Front Wheel

Does anyone know of a wider front BMW wheel that I could mount on a leading link for my R100GSPD. I am about to have Lowell Neff build me a front end for my hack but I would really like to have a larger (wider) front wheel. My standard 21 inch rim will not hold a wide tire so I am looking for options. I would need to find out soon cause Lowell says he will be working on my leading link next. Thanks fellas, Tony

cool!

Pics of the hack and build please! Great sounding project.

(sorry, can't answer your rim question...)

Question

Seems you should be able to use whatever you want. I mean, if the whole front suspension is new, Why couldn't you just use whatever the builder recommends?

For a hack I've seen modified car rims with the centers removed and dimpled for spokes. That way they'll accept the smallest VW Bug tires, which sounds like the way to go when you consider how little ilfe you get out of expensive side car tires.

Other than that, there's the 1100 and 1150 series bikes with wires, though you're looking at 18" or 19" rather than 21".

Woodys Wheel works can build anything you want on the GS hub.
Go to the Vendors forum and ask - he replies quickly.

I dont tjhnk any OEM BMW wheel is built to take the stresses of a chair - they would all need respoked anyway so just build what you want.

Thanks guys for the ideas, I will post some pictures as soon as my son shows me how. As far as the car tire goes, I would really like to keep the knobbies.

Most guys when building a sidecar put the same wheel/tire combination on all wheels. That way one spare can go on any wheel.

Woody could certainly build the wheels for you. Last week I think I saw a couple of GS sidehacks at:
http://www.perrysmotorcycles.com/

You might consult them.

BTW - Perry had a offroad K/EML sidehack that he has crossed the Sierra Madre on several times. He could probably give you the best advise on what works well for an offroad tire setup.

Lowell has also made some custom wheels which allow you to run car tires. Have you talked to him about this?

I figure the best I can do is duplicate the sidecar tire/wheel with the front or rear on the bike. I mean...the back wheel bolts on and the front has an axle...so either way that means two spares. I just would like a bit more "contact patch" then the 90/90 gives.

The last bike that I can recall that had interchangeable wheels as stock was my dads old side valve 16 H Norton ,which had QD wheels front and rear - that is , the brake drum (and sprocket) remained bolted to the suspension and the wheel hub was unbolted from the side of the drum .
My dads outfit had the same wheel on the chair, and a spare wheel on the back of the chair.

Heavier spokes for sidecar use were a factory option those days , and sidecar spec bikes with stiffer suspenion , heavy spokes , lower gearing and, where needed, RH exhausts , were availible to order too.
The QD feature remained on Norton rear wheels till the end - that is what the three holes on the Norton rear hub are for.

On a chain drive bike building a front wheel on a rear hub isnt a major engineering problem , but some real tricky engineering would be needed to get a front set up to take a BMW shaft drive rear wheel.
