Sidecar for a Harley
Installing a sidecar on a Harley-Davidson motorcycle transforms your cruiser or touring bike into a stable 3-wheeled rig, allowing you to carry a passenger, pets, or extra long-distance luggage with vintage American styling.
Harley-Davidson Sidecar Models and Mounting Systems
Whether matching an iconic factory Harley TLE sidecar or modern fiberglass units from California Sidecar and Hannigan, proper chassis triangulation is critical.
| Sidecar Make / Model | Compatible Harley Chassis | Suspension & Brake Setup | Price Range (New / Used) |
|---|---|---|---|
| OEM Harley-Davidson TLE / Ultra Sidecar | FLH / FLT Touring (Electra Glide, Road King) | Torsion bar & disc brake linked to rear pedal | $4,000 - $7,500 (Used Market) |

How to Align a Harley Sidecar in 4 Steps
Follow these geometric alignment steps to set toe-in, lean-out, and wheel lead.
Step 1: Set Wheel Lead at 8 to 12 Inches
Position the sidecar axle 8 to 12 inches ahead of the motorcycle rear axle centerline.
Step 2: Set Toe-In Between 1/2 and 3/4 Inch
Use straight edges alongside wheels to angle the sidecar wheel slightly inward toward the front tire.
Step 3: Adjust Motorcycle Lean-Out to 1 to 2 Degrees
Adjust upper strut turnbuckles so the bike leans slightly away from the sidecar to compensate for road crown.
Step 4: Install a Steering Damper
Mount a hydraulic steering stabilizer between front forks and frame to eliminate low-speed handlebar wobble.
Frequently Asked Questions (7 Questions Answered)
Q1: Does Harley-Davidson still make factory sidecars?
No. Harley-Davidson officially discontinued factory production of the TLE sidecar line in 2011, though top aftermarket companies like Hannigan, DMC, and Champion produce custom Harley-compatible rigs.
Q2: How fast can you ride a Harley with a sidecar?
A properly balanced touring Harley sidecar rig cruises comfortably at 65 to 75 MPH on interstate highways.
Q3: How does driving a motorcycle sidecar differ from riding solo?
A sidecar rig does not lean into turns. You steer with direct handlebar push-pull force, throttle through right turns, and brake gently through left turns to manage weight transfer.
Q4: Do you need a special motorcycle license for a sidecar?
In most U.S. states, operating a sidecar requires a standard Class M motorcycle endorsement or a specialized 3-wheel motorcycle endorsement.
Q5: Can you detach a sidecar and ride solo easily?
While quick-release subframe mounting kits exist, detaching and re-aligning a sidecar typically takes 30 to 60 minutes and requires re-checking alignment specs.
Q6: Why do sidecar rigs pull to the right on acceleration?
Because the sidecar adds unsprung mass on the right side, engine acceleration naturally pushes the bike forward while the sidecar lags, creating a slight rightward yaw.
Q7: Can a Sportster pull a sidecar?
Yes. A 1200cc Harley Sportster handles a lightweight fiberglass sidecar (under 180 lbs) well, though heavy steel touring sidecars require a Big Twin FLH frame.
