Yamaha completely redesigned the YZ250 for 2005, so for 2007 they just made some minor chassis updates (including revised Kayaba 48mm forks). That may not matter in this case, as this bike has spent the last 16 years in the original delivery crate, and one assumes that it will stay that way for the next collector owner.
There isn’t much to say about this example (VIN: YZ250N11256960101) as it’s still in the original crate.
Find this YZ250 for sale in Elmhurst, Illinois with bidding up to $5,500 (and it looks like the reserve has been met) here on eBay.
Interestingly, the seller also has a crated 2012 Honda CBR250R for sale as well – you can find it here on eBay.
