[QUOTE="Badgas, post: 256481, member: 24441"] I took a Dick Berleson riding class about 3 weeks ago. Gary Hazel, the owner of Thumper Racing, had a 450 there he was riding. They just got finished doing a Dirt Bike Mag test on their 450 kit and their YZF 280 or 290 kit. I didn't get a chance to ride it, but with gary riding it it ran like bat out of hell. He said it's not much less HP than a 520. Also he said likes it better because it's short stroke engine. Which makes the bike feel lighter. Less reciprocating (sp?) mass. KTM's new 450 is going to be a 450 long stroke. I don't know what month the mag test is going to be out. Give Gary a call. Super nice guy. Gas :cool: [/QUOTE]
