I recently installed the same setup on my DS. Like it a lot. I paid about $120 for bars and clamp from RMATV

 

i highly recommend renthals for its strength since i flipped my bike end over end (not cartwheel) last summer bending my stock steering stem and busting both levers among other things all the while leaving the handlebars intact .

 

i swear by renthals and will never settle for another brand. the 300ex was flipped 6 times in the last 2 weeks, every single time it was end over end, either forwards or backwards, causing the handlebars to be the first thing to hit the ground and no damage has been done to them. i have also had a set on the blaster for over a year and they also have seen a considerable amount of abuse with no complaints. they feel great and hold up like no other.
