The 350 cc DOHC engine weighs in at only 60 pounds with a maximum power output that rivals 450 cc machines. The engine is specifically designed with performance, weight and mass centralisation as key areas. As a result, all shaft arrangements have been positioned to allow oscillating masses to occupy the ideal center of gravity while all parts are engineered to offer the best performance while adding the least possible weight.

The FC 350 features an advanced DOHC cylinder head layout meticulously engineered to deliver every fraction of performance. The internals feature polished camshafts and DLC coated finger followers, resulting in minimal friction and unsurpassed overall performance, allowing the engine to rev freely to 13,400 rpm.

An 88 mm bore and 57.5 mm stroke cylinder features a compression ratio of 14:1 and a large diameter yet lightweight forged bridged-box-type piston. As a result, the low oscillating mass delivers exceptional power, high revs and a very wide power band.

Designed with precisely positioned inlet ducts aimed at reducing drag and air flow deformation, the airbox ensures unrestricted airflow with maximum filter protection. The TWIN AIR filter is easily accessed without tools, by simply removing the left side panel for easy maintenance. Offering further performance customisation, the MY20 FC 450 is delivered with an additional airbox cover that can be changed without the use of any tools for a sharper throttle response according to rider preference or track conditions.
