Attach your sidecar using a Universal Mount:
The Universal Mounting Kit makes it possible to
attach the sidecar to virtually any current motorcycle with round tube
frame, but the motorcycle should be powerful enough to accept
the weight of the sidecar, passenger, and extra luggage.
IMPORTANT: Deviating from the instructions
may create dangerous conditions. It is important to follow the
directions carefully, be thorough and use common sense. Each sidecar
operator is responsible for his/her own safety and the safety
of their passengers. For best results, we recommend soliciting
installation service from a qualified
dealer in your area.
Installation is a 4-5 hour process, involving these simple operations:
- Attaching the frame of the sidecar to the frame of the motorcycle.
- Adjusting toe-in and lean-out of the motorcycle in relation
to the sidecar.
- Connecting the electrical wires from the
sidecar to the electrical circuits of the motorcycle.
These operations are given in easy-to-understand step-by-step procedures,
which require no special tools other than regular shop wrenches, several
wooden blocks or bricks for propping up the sidecar and the motorcycle,
two straight strips of wood for toe-in measurements, and an angle bracket
for measuring lean-out.
Note: For BMW models a special mounting bracket
may be needed.
Working in a clear area, prop up the frame of the sidecar with blocks
of wood or bricks to hold it level. Open the packaging of the
Universal Mounting Kit and check all parts against those shown in Figure
For safety reasons and for best performance and riding comfort the
sidecar should be attached to the motorcycle and all adjustments
made in accordance with the instructions given in this guide.
Before proceeding, layout the Universal Mounting Kit and remove the Nuts,
Bolts, and Lockwashers from the four U-Clamps, then remove tIle Spacer
Block from Inside each U-Clamp. On the Strut assemblies, remove the
Bolts from the Eyebolts. Have two long straight strips of wood about
eight feet long (such as 2x4's), and an angle bracket, at hand for
toe-in and lean-out measurements later.
Attaching Your Sidecar to Your Motorcycle
Figure 2 indicates the four attachment points on the motorcycle to
which the U-Clamps must be fastened. The four U-Clamps are identical
and consist of the U-Clamp, Spacer Block, Bolts, Lockwashers, and Nuts.
Large and small Shims are provided for use on frame tubes which are
too thin for the U-Clamps. To attach the U-Clamps to the motorcycle
frame, proceed as follows:
- Fit the U-Clamp to the top front of the motorcycle frame, insert
the Spacer Block, and fasten in place with the two Bolts,
Lockwashers, and Nuts.
- Thread the Eyebolt through the
Spacer Block and tighten it against the frame tube. If the
frame tube is too thin for a firm grip, insert the Large
Shim ahead of the Eyebolt. If the U-Clamp is still too loose,
insert the Small Shim at the rear. See figure 3. Tighten
the Eyebolt firmly to hold the U-Clamp in place.
the other three U-Clamps similarly to their attachment points
as indicated in figure 2. It is important to fit the top
U-Clamps as high as possible on the motorcycle frame, and
the bottom U-Clamps as low as possible.
- Note The front bottom U-Clamp may have to be attached to the
cross member of the motorcycle frame in certain cases. See
IMPORTANT: Before attaching any U-Clamp, make sure it is not obstructing
any operating control on the motorcycle, such as levers, rods,
switches, and not rubbing against any wire.
The Curved Bar and the Sliding Clamp are attached to the sidecar
frame as follows:
- First loosen the two holding bolts which are fitted to the front
end of the sidecar frame, then insert the Curved Bar into
the frame. Do not tighten the two holding bolts at this time.
Note that the Curved Bar can be swung in an arc to simplify later
assembly when connecting the Eyebolt of the U-Clamp to the Clevis
Adjusting Bolt of the Curved Bar. In figure 4 one of the two holding
bolts on the sidecar frame is visible, as well as the two Locknuts
on the Clevis Adjusting Bolt.
- Attach the Sliding Clamp to the rear part of the sidecar frame
with Bolts, Lockwashers, and Nuts. Tighten the Bolts
only enough to hold the Sliding Clamp in place at this
- Insert the Eyebolt with the Spacer Sleeve into
the Sliding Clamp, and fasten with Nut, as shown in
figure 5. Figure 6 shows the Eyebolt and Strut inverted
for cases when such an assembly is required.
remove the bottom Nuts from the Eyebolts on the two
long Struts, then insert the Eyebolts into the front
and rear holes provided on the sidecar frame, as shown
in figure 7. At this time reattach the Nuts to the Eyebolts
loosely. Note Do not insert any Cotter Pins at this
time, as the bolts will have to be tightened securely
after toe-in and lean-out adjustments have been completed.
the motorcycle on level ground on its wheels so it stands
upright. This can be done with wooden blocks or bricks
placed under the frame. Position the sidecar at the
right-hand side of the motorcycle so that the distance
from the motorcycle frame edge to the sidecar frame
edge does not exceed 1-2 inches. Prop up the sidecar frame to hold
- IMPORTANT: In final assembly, the short Strut
at the bottom rear of the sidecar frame must be at an exact right
to the sidecar and motorcycle frames, thus placing the
sidecar wheel ahead of the rear wheel of the motorcycle
by 8 to 10 inches. This wheel offset distance is important
(see figure 13).
