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.
