Choose The Right Air Pressure
1.To get the best performance from your K2
Razorback, it is necessary to adjust the suspension.
The first step is to set up the bike with the correct
air pressure.
2.The Spring Rate Chart as shown below is a good
guide line to get the correct air pressure. Note: Due
too a running change on the shock the spring rate
chart on the chainstay is not accurate, see fig 1.
3.The proper air pressure is a personal preference
and varies upon your weight and riding style. It may
take several rides to determine the optimal air
pressure.
4.The valve closest to the bike is the air spring
valve, Fig 2. The valve that is located near the red
rebound adjuster is a bleed valve and should always
be set to 0 Psi.

Rebound Adjustment
•All K2 Razorbacks have a shock with rebound
adjustment.
•Rebound damping is adjusted by the red rebound
adjuster knob.
• Rebound damping controls the speed at which the
shock returns to its original position after the
shock is compressed.
•The shock has 12 clicks of adjustment from fully
closed. Turning the knob clockwise will cause the
rebound to be slower.
•The proper rebound setting is a personal preference
and varies upon your weight and riding style.
•Experts agree that rebound should be as fast as
possible without kicking back and pushing the rider
off the saddle when riding the bike in rough terrain.
If rebound is set too slow, the suspension will not
have the time to extend before hitting the next bump
• Note: When the red rebound wheel is advanced to
positions towards full in, or full clock-wise, the
blue lock-out lever will feel slack or such that
minimal or no force is applied by the adjuster
rod. This is not a functional fault
Lockout Lever
1.All Razorbacks come with a shock that has a
lockout lever.
2.The purpose of the lockout lever is to eliminate
suspension movement when desired by the rider.
3.The shock comes with a safety blow-off valve. If
the bump force on the rear wheel is high enough the
blow-off valve will open and the shock will
compress.
