Notes: This is a 99mm Billet Aluminum cylinder that has a forged aluminum sleeve installed it is coated with Ceramic Nickel Bore. It also comes with an aftermarket stroker crankshaft. At 4mm over OEM bored cylinders have about a 20% failure rate, they last about 10 seconds with a stroker crank. That is why we designed the Ice Cube cylinder.
The Ice Cube Cylinder is the only aftermarket cylinder available that was designed for big bore applications right from the start.
Most of the cast big bore cylinders that are out there were originally designed as stock replacement cylinders. Once the big bore movement really took off around 2005 companies decided to machine and plate them oversize to sell to the budget big bore market. Most of these cylinders have less than 1/2 of the coolant capacity of the Ice Cube. (We know because we checked them). They also have skirts that fold like a house of cards when you put stroke to them.
The Ice Cube is made from 2 extremely dense forms of aerospace grade aluminum, billet and forged. Dense forged aluminum (the same grade as piston forgings) provides the highest level of strength and transfers heat faster than steel or even cast aluminum. These strength and heat transfer properties makes it ideal for this application where space is limited and stress is increased.
The latest version of the Ice Cube cylinder for the YFZ450 includes cylinder side wall re-enforcement bosses that keep your Ice Cube round and straight even in the most demanding of applications.
Each Ice Cube cylinder is machined to provide for a copper fire ring in the head gasket surface. This feature is only found on the Ice Cube and serves two functions. The first is to provide additional sealing in the combustion chamber. This makes head gasket failures a thing of the past. It also provides additional force to the cylinder liner and keeps it firmly seated in the cylinder counter bore and eliminates any sleeve shift under load.
The Ice Cube is also the only cylinder that has extended cylinder skirts that provide piston support at BDC (bottom dead center) for stroker cranks. Every other cylinder out there allows the piston to drop out of the bore at BDC. This advantage of the Ice Cube increases piston life dramatically in stroker applications.
The YFZ511 is a good choice for the customer who is looking for a big bore kit and also needs to replace the crankshaft. It does not build as much torque as the YFZ525 kit but it certainly will hold it’s own against most anything out there. Some customers actually like it more because it winds up slightly faster than the YFZ525 and provides more torque than the YFZ488.
The addition of this kit not only will raise the value of your machine but it will set you apart from the crowd as an owner that is not willing to compromise on performance. The Ice Cube Cylinder means quality and value backed by Max Power support.
The Ice Cube is coated with Max Power’s Ceramic Nickel Bore coating. It is the best plating available and Max Power’s plating craftsmanship far surpasses the quality of anything else out there.

This kit can make a yfz one impressive beast. I have a race port, full sparks, fcr intake with a stock dyna three way ignition. fifty three ponys by the dyno. I beleive the carb is the issue. I need to have mine bored. The torque is awesome, not to the point of being too violent though. Pretty good deal. According to my shop I’ll get another five or so with the carb bored. Top end is where I drop off but the low end is solid until entering third gear.
