So it starts. I have decided to mount a sidecar on a 2015 XG Street. I have measured things up and don't see it being that big a deal.
Raked tree is some thing I will decide on after I test it. I will be looking at maybe using a Street Rod tree.
Steering stabilizer will like be added
The side car will be a Vilorex 563. With windshield removed.
Most like will be winter work , however if time allows I will star on it sooner.

I'm looking forward to your reports on this. The more I learn about sidecars the more I want one for late and early season riding, although that's going to be a year or two down the road.
After the initial installation is it difficult or time consuming to take the sidecar off and reinstall?
What draws you to the Velorex 563 as opposed to the slightly lighter 562?


On another thread you mentioned the 563 has a slightly larger wheel. What is the significance of that? Is that desireable due to reduced rolling resistance? Maybe it makes for easier alignment with the tug?

If can make a difference in mounting the sidecare if heights are closer it is easier. I will likely make some changes . The 563 has a spoke wheel .
I should be able to fit a bearing to a XG rim that will allow me to use an XG front wheel.
Height of the tire has no impact on roll . Width does and side does not need a wide wheel. As I go through this I will try to past on experiences and what I have learned about them.
On my fatboy I did not need a raked tree the street stabilizer work fine. I am hoping for the same results with the XG.
This is the bike it will be matted to. 2015 XG750 with 600 miles on it. In a few weeks I will get it in the bike room and start figuring out the mount points.

The sidecar it dusty but that will wipe off. Thinking about fitting an XG wheel to replace the spokes. Working on a couple different approaches for mounting . It will also get a flat black paint job to match bike. Granddaughter wants pink.

Looking forward to seeing the finished product. This is an idea I've been toying with myself.
Sidecar have there own leaning curve. The do require building so new inherent riding skills. But nothing most can not do. They are not a car and they are not a motorcycle.
As for mounting I think most with some mechanical skills can get it done. You get it as close as you can to instructions then work on fine tuning it.
As this goes along I will try to cover that and explain why I am doing some of what I do.
I want to keep stock exhaust on it. It should be out of the way and no need for a loud pipe blowing the riders ears out.
The 2015 XG750 has an interesting rake to the front end. I am planning to try a steering stabilizer first and avoid a raked tree.

Hoping this weekend to lay out lines on the floor to measure off of. The side car wheel needs to be ahead of the center of the bikes rear wheel. The sidecar will need about a 3/4 inch toe in and the bike a 1 degree chant toward side car. Having good lines to measure off of makes it a lot easier.
This is a project that if time was important , it could be done in a day but lot going on right now. Also I have a 9 year old grandson that will be helping so need to work around when he will be here.
Been kind of lazy this summer bike room is a mess. Stuff needs to be moved around to make room.

For those taking notes:
The 1 degree chant is so that when you get on the bike it returns to straight up. One of the things you may tweak a bit once everything is mounted up.
Without the sidecar wheel being properly ahead of the bike rear wheel you would not be able to turn.
Toe is something you may very well adjust a little also .

Any thoughts on gearing smitty? I seem to remember old Brit sidecar tugs mainly ran with a 19 tooth gearbox sprocket rather than the usual 21.

Still trying to remember the sidecar law of cornering, left hand bends you ride around the chair, and on right handers you throttle off, and let the chair ride around you. That's in England anyway. Other way around for you guys who ride on the wrong side of the road.

Older bikes were grossly under powered. With modern machine gearing is fine . With a six speed or a 5 speed if you need to just drop a gear you will still be going fast enough to get a ticket.
The sidecar I am mounting to the XG750 is commonly mounted on older BMW with far less power. It is also mount on to older Sportster's.
As we go along with the install we can get into to tail and the front end.
I have one mounted on a 1996 Fatboy Harley EVO. It has been on it 3 years now. That bike was never confused with an over powered bike. It has a 5 speed . Even when I need to drop to 4th it will run 70 plus and will run at 65 Mph all day long if need be.
About the only time I need to use 4th is a long steel grade, or a very strong head wind. Sidecar windshield on or off makes a big difference.

This is a good read for you

Been busy getting some rides in. Couple great road trips another 700-800 mile one next weekend. 4,500 miles last few weeks. Plan is to wait until weather bring riding to a stand still. Then move the Street into bike room and get started on the side car it is sitting here waiting to go.

Lately I've been watching some YouTube reviews of Urals. The lineage of these goes back to the Soviets reverse engineering some late 1930's BMW motorcycles. I was surprised to find out that the modern Ural is also a 750cc engine making 10 horsepower less than the xg750. They also have 4 gears instead of our 6. I don't know the gear ratios for either bike, but our bikes would appear to have a leg up. OK, so the wheel of the car won't be driven, but I can deal with that.

Power to the sidecar wheel is unnecessary. Worst case you would down shift one gear . I have a side car on a 1996 FB Harley it is a 1340 engine and by any standard under powered. It works just fine gear as it comes from the factory.
When you have a side car you do not go out and try to run 100 MPH nor race every one fro a traffic light . Different style of riding.

Well, there goes my plan to take my bike to eastern Europe and head off road across the steppes in winter. My understanding is that a driven wheel on the car is actually quite unusual, so no, it's not a disappointment.

The guy that does the MC Commute videos for Motorcyclist magazine didn't even want to take his Ural out on the freeway at 70 mph. He said the bike could do that, but without a bit more power the trip wouldn't be fun. Again, that's a 48 HP bike with what would appear to be a much heavier sidecar.

I have at time ran mine 80mph, run it 65-70 MPH often if need be. Mine is considerably heavier than a Ural.
I want to get going on putting one on the Street stuff is laying there . I just am not going to waste the fading good weather working on one when I can ride.
This is my 1996 FB with one on it. Yes I go a little off road with it.

Back on the sidecar mount. Been busy with other hobby. I have found a company that makes a mounting kit for the XG750 that may save a lot of fab work. I have requested more information from them, Want to see what they have come up with.

Sidecar and bike are in the bike room. That is step one to start the install. Need to move a few things around. Lay out some lines on the floor. Line the bike and side car up and figure out if I am making my own mounts or buying some from DMC that will give me a head start. What DMC offers is not a simple bolt on but some of the work is done for you.
