Talking 1975 Sportster XLCH

Hey Guys just wonder if any one has put a wider front end on an older sportster? If so what company did you use and do you think is the best? Also do you know and companies that make a replacement swing arm for the frame, just a little wider? I dont want to go to much wider but would like to get a little more mm in there. In advance thanks for any answers given they are all very appericated.

Life is a short ride, to an unknown place. Where it all ends I dont know and dont care. I am just enjoying the RIDE.

On a 1975 Sporty, you're going to be limited with options due to age and frame style. Wider tires are hard to fit due to narrow fender mounting/clearence. I know guys that spaced the fender rails out, and used a wider rear fender, cut to fit, to make it work, however, the chain will limit your tire width, as with a drum rear brake, you can't shim anything out. Not sure if you can upgrade to a square swingarm and rear disc brakes.

The steering stem diameter for your bike is 7/8", and not the 1" like the newer harleys. You can get conversion cups to make a wideglide fork fit here:

The other alternative would be to look for an old Sevi-Car springer fork, (OEM) which had a 7/8" stem.

You can also look at WG conversion kits, but your fork legs are 35mm, and not 39mm, as the kits are made for. The 39mm (1987 and newer) fork legs are relatively cheap, as well if you get them used and want to go that route, as the 35mm legs look kinda skinny in a wideglide set up....

If you can put your finger in between each side of your rear fender and got a little sidewall chain clearance you go up a tyre size.

I would check V-Twin Manufacturing - Aftermarket Products for Harley Davidson and Antique Motorcycle Parts, they have alot of older Sporty stuff available. Maybe they will have something.

to upgrade the front end you may just have to change your neck cups, bearings, etc.

billitwerx.com has a good set of cups

If I remember correctly, that year had ball bearing neck cups, and you could update to Timken bearing neck cups and have alot more choices, IF I AM RIGHT.

Yes you're right. However, in order to install a wide glide front end, like the original poster wants, you need to change the cups/bearings to 1", as nobody makes a wide glide kit anymore, (rarely if at all) that's a 7/8" steering stem, as it's not been used for decades.

The TYPE of bearing isn;t the issue, it's the steering stem diameter and length. The likelihood is there as well the stem will have to be cut down and threaded too.

the billit works cups are taller (thicker) and once installed, a standard length 1inch stem will work with the ironhead frame
