Other high - tech features include variable camshaft adjustment, four - valve technology with bucket - type
tappets, a particularly rigid aluminum crankcase
of closed - deck design and the low - friction TWAS coating on the cylinder contact surfaces.
Credit for this longevity goes to long - wearing platinum - tipped spark plugs, a long - life timing chain, and careful engineering
of the precisely manufactured DOHC valvetrain - which reliably maintains proper valve
tappet clearances until the first tune - up.
