Backed by the AMA, each year's series continues to get bigger and better... drawing bigger crowds, more sponsors and riders from all over the globe. The 2008 XiiR / AMA Championship Series, is also the ONLY Ice Racing series sanctioned by the AMA

Don't be fooled by the appearance of the Speedway Bike. It's more than just a mountain bike with an engine. It's engine is equivalent to a 1200cc crotch rocket engine in a mountain bike frame, 4-stroke, 4-valve engine that runs on nitro methanol. This allows the engine to run at a higher compression, producing more horsepower. The average car has a maximum 5,000 RPM's where as an ice speedway bike has a maximum 14,000 RPM's. It has 1600 razor-sharp steel studs on it's tires added for traction and if that's not enough - there aren't any brakes.

Four laps on a speedway bike compares to 10 minutes on a motorcross bike. The power (90 horse power at the back wheel) to weight ratio (the bikes weigh only 180 pounds) is something that cannot be explained.

Each rider gears his bike differently with 60 to 80 toothed sprockets, which are nearly the size of the wheel itself. Just wait until you see these machines in action!
There will be a total of twenty to twenty-five races. The amount of races will vary from city to city depending on how many local riders participate.

Ice Racing consists of heats where riders earn points to qualify for the Main (final race) Qualifying heats consists of 4 riders racing handlebar-to-handlebar for 4 laps.
