Both my buds have a drz 400e. I'm sick and tired hearing about this stupid button and how light they are. If they are so great, explain why i smoke both these guys when we hit anything that requires any kind of torque? They look like a bunch of two strokes trying to scream up these mountains. I putt right up almost anything in second gear at 5 mph. I was tempted to shift to first one time but i didnt want to destroy the trail for future riders. The DRZ 400e has no torque, which explains the need for the button. I guess i would want a button if i was stalled all day long on the sides of hills too....ha ha signed, BIG XR's p.s. if you have to add aftermarket engine items to a stock bike.....your buying the wrong bike to begin with.
