Rear Irazr - I have tested them in muddy conditions, dry, wet hardpack, MX, wet grass, dry grass, rough woods, rocks and many other conditions. I have ridden and raced them both new and worn out now.

When they are new (4 hours or less):

They have the best forward bite of any tire I have ever ridden. They have good side bite when accelerating in a corner but not as controllable as a regular Razr in aggressive cornering, but still better then the Razr2.

They hook up so well that you will have problems with the front end pushing in the corners untill you learn to put your body weight further forward on the bike to turn.

When they are worn out:

They have better forward bite then either the Razr or Razr2 in most conditions. They have poor side bite in wet hard pack.

In all conditions: They have a better quality ride & and allow us to run Nitrogen in the tires in addition to the tire balls without getting as ridged as a bias ply tire.

Overall opinion - while we may not run them at every race - your will not find us at a GNCC with out a set ready to run. They are a step forward in tire technology for ATV racing and riding.
