Last year the Racer X test crew put together a big-bore shootout that pitted each of the brands against one another with 270 kits installed. Each engine responded differently to the drop-in kits, and our creative director, Langers, really liked what it did to the Suzuki. When he asked if he could spearhead a project with the RM-Z we let him have at it.
