The Sidecar now has a 750 Street 15 inch rear wheel on it. Solo750 and I cut a fitted axle today. We made several test rides all went well. Pictures will be coming.
Fitted the axle and welded what needed welding today. Test road the heck out of . Took it off rad tried to break it. It works. Pictures to follow.
As of now the sidecar has a factory motorcycle tire on it. Will be ordering the car tire for it. next step will be check the fit to the bike . I am sure a little adjustment will be needed.
Mounting a sidecar on a 750 Street started off as A wonder if it would work . It did, then it was assumed it would really only be for short back road rides for Payton.
That proved wrong. The rig preformed well and with a few adjustment it was doing just fine at highway speeds. And at times it has operated well above legal speeds.
The Rig attracted the attention of another that wanted to do the same thing. The education process of helping him figure out what he was getting into formed a friendship.
His rig works well and he is enjoying it. The desire to make things better has driven us to a car tire on the motorcycle of both rigs , that has worked very well . The next logical step was to increase sidecar tire life. Why not use the same car tire as the rear of the bike ? The reason was simple no 16 wheels that would fit and except a car tire. Most were to narrow. To work right the wheel need to be a 15 inch. Seemed the stock 750 Street wheel would be prefect if the hub was not so wide. You see the results, cut it down. Of course we had no way of knowing if it would work. The factory Sidecar axle was a 20mm and way to short. The answers after some research prove to be using a 25MM that would fit the HD bearings. That led us to cutting a factory HD Street 750 axle to the length we need. While it took some cutting , making new bushing and welding.
The work was surprisingly easy.
The next step is making a hub to cover the axle bolt. We have some ideas that should look like it belongs that way.
Street 750 factory tire is a 140/75R15. The car tire we found to be a prefect replacement on the Wheel is a 155/60R15. The 155/60R15 is a Smart Car tire. Speed and weight ratings are just right for the rig.
Step outside the box. Even if you run into some road blocks. The challenge of doing something different is well worth the rewards.
Not this year but maybe next project for a 750 Street Trike it and stick a wide Glide front end on it. And the answer is no I don't do drugs, just a mind that is wired different.
