01. Progressive performance
The FE 350w engine is designed to deliver maximum performance. Tilted two degrees backwards to further centralize mass, all major engine components and shaft arrangements are positioned to enhance overall handling and improve the anti-squat behavior from the chassis. Weighing just 62.1 lb (28.2) kilograms, the 350 cc 4-stroke engine is incredibly efficient.
The FE 350w features a DOHC cylinder head engineered to deliver performance and reliability. Internally, the layout features a new camshaft with low-friction DLC coated finger followers ensuring minimal friction. Together with the lightweight titanium valves - 36.3 mm intake and 29.1 mm exhaust - strong and controllable power is delivered throughout the rev-range.
Cylinder and piston
An 88 mm bore cylinder and forged bridged-box-type CP piston combine to create a compression ratio of 13.7:1. As a result, the low oscillating mass delivers strong and controllable power. High strength aluminium is used to manufacture both the cylinder and piston, with both components professionally engineered for outstanding performance and reliability.
The crankshaft is optimised for high performance and overall reliability with long service intervals of 135 hours. This has been made possible by using a plain big end bearing that features two force-fitted bearing shells.
The exhaust system is expertly designed to deliver class-leading performance at the lowest possible weight with the header pipe manufactured in two pieces. This design allows the header pipe to be removed without having to remove the rear shock. Further innovation allows for a short, compact silencer without increasing sound levels. The silencer is crafted from lightweight aluminum and stylishly finished with a black coating to highlights its premium quality and is an important component in making the new "w" model 50-state off-highway compliant, along with a USFS-approved spark arrestor.
