ergonomics & Fit
A larger tank can change how you interact with the bike. The Acerbis 5.3-gallon model is designed to maintain the stock riding position. In contrast, the wider-fronted 6.6-gallon tank alters the bike’s profile, which some riders find affects handling, especially in tight terrain. A slim-profile tank like the IMS 4.9-gallon version aims for a factory-like feel, which can be a priority for riders who dislike a bulky appearance. Furthermore, some tanks require modifying turn signal mounts to avoid contact.
Installation & Upkeep
Check what is included. All top picks come with a cap and petcock, but some kits are more complete than others. For example, the Acerbis 5.3-gallon tank’s dual petcock setup requires drilling the tank, which is a permanent modification. Plastic tanks are durable but can have a slippery surface, making aftermarket tank grip pads a popular addition. Natural-colored polyurethane tanks allow for easy fuel level checks, a convenience feature.
- Check for included hardware: A complete kit with all bolts, brackets, and a petcock saves time.
- Consider signal clearance: Determine if you’ll need to buy and install separate signal relocation brackets.
- Plan for grip: If opting for a plastic tank, budget for adhesive grip pads to improve knee hold.
- Inspect the cap: Some modern caps are redesigned to better resist fuel additives.
The best upgrade balances the range you need with a fit that feels natural on your bike.
