i think the main reason y two strokes blow up faster is cuz they have the mad acceleration, n for that people jump on the gas wit em n it makes em wear faster, four strokes dont really got the hard hittin accel so they r mostly used for trail quads cuz they dont really spin the tires or nothing, i would have to say 2 stroke, i love my shee for trails n drags, for wheelies i would rather have my blaster, the banshee is to long, i can still wheelie on it but i usually stand it up or the wheelies aint that long, the blaster i can pull wheelies for a while, n on a fourstroke its no comparison, they got more torque, i can pull wheelies on my neighbors 300 all the way down my street, i still say 2 stroke tho, l8r
