I've been one to keep my bikes, this year i sold both my 04 Tazer and my 05 DHR (saddest moment of my life). On the way are an Operator and a Tanuki DL as replacements. I plan on keeping them for a season or 2 and selling while prices are still high. the difference will be a "rental fee". then you never have a bike thats out of date and your not dumping endless cash for a bike that will never return its value
