    This is the stage kit you want for your Honda. Go ahead and spend the money for the entire kit. This took my stock 2007 F12x to 66mph with awesome take off. I would spend the money again in a heartbeat. I now leave an R12x at take off and the R12x can not catch up. No, you will not outrun an 1800cc ski, but you are not going to use as much fuel either. You will be able to keep up with the newer 1800cc skis that are not modified. I have been very pleased, 3 years running the kit and no reliability issues.
