"When it's time to service the 450 cc YFZs, choosing the right cylinder kit makes all the difference and Big Bore cylinders are not the only way to upgrade performance and durability. Whether the aim is to restore original reliability or achieve a tangible performance upgrade, Athena offers two complete, proven solutions: the 95 mm Standard Bore 450 cc replacement, as well as the 98mm Big Bore 478 cc kit that is designed for riders seeking increased torque and stronger acceleration."
All Athena cylinder kits owe their reliability and performance to the racetrack, and the Big Bore kit was raced by Simone Mastronardi at the 72 Heures de Pont-de-Vaux – the iconic international endurance race where engines are subjected to 72 hours of continuous stress with no margin for error.
The ideal choice for restoring the original configuration, the Athena standard bore kit is a complete, ready-to-install kit engineered to ensure durability, smooth operation and maximum reliability.
The kits include an aluminum cylinder with nickel-silicon carbide plating, a piston that has been designed to further reduce friction and gaskets developed to ensure optimal sealing.
The 98 mm/478 cc Big Bore big brother kit is for those looking for a real performance upgrade. Engineered to deliver increased displacement and stronger power output while, maintaining the necessary durability, the precision matched components withstand high temperatures and pressures.
