Yamaha VMAX

Yamaha VMAX









  • The ultimate power cruiser delivers unmatched performance from its 65-degree, four-valves-percylinder, 1679cc V4—plenty of eye-opening, controllable acceleration from a compact engine that looks as powerful as it is.
  • Downdraft four-bore fuel injection with YCC-I intake technology and YCC-T fly-by-wire throttle provide awesome acceleration throughout the broad powerband.
  • Lightweight aluminum chassis puts the engine low and forward for mass centralization, resulting in a machine designed to handle curves as well as straightaways.
  • Borrowing liberally from advanced sportbike technology, VMAX features a slipper clutch, wave-style brake discs, master cylinders, ABS, and complete suspension adjustability front and rear.
  • Functionality and forward-thinking style uniquely combine with features like oxidized-titanium coated 52mm front fork tubes, magnesium engine side covers, fluorinated polyethylene fuel tank and the organic electroluminescence multifunction display.

Engine:

  • * The thunderous 1679cc, 65-degree, liquid-cooled, fuel-injected four-valves-per-cylinder, DOHC engine pumps out astonishing power to reinvent the VMAX legend.
  • The sportbike-proven Yamaha Chip Controlled Intake (YCC-I) switches nearly instantaneously between 150mm and 54mm intake funnels as needed for a broad powerband that delivers optimum performance at any rpm.
  • Yamaha Chip Controlled Throttle (YCC-T), the fly-by-wire system, delivers optimum acceleration under all conditions.
  • Engine combines four-valve technology with a high 11.3:1 compression ratio, forged aluminum pistons and NGK® Iridium spark plugs with R1-type direct ignition coils to extract maximum horsepower from the fuel charge.
  • Cams are driven by a combined chain and gear system to precisely control valves while keeping cylinder heads remarkably compact for such a large displacement engine.
  • Hydraulically activated clutch includes racetrack-proven ramp-type slipper clutch system that makes braking from speed while downshifting smoother.
  • Five-speed transmission has superbly spaced gear ratios to take full advantage of the engine’s awesome power in straight-line acceleration or through the canyons.
  • Four-into-one-into-two-into-four exhaust system with EXUP® delivers a broad, seamless powerband with the right VMAX look.
  • Delivering this power cruiser’s muscle to the street means a beefy shaft drive just like its predecessor. Special shaft design includes two cross joints to accommodate the fat 200/50 R18 rear tire.
  • The high-performance engine is cooled by two radiators for efficiency and clean looks. Lubrication is via a simple, reliable wet sump system.
  • The iconic VMAX aluminum intake covers are hand buffed by craftsmen for superb quality and individuality.

Chassis/Suspension:

  • The chassis is light and compact, with a cast aluminum main frame, CF die-cast and extruded aluminum rear frame and cast aluminum swingarm. The result is superb rigidity balance for both hard acceleration off the line and corner carving.
  • Cartridge-damper-type front forks have substantial 52mm inner tubes with oxidized titanium coating. Forks have both compression and rebound damping adjustability plus spring preload.
  • Link-type Monocross® rear suspension has a piggyback reservoir and features compression and rebound clickers, plus remote preload adjustment.
  • VMAX uses Brembo®-designed master cylinders, the front with radial pump and reserve tank. Large 320mm wave-style dual front discs are matched to radial-mounted mono block 6-piston calipers. On the rear wheel, there’s a 298mm disc, also wave design, and single-piston caliper. These high-tech brakes also incorporate three-position ABS.
  • Tapered handlebar provides a muscular 1-1/8” diameter look at the triple clamp while using conventionally sized controls.
  • 18-inch radial tires, 120/70 R18 front and 200/50 R18 rear, are mounted on cast aluminum five-spoke wheels.
  • For mass centralization that contributes to the bike’s lean looks, the 4 gallon (15-liter) fuel tank is mounted under the seat, with the filler under the rider’s backrest. Tank is constructed of fluorinated polyethylene with superb permeability resistance.

Additional Features:

  • The Electronic Control Unit (ECU) uses three microprocessors to control fuel injection, ignition, YCC-T, YCC-I, meters and other electrical components.
  • The instrument panel includes an analog, step-motor driven tachometer and digital speedometer with LED indicator lights. Prominent LED shift timing indicator adds to the performance character of the new VMAX.
  • Organic electroluminescence multi-function display provides a more precise display vs. LCD and includes clock, fuel meter, trip meter with fuel reserve trip meter, transmission gear position, coolant temperature, stopwatch and more.
  • Distinctive key design reinforces the unique character of this new VMAX.
  • H4 60/55W headlight provides excellent visibility and distinctive style, while the trick-looking LED taillight is light, bright and highly efficient.
  • Rare earth magnet AC magneto puts out a robust 420W at 5000 rpm.
