Anybody have 900 headers?

Considering the low mount option if I can find headers at a decent price. Also, can someone tell me the diameter of what the headers pipe should be right before the down pipe? Thanks

Any of the 1992-1998 (Don't hold me to that) CBR900RR headers, stock or aftermarket, can be made to work pretty easily.

The pipe flange diameter (where it fits into the head) is 41.25mm I believe - You would also need to take into consideration the flange bolt and tube spacing.

The actual header pipe is only around 35mm - probably contributes to the torque of 919.....


Hope this helps

Anytime, my pleasure!

I was in Houston this week - left before the storms rolled in. Almost made the trip to Austin - very nice place to be.

Good luck and any questions, someone here should be able to help.

I could be mistaken but I believe there were 2 versions of the oem 900rr headers. I think the later ones fit the 919 and the early ones don't due to interference with something. I'm not sure what year they switched.

I had to cut a small frame bracket off to get the early header to fit.

It might of been for the center stand, with wheel stands, I did not care.

Good point, thanks for mentioning it.
