Paul’s Kawasaki ZZR600 Leaner Sidecar

“In the photo of the bike leaning out I don’t think I would lean out that far when cornering (but it would come close to it) and even if I’m trying to I have never hit the car with the bike on a left hand corner. I wouldn’t want the car any closer to the bike, it seems about right.” Paul

Tow Bar Rear Mount – Discussion

I was wondering what Haul N Ride readers think of using the tow hitch for a rear mount motorcycle attachment for a Leaner Sidecar.

Option 1. A Tow Ball could provide a great mounting point for bikes with an exhaust clearance issue.

If you would like the sidecar rear mount inline with the centre line of the bike, a swivel hitch attached to the tow ball would allow perfect exhaust clearance during lean.

Using Option 1, the tow ball, could help in countries where sidecar attachment is on the same side as the exhaust, and leaning towards the tub is limited by the location of the exhaust pipes.

My thought is that the tow ball will rise over the speed hump or kerb lifting the sidecar rear mount. Whereas the rear mount located underneath the motorcycle belly will scrape on the obstacle.

Option 2. Mount Off-centre and attach to the Tow Hitch.

John’s Leaner is an example of the sidecar Front and Rear Mounts, mounted off-centre to the centre line of the motorcycle.

John’s Leaner Sidecar Combination – Homemade Project

Notice in the photo of my Honda Shadow below, the Tow Hitch would provide a great Rear Mount Attachment location below the exhaust (off centre of the centre line of the bike).

Here are the Ground Clearance Measurements of the Honda Shadow Tow Hitch Square Tubing to demonstrate my example.

Please comment below with your opinion on Option 1. Tow Ball Swivel and Option 2. Tow Hitch Off-centre Attachment. Dave


What Ground Clearance would be considered the minimum clearance before making contact with Kerbs (Curbs) and Speed Humps?

Ground Clearance of my Rigid Wheelchair Accessible Sidecar FJ1200 is a great example.

My Rigid Sidecar has a low ground clearance due to the rusty motorcycle exhaust.

The exhaust does scrape on some speed bumps and Kerbs (Curbs) so here are the measurements as a guide.

It would be nice to collect specs of your designs

Here are some ideas.


  • Rear mount ground clearance measurement
  • Front Mount Ground Clearance measurement
  • Bike make/model
  • Make/Model of Sidecar Tub
  • Tandem or Single Tub
  • Total Width of Combination lean in
  • Total Width of Combination lean out
  • Distance between sidecar and bike
  • Sidecar Tire (tyre) Speed, Weight Rating
  • Sidecar Rim details, diameter, rim width
  • Shock Absorber/Swing arm type on sidecar wheel
  • Frame type, eg square/round tubing, fibreglass tub, aluminum (aluminium) frame, steel sheet wrapped etc
  • Pivot Attachment to Motorcycle, (bush, heim joint etc):
  • Motorcycle Sub-chassis details (Square/Round Steel Tubing, Aluminum etc) and attachment to motorcycle (High Tensile steel, lock nuts etc):
  • Sidecar brake details if fitted, drum/disc, plumbed to motorcycle rear or front brake cylinder

What is it like to own a Leaner:

  • What is it like to ride a leaner in comparison to a rigid sidecar combo?
  • What is it like to ride a leaner in comparison to a solo bike?
  • Does the sidecar try to overtake your bike when slowing down with a passenger?
  • Does it fall behind you if you accelerate fast?
  • Do you need to adjust the tow-in when changing from passenger to empty?
  • Do you remove the leaner and ride as a solo?
  • Have you removed an indicator from the rear of the motorcycle to avoid confusion for other road users?

The more information, photos and drawings we collect, the better we can help other builders with their project and design.

  1. Hi Dave,
    Starting my first leaner project. I have an R1200C BMW and an old sidecar
    I found on a marketplace site. I have no Idea what I purchased. I haven’t
    been able to find any information anywhere. it’s wedge shaped, very low in the front and looks like it will have great clearance for a leaner. I don’t see a place to insert a picture on here but I e-mailed you one. I sure would like to find out
    what I purchased.
    Thanks Larry Shaw

    1. Hi Larry,
      I will be happy to add your photo to this page to enable someone that may be able to identify it for you.
      As you build your leaner project, I encourage you to email the details and photos so we can share the journey with you.
      Have a great day. Dave

  2. Great site thank you. I am researching and wanting to turn my 1978 Goldwing GL1000 into a leaner. Has anyone here used an early Goldwing that can share information and pictures of the subframe design?

    1. Hi Tory, Goldwing should be a great project as they are tall and should provide better clearance between the handlebars and tub. Good luck, hopefully someone visiting Haul N Ride, has some pics for you. I look forward to you providing Haul N ride pics of your bike as you build your project 🙂

      Have a great day. Dave

  3. I am in the design stage of a “leaner” … currently working on the suspension …

    I need to know what everyone has been using for a spring loaded shock … recommendations for travel … weight load etc.

