Featuring the latest technology, the FE 501 engine is fully redesigned for MY17. With increased performance, smaller dimensions and a weight saving of 1.7kg as well as a revised cylinder head and class-leading electronics, the 510.4cc power plant is more advanced while weighing only 30.1kg
The new crankshaft offers 5% added inertia without increasing weight. Additionally, a shorter connecting rod and new crankshaft position improve mass centralisation and contribute to the compact design. A plain big end bearing comprising of two force-fitted bearing shells ensure maximum reliability and durability, guaranteeing long service intervals of 135 hours.
The compact SOHC cylinder head is designed to offer the maximum performance at the minimum possible weight. The new camshaft actuates four lightweight valves (titanium intake Ă˜=40mm 32,6g, steel exhaust Ă˜=33mm 42,6g) through a very robust rocker arm system. Additionally, the timing drive is revised with a new, shorter timing chain and friction optimised chain guides which reduce drag and increase efficiency and performance. Overall the more compact design is now 350g lighter.
Chromoly steel frame
While keeping the same successful geometry from MY 16, the hydro-formed, laser-cut and robot-welded frame is expertly crafted by WP Performance Systems. The 6mm wider and 2 mm lower steel tubes offer 20% higher torsional rigidity while longitudinal stiffness is reduced by 30%. The increased torsional rigidity improves stability and agility while reducing the longitudinal stiffness creates increased flexibility for better bump absorption and suspension functionality. The new frame weighs only 8.8 kg making it 0.6 kg lighter than its predecessor.
