that is not the full picture Eamonn. The Earles front endsI have seen on a GL1500 have a 38mm stem diameter. I think the GL1500 has a 42mm diameter and the one I seen an adapter had made to make the steering tube smaller in the diameter to the Earles accept. This is I believe a common way to adapt the Earles to other machines.I asked a BMW owner about this. Hes well up on the tech side as he repairs them etc. He says no, can't be done.
...and used ones don't crop up too often either.check out the united sidecar association site. there are leading link earles (front end will rise not dive when braking)... and a "conversion kit" from eml, but it is for sidecar bikes only and very pricey.... the leading link earles I believe are in the $2,000 range
You'll need a complete standard 1500 fork setup to go back on the bike. Selling the sidecar complete with all it's mounting hardware will more than pay for a new setup for the front end. Once you get the swap done then you can sell the Earles Fork front end for a good price.Good afternoon Gentlemen. My husband owns a 1989 Goldwing 1500 Interstate and when he bought it, it had a 1991 EML GT3 Sidecar attached. It has Earles Forks on the front to help with the sidecar handling. He wants to take it back to a two wheeler and was trying to figure out whether he would have to replace the Earles forks with standard Goldwing forks or if he could leave the Earles on? Any help or ideas would be appreciated.