    Thanks for your input … Red

    1. Hi Red,
      It seems the majority of sidecars use a swingarm with a shocky suspension.
      The other option used is torsion independent suspension.
      Hopefully other builders will comment and help you find the information you require.
      Here are some ideas that may help.

      A visit to the following site will provide 4 pages of homemade examples.

      Velorex sidecars: The fat 20mm (13/16″) axle is supported by an adjustable hydraulic shock absorber mounted on a swing-arm for smooth and comfortable riding.

      Watsonian Squire sidecars: It sits on a tubular steel chassis, which is uprated from the 1940’s design with addition of a shock-absorber and 16″ wheel.

      Trans Moto Sidecars: use a gas shock

      Cozy Sidecar Shock:

      DMC Sidecars: Full Swing Arm Suspension with a Hagon shock

      Steve’s Workshop: Scroll down to suspension.

      Ural Sidecars: Rear suspension: Double sided swinging arm with gas shock absorbers
      Sidecar suspension: Single sided swinging arm with gas shock absorbers

      Good luck and thanks for visiting Haul N Ride.

      Ride Safe, Dave

  4. Hi,

    I have just come across your site and the explanation on leaner sidecars is great!
    I would like to show my leaner project based on a Velorex sidecar for my Moto Guzzi California 1100 Ev. I could explain the issues I encountered, and provide some pictures.

    1. Hi René,I would be delighted to create a post on Haul N Ride outlining your Leaner Sidecar Project.
      If you would like to write a story of your build, sharing the issues you encountered and some photos, please send to
      Thank you for your willingness to share your journey with other motorcycle enthusiasts, we look forward to learning more about your ride and be encouraged how you overcame obstacles along the way.

      1. Hi,

        I’m sending some info on my Velorex with custom chassis on California
        It all started with a second-hand Velorex sidecar.
        This had a standard chassis, which did not have required strength and stability for the heavy Guzzi.
        I ended up replacing the standard chassis with new tubular frame, but kept the suspension, axl and wheel. I also kept the lamps and wiring. My dad and myself created a subchassis for the guzzi. This chassis is mounted using the central stand mounting points and the engine mounting points. The guzzi has a strong Tonti chassis to allow all this extra load without issues. This sub-chassis provides 2 centered pivots, which allows the bike to pivot independently from the sidecar.
        However, the lean angle was very limited because of 2 factors: the low exhaust pipe at the right hand and the 18 inch Harley wheel and tire, lifting the sidecar.
        I also noticed some interference between the bike’s handlebars and the sidecar’s windshield when leaning to the right….

        At some point I decided to revert to the classic 4-point sidecar, by adding clamps and 2 extra bars.
        However, this requires driving skills which are completely different than riding a motorcycle. For example, pushing on the right handlebar makes the motorcycle turn right, but makes a sidecar turn left…

        At first I enjoyed the learning process.
        And I enjoyed some nice little trips with my wife and the dog.
        Speed signs were always respected, since the combination could only turn slowly 😉
        What frightened me, was the emergency stop: the sidecar pushes the bike to turn to the left, so you may end up on the wrong side of the road…
        After a few more dangerous situations on the road, I sold the sidecar ….to buy another sidecar!
        You can read more about it elsewhere in this site 😉

    2. Thanks for sharing your project with Haul N Ride René.
      Ride Safe!

  5. Hi Dave,
    I’ve been reading your page with a lot of interest. Thanks!
    I’ve build my first leaner sidecar 6 years ago after reading about it. I’d never seen a leaner sidecar in real life at that time but that didn’t stop me.
    At first I build a prototype attached to an old Suzi GSX1100 from ’83. This was a very rough build but it served my purpose; I learned a lot on how to build my next one.
    I’ve attached the second build to my BMW K100rs from “88. The tub is a Polish Junak tub. The total weight is under 60 kg.
    The combination is proving to be very reliable and an absolute joy to ride. I’m riding it a lot together with my daughters and they love it.
    I’ve made a small build topic on ADVrider with a little bit more info ( ), if you are interested in posting my hack on your site, you are very welcome to do so. I’ve got a lot of pictures and I like to discuss with other leaner owners.
    Best regards from the Netherlands

    Reinier Smallegange

    1. Hi Reinier,
      Thank you for visiting Haul N Ride and providing your comment.
      I visited the ADVrider link you shared in your comment and love your creativity.

      How clever that you used the Citreon swingarm and Suzuki shocky from spare parts in your garage.
      However, the square tubing swingarm looks a lot neater and simpler.

      With the front mount connected higher on the bike, as the bike leans, it will naturally steer the sidecar instead of scrub the tire.
      Question: Is this what you have found?

      Apart from the ships boulder bending the sidecar frame, have you had any clearance issues?
      Question: What is the clearance between your frame and the road?

      Relocating the swingarm seems to have put the sidecar wheel hub further to the rear and improved the right turns.
      Question: Could you share with our readers the “Wheel Lead”? (distance between motorcycle rear axle and Sidecar hub center).

      Question: Could you please let us know the total width of the combination without lean and total width on full lean?

      Under 60 kgs is a great sidecar for a leaner combination, so light.

      We welcome you email photos and explanations of you build to
