I just spent some money to add complete Enzo suspension, Top end, new cam to my almost 3 year old 450. I was considering a 2005 new bike - but did not feel like there was any real advantage to this. After my first ride on the "new" bike and I can tell you I am completely happy with my investment. The bike simply is not the same machine...It has relit my enthusiasm for riding and racing as I was becoming very bored and lithargic on my "old" 450. Enzo is the best suspension system for this 03 blue bike - I was jumping things I could only dream about. My confidence is very high - the plushness over braking bumps and hard landings is incredible - I should have done this a long time ago! It is well worth the $. The cam I had installed came from the same folks that do Kyle Lewis's Hondas....now my bike just pulls and pulls and pulls like a freight train....so much better than stock! The bottom line is this : My bike is completely set up for me and my riding style. It turns incredible now with the new suspension and the existing Storm Link - much better than ever before. My confidence with this "new" ride is unbelievable and I am extremely happy that I did not purchase a 05 to find that I would have to dump a ton of money in it to make it right!
