Here in the UK we have seen the tide turn, its slow but there are more 2st's being ridden, or it just maybe less 4st's out there ? Our local practice track get's a full mix of riders as its rough and virtually all weather, this year alone the split on any day will be 50/50, 3 years ago it would of been only 20% 2st. Thing is, the oldest 4st seen last week was a 2005 450f, the oldest 2sts thats there everyweek is a 1996 250, yea there are older bikes now and then, but where are all the 1997>2004 4sts ? There's a growing market here for late 4st rolling chassis for 2st projects, I myself bought a 2008 250f roller for £500 and put a 2004 sx200 motor into it, infact its now got a 2002 125 motor in there.
You are right about kids wanting to race 4sts as their easy, but thats a rule drawn up by faceless profiteerers, give us equal dissplacements and lets see how many cam lovers drop their valves for premix. Our schoolboy series have a few 150f's but major on the sx85, at club level where kids are not blessed with ability you may see a few more 4sts, We are all hoping we take the stance of the rest of Europe and exclude the 150 from competition until a rider is 16yo, keeping kids on a max 125cc
We have 3 different National 2st series to race at, and they get attention from big sponsors the press and spectators, as long as we keep buying 2st equipment, it will be made as its a big (and getting bigger) part of our dirtbike bussiness. To big to let go I'd say !
At the end of the day its riders that make the choice what gets made and sold, Honda made that mistake here, by stopping their 125 and 250 cr's and giving loyal customers no choice, they fully expected guys to just swap to their 4sts, that didn't happen and Honda suffered for sure, that along with all the problems they've been having, have IMO dropped the big red company well down the list
PREMIX IS THE FUTURE
