YFZ350 Banshee

The Last of the Interceptors
You know that feeling you get when you hear a special engine? The noise hits you like a clip under the ear and your cerebrum scrambles to digest and dissect it as a concert of cylinders in harmony, induction whir, combustion and exhaust note. The bristles stand up atop your spine and your emotions lift with excitement and optimism - and suddenly new things are possible. Tell you one thing, Banshee’s 347cc, liquid-cooled, two-stroke twin will get your adrenaline pumping, well before you let out the clutch lever. No machine has ever matched Banshee’s list of dirt-track, desert race and other titles, or for that matter, its sheer uniqueness. It’s a legend. Get ‘em while they last.
It starts with a burbling rumble that, with the flick of a digit grows to a fearsome shriek, breathing through twin exhausts. Nothing epitomises the almost organic life force of the internal combustion engine in the same way as the two-stroke Yamaha Banshee.
And nothing gets your own life force standing to attention like 347cc of twin-cylinder, liquid-cooled Grand Prix-derived racing two-stroke surging hard through the gears.
Over a long and distinguished career worldwide, Banshee has won more races than you’ve had hot breakfasts, and it still continues to attract its own legion of loyal, hard-core fans for simple uniqueness and seat of the pants excitement. There’s nothing that looks like it, or thrills like it.
FEATURES
♦ The most distinctive engine in the sport, Banshee’s powerplant is a liquid-cooled, 350cc, 2-stroke with twin YPVS-equipped cylinders, twin carbs and dual exhaust.
♦ Banshee turns like it revs - lightning quick, thanks to its low seat height, rigid, lightweight frame design and nimble geometry. Lightweight alloy wheels are shod with low-profile tyres and slowed by triple disc brakes.
♦ Twin 26mm Mikuni carburettors ensure potent, seamless acceleration and top-end power, while the unique twin expansion chamber system emits a dramatic and unmistakeable note.
♦ Large-diameter ventilated hydraulic front and rear disc brakes help reel in all that incredible Banshee speed with tremendous stopping power even in wet conditions.
♦ Rigid, lightweight swingarm with a rising-rate, link-type piggyback-reservoir single rear shock is adjustable for preload, compression and rebound damping and 221mm of travel permits a huge range of fine-tuning to rider style and terrain conditions.
♦ Heavy-duty front grab bar protects suspension and Banshee’s awesome 347cc two-stroke twin- YPVS-equipped cylinder power plant. Twin spotlights add an appropriately distinctive touch.
