900ACE
Unleashing the Power of the Rotax 900ACE
The Rotax 900ACE is a versatile triple-cylinder engine found in everything from the Can-Am Maverick Trail and Ryker to Sea-Doo watercraft. While it is known for its reliability and efficiency, there is a wealth of untapped performance hidden within its valvetrain. Kelford Cams has developed specialised camshafts for the 900ACE to help enthusiasts unlock the true potential of this compact powerhouse.
Optimising the Triple-Cylinder Power Band
Our Kelford technicians have spent time analyzing the airflow characteristics of the 900ACE cylinder head. By increasing the valve lift and duration, we allow the engine to breathe more effectively, which is particularly beneficial for those looking to improve throttle response and top-end speed. Whether your 900ACE is naturally aspirated or turbocharged, our camshafts provide a more aggressive power curve that makes your vehicle feel lighter and more responsive.
