F25
A compact motor - but with serious power and style
Open up the throttle on the F25 and you'll understand why it's in a class of its own: a versatile, twin-cylinder 4-stroke, it offers big performance allied to a smooth ride. And while brilliant fuel economy and easy handling come as standard, the engine is also kinder to the environment, with reduced exhaust emissions.
Extra benefits, normally only found on larger engines, include computer-controlled ignition, a special light-load starting system, and a large-volume silencer.
With single-lever steering friction adjustment, a high-output alternator and the Wide Range Power Trim & Tilt system option, the F25 makes a great choice for commercial, professional or leisure use.
