We still have one ( I'm not sure what year it is, it's purple and white)
It still runs great.
Our bike had a stack of three seals in each leg. And I had to replace them at least twice a year, sometimes more.
It was so bad I had extra sets of seals. It's was very upsetting to fix them, ride for an hour, and have them start leaking again.
But we fixed that problem.
I took the lowest seal in the stack, trimmed the lip so it wouldn't contact the leg, I used that as a spacer,
So the second seal would set in the leg right.
The next one up I used a seal from a KTM fork ( I can't remember the part number )
But it was the same size as the Aprilia seal, but much more pliable.
The third seal ( the top one ) I threw away and used a wiper from a 94 Aprilia.
The next tip came from Mike at the Trials Shop.
Put the front wheel on then "cycle" the forks a few times.
With the forks compressed, clamp the axle down. This keeps everything centered.
After I used this setup, I can't remember the last time I had to replace them.
