I reckon the last 125mxer will be 06 for the 07season, though it may be sooner depending on sales and whether or not they all have a good 250f. The die was cast as soon as the sanctioning bodies allowed Fs the unfair capacity advantage of double capacity, when to be fair it should about 66% larger, not 100%. I think the powers that be ( manufactures etc ) decided that we should all ride 4s, and the goalposts will be moved to a position which ensures that.
Its widely believed that the MX world champ tracks were made more open and less technical last year to better suit 4 stroke power.
The same has happened in GP, where the 500cc smokers were asked to compete with 1000cc , and predictably enough couldn't and we end up with big H top of the heap again, though the others may catch up sometime.
As for which is best for MX I agree with one or two others in this thread that the 4s is probably faster over a moto for most because it is less tiring to keep up a good lap time. An ex Brit champ told me that a CRF450 was worth 3 - 4 seconds a lap for him, so I reckon for me it would be more like 10 secs !
However, I still like my 2000 Suzuki, and if changing would have a tough decision between 2004 RM250, or a 4 stroke. If there was a 375cc four stroke in a 125 frame the choice would be easier. Anyhow, its irrelevant cos I can't afford to change anyway, so the 250 and I will just grow old gracefully together, until we make like the dinosaur.
