Hi XX, Bees,
Yes, it just blows me away that a company like Honda that builds outstanding drivetrains then puts garbage components in one or two very important areas.
The Goldwing is an expensive bike. The kind of person who buys it would not care about a couple of thousand dollars added to the price to have the suspension and everything top notch quality right from the beginning.
Bean counters upstairs saving pennies who don't know s#$t about riding, driving or auto mechanics.
My 1999 VFR800.....an over engineered, outstanding bike in it's day, with a bulletproof engine, but Honda put crappy suspension,
and worse still a garbage Regulator/Rectifier that is guaranteed to fry itself and take out your battery and stator leaving you stranded somewhere unexpectedly.
Then there is my 2002 CBR600F4i,
a relatively cheap bike with a bulletproof engine, that has everything well done. Fully adjustable suspension front and back that is good enough for an amateur track day.
Dave Moss, the suspension guru recommends changing fork oil
every year, but I guess it depends how much mileage the bike has and how it has been ridden.

You are preaching to the choir! That and ergonomics are the first upgrades that anybody should do instead of bling.
Especially on a two wheeler, your tires and suspension determine your ride and how safely the bike handles. Traxxion & Penske is expensive - YES, but what's a human body and suffering worth. That was my reasoning for having good suspension and buying expensive Motoport gear. Boots too....get the best ankle protection that you can afford. Rabbit foot ankle fractures are not fun.
I'll add to that. Watch some youtube Dave Moss videos at track days. You will really shake your head at the number of people who have high end fast bikes (usually Italian) and clothing to match who have not bothered to do a single adjustment to the suspension and foot and hand controls to suit them, and yet they want to do a track day. The modern attitude inspired by manufacturers....Fashion (Looks) over Function! SHEESH!
Great that you have held on to your vintage Wings.
Cheers, and end of rant,
Ross
