Vic just replaced mine @ 4 years 10 month's after purchase date. I paid $50.00 for the deductible on the 5 year warranty I purchased with the bike. I have 36000 miles on the bike my only complaint was I noticed the slight oil drip (very minor) in September and it took 3 months to get the replacement. I continued to ride the bike and no major change in the way the bike handled. I did notice that as the temperature dropped it quite leaving the drop or two of oil under the bike.
