tank uses the WR shrouds. There are several different tanks out there: IMS
, Clarke, Acerbis
and one other I believe. IMS sells an entire YZ seat ($125)or just a YZ seat base. The IMS foam, in my opinion, is softer than OEM
, but still pretty stiff. Some guys use a differant seat foam on their IMS YZ seat base. The YZ tank has a capacity of around 2 gallons. I, and several others have swapped to a YZ tank. I dearly love mine, although the extra gallon of fuel might be nice. If I go somewhere where I need the range, I'll put the OEM
tank and seat back on. Around home, I am fat (that would be fat, dumb and happy) using the YZ tank. It makes a HUGE difference if you ride on an MX track, and nicer everywhere else too (unless it is in the Mojave in the middle of no-where and you are sucking fumes in your tank).
