C Casper250 Motosapien Dec 12, 2000 579 1 Aug 31, 2004 #1 I remember seeing one in a magazine comparing a 125 to a 250f. Was wondering if anyone has seen one of a 250 vs 450f?

C Casper250 Motosapien Dec 12, 2000 579 1 Sep 1, 2004 Thread starter #4 Thats what I was looking for. From looking that the FMF dyno runs, is it true that the 250 2t makes less peak HP then a 450 4s? I thought the 250 2s was closer to the power output of a 450 4s then the 125 is to the 250f.

Off topic, but geeez... that write-up was a joke. They didn't have anything good to say about the 125... it's like they have stock in the 4 strokes.
