The picture shows a "natural"

The tank I received was a dirty yellow color that looks nothing like the picture. If the tank pictured was white than there should be a white option. I will use the tank and try not to think about it again,but it would be nice if the companies advertising these product would pay a little more attention and press the manufacturer for striker photos of there products there wouldn't be reviews like mine.

Surprise!!!! I need a whole new seat?

Bought the IMS 3.4 gallon tank for my 2001 wr426 and as I started installing it, I read the instructions and they indicated that I would need a YZ seat in ADDITION, because my original WR seat won't fit the new tank. Cost me 100 bucks more for a new seat and another week waiting for the seat to be shipped. Tank fitment was OK, not perfect, cap feels loose and flimsy compared to the stock tank and of coarse the shroud bolt holes didn't line up correctly. My radiator guards conflicted with the tank fitment on the right side that required some surgery. On the bright side the tank will have a slimmer feel to it more like the YZ. The WR tank and seat junction always felt bulbous and weird especially with my knee braces on. Looking forward to riding a little further on each full tank too. The waiting is the hardest part.

Good but not great...2012 WR450 Super moto

The bad news is: The tank is really yellow in color and while it is lightening up a bit I don't think it will ever be white/clear like it should.
It doesn't fit perfectly either but it is close and I was able to get it fitting properly with a little work.

The good news is: It looks okay on the bike and doesn't ruin the lines like some tanks do. The capacity is a nice change from the stock 2 gallon.

OK Fit

works great but the seat 'barely' fits up as it's very tight on my 05' EXC

Good buy

Got the 3.1gallon ims,for my '13 500 exc.install was fairly easy,good fit,but the radiator shrouds don't line up quite right.barely noticeable.didnt come with the mounting nut or petcock,luckily the guys at the local ktm shop used an acerbis kit and saved the day. No leaks,slim design,and fit perfectly with the moose radiator braces. Very happy with the 150 mile range I got kicks on more frequently on tight single tracks.but have no problems with overheating.natural color finish is a little off from stock,but not much,overall very pleased,I would recommend this tank.

Issues with all oversized gas tanks?

the shrouds didn't fit right for the IMS oversize tank and the seat barley fit. I googled "IMS oversize tank does not fit" and almost every make and model of bikes have some kind of fitting issue. To make things fair I google "Clarke oversize tank does not fit" and it is the same thing. with that being said, not sure what my next move going to be

Must Need for a 2 Stroke

I recently purchased a IMS tank and fell in love the second i put it on the bike. At first i thought that it might be to bulky and get in the way when trying to get on the tank in corners but after all its really good choice and i would recommend it to anyone who enjoys off road racibng

Not the best purchase ever.

it's easy to install, but the design is not good, you would see that the tank sides reaches a lower level than the center and when you ride your bike you would have fuel on the right side that won't be used because the fuel valve is on the left side, on the other hand the seat doesn't fit correctly, it pushes the seat like 1/2 of inch to the back. and the screws won't match the hole.

Motosport, never said you would need the YZ450F shrouds, on the description, so thats another issue i have to buy the yz450f 2006-2009 shrouds for my wr450f 2011.

IMS Desert Tank

My previous Acerbis tank got a leak and it was a bit too small for desert, so I bought this IMS 3.7 gallon tank. It's well built and fits pretty good. The radiator shrouds didn't fit perfectly on the tank but I was still able to get them on. Also, you can't access the spark plug (not on an '07 KTM 250sx anyway), but that was expected. After several crashes the tank seems the same as it was when it was new.

IMS WR250R FuelTank

I was going back and forth on an aftermarket tank for my 2011 WR250R between the IMS and the Safari. I decided on the IMS for the original appearance and smaller size.

The IMS is a direct bolt on and fit perfectly in the stock location with no modifications required. Simply remove the factory tank, swap over the fuel pump, and drop the IMS tank on the bike. A few of the stock tabs on the stock tank also get used on the IMS and IMS includes all the necessary hardware to make the change over simple.

The IMS tank is slightly wider and deeper than the factory tank and pushes the factory plastic out from seat about 1/2" on each side. The added width isn't noticeable and maintains a comfortable stance for sliding forward on the tank and standing.

The IMS Kit comes complete with all the fasteners you'll need as well as a new O Ring seal for the fuel pump.

I've been looking for a picture of this tank on a 400ex to see what it'll look like but cant seem to find any. Is the preview picture a picture of one that fits a 400ex ?
Expert MotoSport Staff
Over 8 months ago
The image is a generic image supplied by the manufacturer for reference only. It may not be displaying the exact part for your ATV. Once you select your 2005 TRX400EX it does appear to show the correct tank for the 400EX. IMS shows the tank on a 400EX on their site (see link)

I have a 2002 Wr250f. I have heard mixed reviews about how this tank will fit my bike. Will I need any aftermarket parts to fit this to my bike ?

The IMS gas tank will work for the bike is is designed for. With a 2002 model bike, you can have bent radiators, stretched frame and other aftermarket parts that can make installation a bit more difficult. That is to be expected.

You will reuse some of your OEM hardware for installation off the stock tank for sure.

No this is not the Zip Ty version, this would be to IMS specs. Unfortunately we do not carry the Zip Ty version but you can find it here:

Will this tank reduce the amount of air flow out of the radiators?
I noticed the tank is very close to the back of the radiators. Will this interfere with the air movement thru the radiators?

IMS designs each tank for a specific model/models of bikes. They are designed to work with the stock radiators, thus cooling should not be an issue.

Will this tank require me to buy a YZ seat???
I have a 2002 Yamaha WR250F. The Clarke tank requires that I get a YZ seat for proper fit on my bike. Will I need to get a YZ seat for this tank to fit properly to my bike as well or will the stock seat bolt up to this tank??
