The new RS-12 system adds 5% max hp and 6.5% max torque to the new engine spec with its smaller throttle body and different ECU settings.

What does this translate to?

• Easier power delivery
• Smoother frontside torque
• Allows the rider to ride in an higher gear, thus freeing up suspension.
• Less rider fatigue
• Yoshimura’s RS-12 is proudly designed, developed and manufactured in Chino, California.
