They keep your body position more centered over the bike. With the DJ bike, if your bars are too low your body weight will be too far forward making the nose of the bike dive when you're in the air. However, there is a thing as too tall of a bar where it instantly feels like it's up in your chest upon take off. Sometimes it takes a couple tries before you get the bar height that feels right for a particular bike. But also yes, on take offs if the bar is too low it will feel like you are really fighting to pull up on the bike.

 Dude, it was kinda crazy how I got it.....found it brand new on eBay and the guy had it listed for $350 'Buy It Now' or 'Make An Offer'. Just for shits and giggles I threw out an offer of $200 and got automatically denied, threw out another offer of $250 got it automatically denied, so I was done with it because I didn't want to bid anymore than that with the $50 shipping. Forgot about it til 2 days later when the seller messaged me saying he lowered the bid denial so if I bid $251 it was mine.....I couldn't click quick enough. So for $301 shipped I got a brand new acid Majesty dirt, the frame/color I've lusted over.

 @Draggon: That's a score! I had a similar thing happen with the Majesty (dirt) frame I got a while back. I just keep selling them, and the regretting it down the road. I have that NS steel 27.5 hardtail I ride now, and it basically has the dj geo... but I miss the shorter wheelbase for messing around out in the street. As per usual, you got a fantastic setup there.

 Shit, best thing in a shop. I can set frames/parts down without worry, work on them on it as well......plus I am a god damn surgeon, 4 years so far and not one stain.

 Thanks Niko!! It's my home away from home at my home

 I know that feeling, I woke up this morning and spent an hour in my shop just fiddling around!
Its great to have a home away from home!

 @nikoniko: It really is, I visit at least once a day even if I don't have anything to do in there.......who am I kidding, we always have something to do in there, am I right or am I right!!?!?!?

 Thanks man, I am a lucky man!!
