Hello, Im from Portugal, I´m looking to buy a used YZ450 (and affordable) 450, and I´m deciding between wich of these you would go for... Both are selling for same price, so its only about the bikes...one is from 2005 and other 2004 but with a few extras..any big diferencs beteen these years? YZ450F 1: Year: 2005 Road legal but needs lights and plate. Pretty much stock as it seems.... Check the 2 pics YZ450F 2: Year: 2004 One year earlier model, but already has lights and plate, exaust (anyone know what it is?), and a few more little extras... Check the 5 pics I want to set the bike mainly for trail riding in the woods. Please help me at making the best choice...let me know your what your think... Thank you!!
