I wonder why they keep the twostrokes at all? Is it so the factories can continue to develop their weedeater motors? :-P

I think state side only the Aprillia is available (RS250). Other than that it is all imported Euro versions, but all the Jap companys make 2 strokes. They just sell them in Europe or Asian markets only:( I think a modified 2 stroker would be a hoot :twisted: , but the extra $ for a specilized toy as that is not in my near future :roll:

in praise of two strokes. . .

I started out riding two strokes-a '72 Suzuki 250 enduro, then a 1975 550 cc three cylinder GT 550. Too bad they can't meet Federal air quality standards so they can sell them here. That 550 was REAL fast even if it did sound like a swarm of bees!
