(Normal plugs cannot be used.)\n *Simultaneous installation of a reinforced crankcase, such as for the CD90, is recommended.\n *The cylinder and head of this product are larger than genuine parts, and depending on the combination with suspension parts, the tire may come into contact with the head.\n *Due to the bore \u0026 stroke up of this product, an increase in vibration may occur. Please be aware.\n *When installing this product, always install an oil cooler and oil temperature gauge and manage the oil temperature.\n *Continuous running at high temperatures (over 100 degrees Celsius) may damage the engine.\n *If used beyond the Daytona specified RPM range (MAX=13,000rpm), the engine may be damaged, so please be careful.\n *Takegawa reinforced crankcases cannot be installed because the cylinder skirt will interfere.\n *Images are for illustration purposes only, and the design and specifications of the products shown may change without notice.
