Acerbis Tank Warranty:

ACERBIS stands behind their products against manufacturer defects. In situations where a crash occurs, a solvent, liner or paint is applied, a product is improperly installed, or in a case of general neglect, ACERBIS is not liable and all warranties are void.

  • Paint that is added to the interior or exterior of any ACERBIS fuel tanks will in turn void any and all warranties. ACERBIS' tanks are made from polyethylene, which is a porous material that allows fuel vapor to escape. The minimal vapor that vents through is normal and will not affect the performance of the tank.
  • Vinyl wraps and or stickers will also impede the tank's ability to vent and should not be used. And, they can also vapor lock the vehicle. In most if not all cases, the wrap or sticker will bubble from the escaping fumes.
  • Internal coatings added to ACERBIS tanks are not recommended and should be avoided. ACERBIS tanks are perfectly functional and do not require the addition of internal coatings. Polyethylene can react negatively to a variety of chemicals so applying any second-party products will void any and all warranties.
  • If an ACERBIS tank is punctured in the event of a crash, ACERBIS is not liable for replacement.

Perfect fit! Super easy to install.

The 2.9 gallon fit perfect on my 2008 crf450. I have radiator guards but all you have to do is flip them upside down and the tank fits perfect. No cutting or grinding needed.

I have a 1994 suzuki dr 350 se model and this tank was listed for the s model and they didn't list the se in their fitment chart. I asked if it would fit mine and they couldn't say for sure but said if it didn't I could return it. I purchased this tank and it was a perfect fit. Great tank and great place to do business with! Thanks for everything

Smaller than advertised

A bit disappointed as this was described as a 4.25 gallon tank but after two fills from empty at two different gas stations, it only holds 3.8 gallons. This is on a Suzuki DR350. I do like the dual petcocks though, and it's well built and fits good.

Looks great

Acerbis replacement tank. Looks & fits great easy install on my KTM 450 XC-f the black looks way better than the natural tank that came on it I got the 3.1 gallon tank not needing anything bigger really nice my second experience with acerbis and I love them they give you plenty of hardware that you don't even need but just in case

Installed this tank on my new bike. Easy to install and I really like the extra gas and the look on the bike. It fills in the void space and makes it look beafier. Make sure and get acerbis locking gas cap to it has a check valve built into it so you don't have to deal with a vent hose

Overall great product

This acerbis tank was an amazing addition to my CRF250L. The tank is made out of great quality plastic. Installation wasn't too difficult, but did have a few speedbumps. One, the fuel pump has to be inserted reversely compared to how the tank is stock, and there were some fitting difficulties that were easily fixed. Plus, the extra mileage is always nice. The longer time out riding, the bigger smile appears on the face, and riders are happy. Great product!

Honda CRF250X

This product is not made for the Honda CRF250X, it is for a Honda CRF250R!

That being said, and the fact that the frames ARE different, this tank will fit but requires a hole approximately 7/8 of an inch below the stock mounting hole. 5mm drill/6 mm tap will do the trick in minutes and the look is great!

Just think of the new hole as weight savings :)

Very Good Not Great 2004 YZ450f

I bought this tank for extra fuel capacity. It's a good design and fits well. The original seat fits well with the new tank and the bike is still comfortable to ride. I'm generally happy with this tank.

I do not like the fact that the valves attach to the tank with lag screws instead of threaded inserts. Also the plastic T-fitting include with the plumbing kit is garbage and should be replaced with a metal fitting.

3 gallon on 500 exc

It's a good thing to have more fuel, but somethings you need to know are 1: it will not fit unless you do a smog delete to remove the can. 2:: it is pretty tough to get your factory plastic back on, but it can be done. 3: it will fit with radiator braces and a fan. It looks fine but is more yellow than I'd like. I also don't care for the pump being mounted by plastic screws instead of into metal thread inserts. All in all I needed a bigger tank and to keep my six days looking stock and it worked

High Quality tank

Very nice fit with the exception of the airbox covers. This tank was designed for 2013 and prior years, my 2014 required airbox covers (additional $30) from a 2013 and then the fit was perfect. Came with all the fittings and hardware for installation. Tank is definitely wider up near the built in shrouds, tank/seat junction is nearly the same as with the stock tank. It easily cleared the cooling fan and Enduro Engineering radiator guards. Claimed capacity was 4.1 gallons, actual capacity is 4.2 gallons.....bonus.

Awesome tank! Way better then the ims tanks

Acerbis does it right. Tank fit perfect on my 2007 Honda crf 450. I got the natural color. It's nice an clear not all yellowed like you find on ims tanks. If your gonna purchase any type of plastics for your bike stick with acerbis they been doing since 1973.

Poor design

I recently installed this on my 2006 KX450F for a Hare and Hound race. The quick fill cap malfunctioned and the spring loaded cap got stuck and did not allow fuel to enter the tank. The cap being stuck also allowed fuel to spill out which almost sanded me 30miles out in the desert. After working on the cap for several minutes I got the spring to wedge closed. This poor design cost me 15min overall on my time and almost left me stranded.

Great piece. 5.3 Gallons for my 2016 KTM 500 EXC sounds great. Easy install, complete kit. Wish there were more safari tank options for these bikes, but you get what you pay for.

Nice tank

Overall a great product! I love the slim line of such a large capacity tank. Finish is great, comes with easy to use directions and all required fittings. My only wish is that they would have made the fit next to the side covers more exact. there is a good 3/8" gap between the tank and the side covers. Word to the wise...when buying any new tank- flush that bad boy prior to install! Acerbis did a good job but I flushed out several curls and chips of plastic out of the tank- would have been a bad day if those clogged the filter/injector!

Oversize tank for 500 EXC

No complaints here. This tank fit like it should and all of the plastic attached to it without an issue. I followed the instructions and leaned it as requested but after close inspection before cleaning, it looked to be VERY clean inside. I spread a black cloth on the ground to catch any particles that may have been washed out but found none. I also wanted to make sure it held what they said it would hold which was 3 gallons. I took an empty gas can to the station and put exactly 3 gallons in it and it filled it up EXACTLY to the top so it definitely IS 3 gallons! Good product and definitely worth the money. MOTOSPORT was about $40 dollars cheaper than everybody else on this tank. Great deal!! Fast shipping!! Semper Fi......
