• The valve spring retainers are lightweight aluminum instead of steel, and valve spring pressure is lighter for reduced valve-opening force. This contributes to superior low-to-midrange torque characteristics due to less power-robbing friction. There’s also a higher lift cam profile, while valve stem ends are chromium-nitride coated for exceptional reliability and reduced maintenance.
• The Bilateral Beam frame is crafted from a carefully chosen combination of forged and extruded aluminum pieces – 20 in all – all welded together to provide unmatched rigidity balance.
• Riders have a choice of two color options: Team Yamaha Blue and White or White and Red.
