Only 20k mi. on the '09 and right front fork started leaking. Used the "seal mate" tool and it worked its magic! It wasn't bad dirty but must have been enough crude to cause a leak. Went ahead and cleaned the left fork too. I'm now a bit more alert to keeping the forks clean & dry. This is not a paid advertisment but I'd gladly pay them more for the tool. Got 2 for $9.00 on their ebay site.
