MOTO KNEE2PERFORMANCE
A high-impact, durable, and highly adjustable prosthetic knee.
USERS MANUAL
FEATURES:
The Moto Knee was developed to be a high impact multisport knee with constant
flexion resistance. Because of this feature, it is not an ideal ‘everyday’ walking leg.
The key features that makes the Moto Knee2 unique are:
•Adjustable extension assist comparable to quadriceps function
•Adjustable hydraulic dampening for flexion and extension
•Patented linkage to allow 120 degrees of useable flexion
•Socket stop/bumper to prevent socket damage
•Multiple alignment options to improve performance
•Durable construction to withstand stresses from action sports
•Corrosion resistant parts for use in and around water
SPECIFICATIONS
ACTIVITY LEVEL: Unlimited
MAX. PATIENT WEIGHT: 250 lbs (114 kg)
KNEE WEIGHT: 3 lbs (1.36 kg)
BUILD HEIGHT: 9.65 in (24.51 cm)
KNEE FLEXION: Position 1 -120 deg
Position 2 –85 deg
-Four hole adapter on top and bottom of knee frame
2 Year Limited Warranty on
knee frame and components
1 Year Limited Warranty on
FOX SHOCK
Warning: Participating in any sport has certain
risks involved, which may cause bodily injury,
this is compounded even more for amputees
since they may not have the balance and
control with the prosthesis compared to a
normal leg/foot. Therefor, we advise you to
learn about the risks involved with each
activity and be sure to take the necessary
safety measures. The Alpine Foot alone, will
not guarantee athletic performance…. Though
with practice and the right tools, you can get
there!

Warning:
As with all knee prosthesis' there are multiple pinch points as the knee is flexed. The two main
pinch points are located between the knee frame and socket and inside the roller guide area.
Do Not insert fingers or any other object in these areas while flexing the knee joint

POSSIBLE ACTIVITIES
KNEE SET UP
Step 1: Connect the VF2 to the Moto Knee2
The ankle alignment/calibration varies depending on activity, refer to VF2 manual for alignment and
calibration. We suggest that the Moto Knee2/VF2 combo is about .5” shorter than the walking leg system to
allow better toe clearance. **Refer to Alignment Diagram for details.
Step 2: Connect the Socket to Moto Knee2
Start with centering the socket receiver onto the pyramid. At minimum, there should be a 15 degree angle
between the center line of knee and the centerline of the socket. Depending on the activity, this may increase
up to 30+ degrees.
Changes in knee flex can be accomplished through small adjustments on the pyramid or by increasing or
decreasing the length of the Push-Rod. See Push-Rod adjustment diagram for details.
•Loosen the 4mm sets-crew to unlock threads (1)
•Rotate Push-Rod eyelet (2) clockwise to shorten
and counterclockwise to lengthen.
•Make sure the flat side of threads are facing
toward the set screw before reassembly
•Insert Push-Rod back in desired mounting hole
and torque bolt
•Tighten Set Screw (1)

Step 3: Choose flexion range for preferred activity
Decide if maximum or minimum flex range is ideal for the
activity.
Position 1 -Allows 120 degrees of flex range from the extended
position
Position 2–Allows 85 degrees of flex range from the extended
position and will have more resistance at the start of movement
compared to position 1 .
Step 4: Socket Bumper Adjustment
The Moto Knee has an adjustable socket bumper
to reduce the stress of impact at max flex range.
When possible, if socket shape allows, adjust the
socket stop to contact the socket when the track
roller connects with end of travel. This splits the
potential impact load between the socket and
knee frame contact point and the track roller
assembly. There is an adjustable slide mount and
the socket bumper can also be rotated 180
degrees to achieve a higher level contact point.
Step 5: Air Spring Adjustment
The Air Spring gives the resistance to flexing under
weight. If you want it to be stiffer then add more air, if
you want it to flex easier then decrease the air
pressure.
Note: when threading air pump onto filler valve, the pressure from inside the shock pressurizes pump
which reduces the air pressure by around 5-8psi. Gauge is accurate when removing from valve.

Step 6: Hydraulic Flexion Adjustment
Blue Lever -Compression Adjuster (range of 3
clicks); Controls the flexion speed of the knee.
This adjustment makes a very noticeable
change. The stiff setting can act as a hydraulic
lock under slow movements but will flex under
quick loads. Most activities will be used in
medium or soft position.
Red Dial -Compression/rebound
clicker (range of 9 clicks); rotate this
clicker clockwise to slow the
compression and rebound. Example: if
the toe feels too ‘springy’ then rotate
clockwise to slow down the response. Black Dial -Compression micro-adjust
(range 3 clicks); This is a micro adjustment
that splits the blue lever options. You can fine
tune the compression resistance with this
option. Lift and rotate.
BASELINE SETTINGS
(based on a 180 lbs. amputee with moderate to high adaptive skill level)
Rebound adjustment (red dial)–closed position is when the dial is rotated clockwise until it stops. This position
closes/restricts oil flow which makes the shock extent slower

OUR
STORY
STARTS
HERE...
The Moto Knee2,Versa Foot2, VF2-HD, and Alpine Foot were created by Mike
Schultz, a professional snowmobile racer that lost his leg above the knee in 2008,
to an injury while racing. Unable to find prosthetic equipment to get back in
action and refusing to compromise, he created his own. His new designs allow
him to perform at a high level in all the sports he loves including snowboarding,
motocross, and snowmobile racing. BioDapt was established in 2010, to help
other amputees achieve their goals.
