First sled with all Air Suspensions, EPS Preformance and Preformance-Enhancing EXUP Technologies!
•Top Performance 4-cylinder Genesis 4-Stroke engine
The physical casting of the engine remains the same, but the valve timing, intake and exhaust tracts, airbox and exhaust pipes are all recalibrated for optimum midrange torque output as well as an overall top end gain.

•Airbox/intake
The Intake tracts on the new Apex SE have been lengthened by 11mm, as compared to the previous model. The engine utilizes the pressure waves in the longer intake tubes and in the airbox to boost airflow and maximize high RPM performance.
•Injector
The distance between the throttle valve and intake valve has been redesigned for optimum fuel delivery. In addition, the 4-hole injector on the throttle body creates a spray of finely atomized fuel, with droplets of just tenths of a micron in size. The spray is aimed directly at the intake valve skirt for maximum efficiency and performance. The result? Simply unmatched throttle response.
•EXUP and new exhaust pipe
Yamaha-exclusive EXUP valve technology controls the exhaust pressure waves for optimum intake and exhaust efficiency, delivering unmatched overall performance with more midrange torque. Additionally, the exhaust pipes have been enlarged to 38mm from 35mm for added exhaust pressure wave efficiency.
•15 x 128 x 1.25” Ripsaw track
The new 128-inch track length is longer to harness the new Apex’s huge midrange torque for great acceleration. The track has an open design to accept extrovert drivers.
•Engine Braking Reduction System
The new Top Performance Genesis 4-Stroke engine features the unique Engine Braking Reduction System. The system allows a small amount of air to pass through the fuel injection system when the throttle is released, giving riders more of a “coast” feeling.
