Choose Acerbis gas tanks by the exact dirt bike or dual sport application before capacity, color or cap style. Fit comes first.
For the 6.6-gallon option, one named product page specifies polyethylene, a raw finish, Dry Break and Standard cap styles, included mounting hardware and model-specific MDR cap notes.
What to Compare in Acerbis Gas Tanks
PirateMX carries new aftermarket Acerbis gas tanks for dirt bikes and dual sport bikes. Start with the motorcycle.
Once you find the correct application, compare capacities of 3, 3.1, 4, 6.1, 6.3 and 6.6 gallons. Capacity by itself does not confirm fitment.
Product names may show black, red, orange or Nat, while the exact page can state a separate surface finish. Color will not settle the application.
More capacity can stretch the distance between fuel stops during trail riding or dual sport use, but the extra fuel adds weight when the tank is full. Tank shape can also change knee room and how freely you move around the bike. For moto or a track day, carrying fuel you do not need may work against the lighter feel you want.
After choosing the machine path, read the product page for capacity, cap setup, material, finish, included hardware and any installation note.

Start With the Motorcycle You Have
Use the make that matches your machine: Harley Davidson gas tanks, Honda gas tanks, Yamaha gas tanks, KTM gas tanks, Polaris gas tanks or Kawasaki gas tanks.
That is only the starting path. A make page does not prove that a particular capacity, color or cap configuration belongs on your motorcycle.
For a dirt bike or dual sport, read the fitment chart and specifications on the product page before comparing tank size. Check fitment for your exact year, make and model before you order.
What the Acerbis 6.6-Gallon Tank Page Specifies
The Acerbis Oversized Fuel Tank 6.6 Gal Nat gives a useful product-specific example. Its page states a capacity of 6.6 gallons, Dry Break and Standard cap styles, polyethylene material, a Raw surface finish and included mounting hardware.
Those details apply to this tank only.
Dry Break matters when your race-prep fuel can uses that connection. Standard fill matters when you are filling without dry-break gear, such as during regular trail riding or between dual sport fuel stops.
The page identifies polyethylene as the tank material. It calls the surface finish Raw and does not state a painted finish.
The product notes say an MDR gas cap is included on some models, and that the MDR cap can use dry-break gas cans or standard fill. They also say all necessary hardware and a new MDR gas cap are included. Recheck how the model-specific cap wording applies to the exact tank you are considering.
Pre-season and race-prep check
- Application: Match the fitment chart to the motorcycle, not just the capacity or color.
- Fuel load: Decide whether the extra range is worth the full-tank weight and any change in bike feel.
- Cap setup: Match Dry Break, Standard and MDR wording to the cans or pump nozzles you use.
- Material and finish: Read what the exact product page states rather than carrying this tank's polyethylene and Raw specifications to another version.
- Box contents: Confirm the included cap and mounting hardware, then read any model-specific installation note.
If the page does not explain a detail you need, ask PirateMX before ordering.
When to Compare Acerbis With Other Gas Tank Brands
If you came looking for Acerbis gas tanks, keep that brand as your starting point. Define the motorcycle application, needed capacity, cap setup, material, finish and included hardware before comparing other options.
PirateMX also carries Drag Specialties gas tanks, Biker's Choice gas tanks and Harddrive Parts gas tanks. A different brand does not solve an application mismatch.
Compare each exact product page against the job your motorcycle needs to do. Confirm the tank configuration, box contents and installation notes before making the choice.
