The biggest, baddest cruiser Honda has ever produced, the VTX is powered by
a 1795cc V-twin with 106 horsepower and 120 pounds-feet of torque. With an
exhaust valve bigger than a P-51's and an 18.8 kilogram crankshaft, the VTX
is the King Kong of performance cruisers. And because it's a Honda, the VTX
brings a new level of sophistication with a PGM-FI electronic fuel injection
system and a unique ChromaFlair pigment that alters the VTX's paint
(Illusion Red and Blue only) as lighting conditions change.
Unique VTX Features
· All-new V-twin engine is a 1795cc liquid-cooled 52° design that dwarfs
other production V-twin engines and hammers out immense power--106 hp at
5000 rpm and 120 lb.-ft. of torque at 3500 rpm.
· Advanced, high-pressure programmed fuel injection (PGM-FI) and electronic
digital ignition maximize power output and offer immediate throttle response
in any gear.
· High-performance suspension features a 45mm inverted front fork.
· Show-stopping street-rod styling with distinctive hooded headlight,
beautiful cast aluminum wheels and a dragster-style seat.
Engine/Drivetrain
· New V-twin 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 balance 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 engine hangers and
rubber engine mounts to eliminate unwanted vibration while preserving the
powerful character of the VTX engine's V-twin design.
· Three-valve cylinder head features two large, 36mm intake valves and a
huge, 45mm exhaust valve to produce optimum flow for the 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.
· Two 42mm-diameter throttle bodies deliver air to two specially designed
Denso 50-psi high-pressure fuel injectors. Fuel is delivered through 12
nozzle orifices in each injector, producing an atomized fuel mixture that is
highly combustible, for maximum efficiency and power.
· Electronic CPU provides individual, digital 3-D fuel injection and
ignition maps for each cylinder, creating ideal fuel mixture and spark
advance settings for superb rideability.
· CPU-controlled emission control system utilizes an air injection system
and three-way exhaust catalyzer to simultaneously reduce emissions of
hydrocarbons (HC), carbon monoxide (CO), and nitrous oxides (NOx).
· 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 camshaft-chain tensioners.
· Reliable electric-starter system.
· Handsome chromed two-into-one 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.
· New driven flange design at the final-drive gear eliminates final-drive
noise and wear and simplifies rear wheel installation.

SUSPENSION
· 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.
· Beautiful, satin-finish cast aluminum wheels.
· Wide, low, 130/70R-18 radial front tire enhances street-rod styling and
delivers superb handling.
· Aggressive 180/70R-16 radial rear tire puts the VTX engine's awesome power
to the ground and provides exceptional traction.
Additional Features
· Illusion Red and Illusion Blue paint with ChromaFlair brand light pigment
alters hue as lighting conditions change.
· Dragster-style seat boasts a low, 695mm (27.3 in.) seat height for
confidence during low-speed maneuvers.
· Chopped front and rear steel fenders complement the VTX's street rod
styling.
· Large, handsomely finished 17-litre gas tank with aviation-style fuel cap
offers extended cruising range.
· Tank-mounted chrome nacelle houses the fuel cap, tripmeter/odometer reset
and indicator/warning 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.
· Silver finish on crankcases and cylinders with milled fin edges complete
the custom street-rod look.
· 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.
· Semi-swept 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 20-amp-hour battery.
· Maintenance-free hydraulic clutch.
· Convenient push-to-cancel turn-signal switch.
· Transferable one-year, unlimited-mileage limited warranty.
