I am glad that the 2-Stroke is still alive. I hope that with some modern technology like the fuel injection that they make a come back.
that would be sweet! fuel and oil injected 2 stoke
I noticed on your solo mission you were on a 4 stroke….. what happened to the YZ 2 stroke you have been rockin?
I rode that 450 last year, this year I have the YZ 250, I wish I had one of each. 450 for tracks and dunes and 250 2 stroke for everything else.
I dont know man…. I rode a cr 450 at the dunes and HATED it! Would rather have my yz 250, but thats just me. Maybe the KTM or other 450s would better suit my style at the dunes than the Honda did?
The 4 strokes are very front end heavy in the dunes, but have so much torque that they go any where without having to rev them to the moon.
i think for the average guy who rides a lot a two stroke is the only way to go, not always the case if you race. unless it’s joe somebody who has a bike but only rides two, three times a year. He needs a cheater bike to tractor around with. but the two stroke is a free-riders weapon of choice i feel. the two stroke can be ridin put in the garage all winter and will fire up first time, cost of riding is way lower, if you truly love to free-ride the weight of the two stroke is something four strokes cant give you, ex. 2010 yz450f. I use to take my four strokes to Saint A and other dunes and that thing hated life there. (unless i was using a knobby which at Antons you can get away with, but two strokes and paddels! match made in heaven.) My two stroke has no trouble and seems to do a lot better on sprockets, chains, and gas i use to have to pack gas to get to devils dune and back with my old four strokes. Then I come home and get to do a piston. The two stroke i get home slap the knobby on and go shred some good ole colorado free-ride areas. plus if you come from a free-ride mtn bike background my 09 yz 250 feels like a heavy dh with a motor (its a tough feeling not to love)!!
