Did mine over Christmas. They were in good condition with plenty of grease in . Gave them a clean and topped up with grease done at 16,000 dryish miles
Easy enough job Mark? What grease do you use with them? There were horror stories with them napping on the Aprilias If they weren't serviced.
Probably not , I've put 10,000 miles on it in the last 4 years and this the first time I've checked it
