I wasn't sure of exactly where to put this, so I ended up here.
I replaced the shock linkage bearings and bushings in my Tuono. The seals appeared to be in good shape and I was going to re-use them. No surprise then when I managed to bugger up 2 as I removed them.
After a fruitless call to the dealer where I purchased the bike (they don't keep any Aprilia parts on hand and now appear to have lost the brand) I tried a few other dealerships. Nobody kept anything like it in stock.
I called Wriason Seals. The fellow on the phone said bring it down and he would take a look. Forty minutes and $19 later I had 4 new metric sized seals to complete the job.
So if you are in need, these guys were able to provide me the parts to get back on the road without waiting another week or so for parts to arrive.
