Had an 06 rmz 450 did the Athena big bore Dr. D exhaust, twin air power flow, shock therapy suspension. The big bore gave it more grunt but sacrificed some revs.

I did one on my DRZ400. Deff more grunt.

My RMZ450 has tons of power stock. But I'm no pro.

I did cams, BB, full exhaust and better carb on my DRZ. Deff not the same bike I took off the show room floor so I imagine those mods on an RMZ would be BIG!!!

Let us know what you do and the outcome.
