<div class='quotetop'>QUOTE (richo @ Sep 2 2006, 03:15 AM) <{POST_SNAPBACK}><div class='quotemain'>250s are a dying breed, and I`ve heard they were going to replace them with 600cc 4 strokes, the main reason being that so many domestic series organisers are dropping thier 250 championships in favour of Supersport championships, but 125GP bikes still have a strong base in domestic championships, so I think they`ve still got some life in them. And I heard they would replace 125s with 400cc four strokes... That`s a lot of grunt considering how young and unexperienced some of those riders are, how much power could the squeeze out of a 400 prototype? must be in the vicinity of 100-120. That`s a lot of grunt for a 15 year old with limited experience. If they gotta change the smaller classes to 4 strokes I think it should be 200cc bikes instead of 125s and 400cc bikes instead of 250s. Just because a lot of 125 and 250 riders dont have the experience that MotoGP riders do, and they could really hurt themselves on big-power four strokes.You are joking Richo, hurt themselves? The days of 250's are numbered. The support classes will go 4stroke eventually but as to what capacity nobody really knows and it's a long way away. Big problem is that 250's and 125's are cheap. !25 racing is here to stay for a while yet but as to what 250's will be replaced with I haven't a clue. I reckon a 400 could put out 140+bhp, considering a 250 puts out 105+
