It makes a great desktop image.
The biggest, baddest cruiser Honda has ever produced, the VTX1800R is powered by a 1795cc V-twin with an exhaust valve bigger than a P-51's and a massive 18.8 kilogram crankshaft.
Full-flowing deeply valanced front and rear steel fenders, chrome-hooded headlight, broad fuel tank with tank-mounted instruments, pullback handlebar and floorboards with a heel-and-toe shifter combine to create classic styling that puts the VTX1800R in a class of its own.
Cast wheels similar to the VTX1800C's but with 'phat' 150/80-17 and 180/70R16 radial tires round off the VTX1800R's low-profile silhouette.
The VTX1800R. Outrageous horsepower in a mellow package.
Unique VTX1800R Features
· Beautiful retro styling with cast wheels.
· Full-flowing deeply valanced front and rear steel fenders, chrome-hooded headlight, broad fuel tank with tank-mounted instruments, pullback handlebar and floorboards with heel-and-toe shifter create a classic retro style that puts the VTX1800R in a class of its own.
· Classic taillight design.
· Staggered dual exhaust.
· 1795cc liquid-cooled 52-degree V-twin produces immense power--106 bhp at 5000 rpm and 120 lb./ft. of torque at 3500 rpm.
· Engine features 101mm cylinder bores and the largest connecting rods and cylinders Honda has ever made.
· Offset dual-pin crankshaft and two primary-shaft-mounted counterbalancer weights allow a high-performance engine design while eliminating harsh engine vibration. The result: muscular power across a broad rpm range for unequaled acceleration and roll-on performance.
· The 18.8 kilogram forged steel crankshaft uses bolted weights, reducing crankcase width nearly 50mm and reducing crankshaft weight 4 kilograms compared to a conventional one-piece design.
· The engine mounting system uses carefully matched hangers and rubber mounts to eliminate unwanted vibration, while preserving the powerful character of the VTX engine's V-twin design.
· Each three-valve cylinder head features two large, 36mm intake valves and a huge, 45mm exhaust valve to produce optimum flow for the incoming air/fuel charge.
· Two iridium-tip spark plugs per cylinder for efficient combustion at all engine speeds.
· Simple-to-service screw-and-locknut valve clearance adjusters.
· 4.5-litre airbox supplies a large volume of cool, clean air to the engine.
· Advanced, high-pressure programmed fuel injection (PGM-FI) features 42mm-diameter throttle bodies delivering air to two specially designed Denso 50-psi high-pressure fuel injectors. Fuel is delivered through 12 laser-drilled nozzle holes in each injector, producing an atomized fuel mixture that is highly combustible for maximum efficiency and power.
· Electronic control unit (ECU) provides individual digital 3-D fuel injection and ignition maps for each cylinder, creating ideal fuel mixture and spark advance settings for superb rideability.
· A unique dry-sump oil system utilizes a closed crankcase design and places the oil tank inside the gearbox case. The result is a freer-revving engine for improved power, and a lower engine height, allowing optimum rider ergonomics and a low, 695 mm (27.3 in.) seat height.
· Radiator with cooling fan maintains consistent engine temperature for optimum performance and long engine life.
· Maintenance-free automatic cam-chain tensioners.
· Reliable electric-starter system.
· Handsome chromed two-into-two exhaust system produces a deep, exhaust note.
· Primary drive gear uses a cam-type damper to minimize powertrain lash.
· Sturdy eight-plate clutch with clutch-center damper assures smooth gear shifting.
· Five-speed transmission with carefully selected gear ratios for relaxed cruising and exciting roll-on performance.
· Shaft final-drive system provides smooth, low-maintenance operation.
· Driven flange in the final-drive gear case eliminates final-drive noise and wear and simplifies rear wheel installation.
· Massive tubular steel frame contains the engine's power and gives the VTX a long, low, muscular stance.
· Large, 45mm inverted front fork provides 130mm of plush yet responsive wheel travel.
· Dual chromed rear shocks have 100mm of wheel travel and feature an advanced internal valve system for a comfortable ride.
· The VTX's braking system features two three-piston front calipers and a single two-piston rear caliper. Application of the front brake lever activates the two outer pistons of the front calipers. Application of the rear brake pedal activates the two pistons of the rear caliper and the center pistons of the front calipers only. When only the rear brake pedal is used, an inline pressure valve delivers proportioned application of the front caliper center pistons.
· Cast aluminum wheels with radial offer a classic look.
· Fat, 150/80 radial front tire on a 17-inch wheel gives the VTX1800R a commanding profile.
· Fuel tank capacity of 20 litres for extended touring range.
· Relaxed handlebar position and large levers contribute to the classic design.
· Classic taillight design.
· Seat boasts a low, 695 mm (27.3 in.) height for confidence during low-speed maneuvers.
· Retro-styled front and rear fenders complement the VTX's classic cruiser styling.
· 20-litre fuel tank for extended cruising and touring range.
· Tank-mounted chrome housing features a speedometer, odometer/tripmeter, aviation-style fuel cap, and indicator lights for the turn signals, high beam, neutral indicator, low fuel level, oil pressure, coolant temperature and fuel injection.
· Extensive chrome finishing of engine parts includes cylinder head covers, valve inspection covers, spark plug covers, airbox cover, left crankcase cover, clutch cover and left-rear engine cover.
· Distinctive chrome-hooded headlight housing features a powerful, 55W/60W halogen bulb with a computer-designed multi-reflector for superb lighting in all conditions.
· Large speedometer with easy-to-read numerals.
· New laid-back handlebar design provides a comfortable upright riding position.
· Comfortably padded large-diameter handgrips with polished aluminum handlebar switch housings and triple-clamp assembly.
· Reliable 300-watt alternator.
· Durable, maintenance-free 18AH battery.
· Convenient push-to-cancel turn-signal switch.
