I'm a Honda guy, however, I have always dug the Yammies too. I'm thinking of getting a 2003 or 2004 450 because they were supposed to be so gnarly. I have seen some old dyno charts in the mags and yes, I know that dynos do vary from one to another. It looks like the bike was pumping out about 47 to 49 HP which is less than my 2007 CRF 450 AND THE 2006-2007 yz 450. I have never rode on of those beast, so I can only assume that it just had a crazy shot of torque from the bottom to the top? So who here has rode the Hondas the Yammies and even that 2007 Kawi 450 that was supposed to be a monster? If you could give a seat of the pants description, that would be great. I was running a Service Honda CR 500 2 somkie back in 2004 and it was just one big heap of torque for about 2 seconds and then you shifted. My CRF 450 would beat in a drag race everytime once it was in 3 rd gear and singing in that killer mid range. I would bet that the 2003 YZF 450 would destroy it? Thanks for the input.
