ok rather than going out behind the house to measure this, how high of a riser can i put on my bars using the original brake, and throtle cables and stuff, i would like to go with a 3 or 4 inch higher setup, and for those who dont remember me i ride a 01 ZX. :D

Panteraone has a 3in or 3.5 in on his (isovibe) and I am pretty sure he said that was the limit. If Im wrong he will correct me later.

I would say that 2" is the safe limit, but I know some guys have gone 3".

ok ill try to explain this.i went up 3.25-3.5 inch and also moved the bars forward 1/2 to 3/4 inch(the isovibe allows this)and im at the limit,now if you just rise without moving forward 2 inch-2.5 is prob the limit with all the cables staying stock

I put on a 2 inch riser and had no problems. I used Powermadd. By the way, I am very happy that I added the riser. Much more comfortable for me.

Can a riser be added to a REV X?

I just put the isovibe on my 2001 zx 600 and it brought the bars up 2.5 almost and cut one wire tie and cable still has slack in it.

mxzx600,i used one piece of the stock doo bar clamps under the isovibe to give me some more height,brought me up a little more than 3.25 :p