- Fit the Clevis Adjusting Bolts of the Struts and of the Curved
Bar to the Eyebolts of each U-Clamp, and insert the
Bolts to hold the Struts in place. See figures 8 and
9. During alignment operations these Bolts must be removed
to allow the Clevis Adjusting Bolt to be turned in or
out, as necessary. The Locknuts on all Clevis Adjusting
Bolts are left loose at this time, but will be tightened securely
after Toe-in and lean-out adjustments are completed.
- IMPORTANT: The long Struts connected to the top
U-Clamps on the motorcycle frame must not be parallel to each other.
When viewed from the top, the Struts must be angled outward from
the sidecar frame to the motorcycle frame, as shown
in figure 10. This angling of the Struts provides stability
and lessens stress on the motorcycle and sidecar. From
the standpoint of safety, each Clevis Adjusting Bolt
must be threaded into its Strut at least two inches
- With all Struts connected, remove the supports
from under the sidecar and motorcycle.
Toe-in and Lean-out Adjustments
When riding a motorcycle with a sidecar attached, stability and control
depend on proper Toe-in alignment of the wheels in relation to the
line of travel, and the correct amount of Lean-out of the motorcycle
from the exact vertical.
Under certain conditions it may be advisable to have your dealer
stiffen the front and rear suspension of your motorcycle by installing
air pressure cups or other devices, and inserting cotter pins into
the wheel axles (or using axle locknuts).
Toe-in adjustment is as follows:
- Place one of the long straight strips of wood against the outside
edges of both motorcycle tires, with the front wheel facing
straight ahead. Place the other strip of wood against the
outside edges of the sidecar tire. See figure 11.
the distance between the wood edges at the front and rear.
For accuracy and consistency, take the measurements at one
foot ahead of the front wheel, and one foot behind the rear
wheel. Toe-in difference at the front must be between a 1/2 inch to
3/4 of an inch less than at the rear. See figure 11. If the distance
difference at the front is greater, turn the front top and bottom
Clevis Adjusting Bolts clockwise (tightening). Note The top and bottom
Clevis Adjusting Bolts at the rear may have to be loosened (or tightened,
as the need may be) in order to achieve proper toe-in. Counter-clockwise
turning of the Clevis Adjusting Bolts reduces toe-in.
Lean-out adjustment is as follows:
- Place an angle bracket against the outside edges of the front
wheel tire, as shown in figure 12. Note the clearance between
the tire and the angle bracket at the ground surface. The
correct lean-out distance is 1/8 of an inch.
- If the lean-out
is not correct, remove the Nuts and Bolts from the Clevis
Adjusting Bolts at the upper ends of the front and rear Struts,
then turn the Clevis Adjusting Bolts inward to lessen lean-out,
and outward to increase lean-out.
- After making all adjustments,
replace the Bolts and Nuts into the Clevis Adjusting Bolts,
tighten securely, and insert all Cotter Pins.
- Test ride
the machine, with a passenger in the sidecar. Note that the
weight of a passenger in the sidecar brings the lean-out
adjustment back to zero, which is correct. For this reason
it is suggested that when riding solo an appropriate weight should
be carried in the sidecar for better stability. Ride the machine a
short distance in a straight line and also in circles to both sides.
From the standpoint of safety, bear in mind that when turning to the
right centrifugal force will tend to lift the sidecar wheel off the
ground. At fast speed this is dangerous! After the test ride, check
the Toe-in and Lean-out adjustments, and if necessary make minor changes.
Thereafter, check these adjustments after every 500 miles of travel.
Whenever strong vibrations or shaking are noticed, it means
the Toe-in adjustment is out of line.
- Normal riding stresses and vibrations may loosen the bolts and
nuts. Check all attachment points periodically to ensure
that nothing has loosened!
The sidecar Wheel Offset, Fittings, and Brake must be checked periodically:
- Refer to Section B for information regarding adjustments. See
figures 11, 12, 13, 14 and 15.
- If the sidecar wheel
must be removed, the fittings come off as shown in figure
14 (Cotter Pin not shown). Replace in same order, and
insert Cotter Pin.

Coil Spring, mounted on the Swingarm, are shown in figure
