Ultra-lightweight 998cc, DOHC, 20-valve, liquid-cooled, 40 degree inclined, in-line four-cylinder engine produces 150 hp at 10,000rpm. The engine has been tuned to provide outstanding performance and incredible passing performance.
The crankcases, pistons, cylinder and cylinder head are based on the 3rd generation R1 powerplant ('04 to '06).
Combustion chamber design and squish area has been optimized for maximum sports performance. The compression ratio for the FZ1 is 11.5:1. Redline is set at 12,000 rpm and features a "soft" rev limiter to protect the engine.
Special lightweight, high lift, high performance intake and exhaust cams help to provide incredible horsepower and fast engine response. Cam profiles and the cam timing are designed to provide for more low to midrange power (VsR1) .
Automatic cam chain tensioner reduces both maintenance and engine mechanical noise.
Lightweight, 3rd generation R1 based crankshaft provides quick engine response. The inertia moment or mass of the crank has been increased by aprox. 40% (Vs 2006 - R1) for improved low to mid range engine performance.
