High-performance, 1854cc (113 cubic inch) air-cooled, long-stroke, OHV, 4 valves per cylinder, 48°, V-twin powerplant produces massive torque and class leading acceleration from very low rpms.

Maximum torque occurs at 2,500 rpm while maximum power occurs at 4,500 rpm, providing exciting acceleration with great pulse / torque feel.

Traditional pushrod valve actuation keeps engine height down for a lower centre of gravity and ensures more uniform heat dissipation due to absence of a cam chain case. A lower centre of gravity helps to insure light, easy handling.

Four-valve cylinder heads provide optimal breathing efficiency for great power delivery at all rpms. The two spark plugs per cylinder means faster, more complete combustion for maximum power output.

Cylinder head design utilizes a pent roof combustion chamber design and features an oil passage near the exhaust valve seat to improve cooling and durability. The heads also feature engine mounting points on each side of the head for increased chassis rigidity for exceptional handling.

Large size valves increase engine horsepower and torque. The intake valves are 36mm in diameter while the exhaust valves are 31mm.

Specially designed valve train includes short design intake and exhaust rocker arms that reduce inertia during high-rpm use.

High performance spec twin, crankcase-mounted, high-lift cams ensure strong torque and class leading acceleration.

Mechanical centrifugal decompression mechanism located in each of the exhaust camshafts, insures fast, easy starts. This new system is contained inside the camshafts and reduces weight since no solenoid etc. is required and complexity.

Hydraulic valve lifters driven by the twin camshafts deliver exceptional performance and significantly reduce maintenance and tune-up requirements.

The crank shaft is a single pin design, providing that special V-twin sound and pulse feel. Optimized flywheel mass and "damper-less" crankshaft allows the rider to feel the directness of the engine's power.

For each rotation of the rear wheel, in 5th gear, the crank spins 3.14 times providing an outstanding rear wheel driving force feeling to the rider.

Compact design dual balancers reduce vibration for exceptional rider and passenger comfort. The balancers are positioned on either end of the crankshaft to reduce vibration and to minimize the size of the engine cases. The balancer is designed to reduce vibration while still allowing that classic V-twin pulse feel.

3-axis crankcase layout means the crankshaft, main axle and drive shaft are specially arranged to minimize the size of the engine cases and centralize mass.

The dry sump oil lubrication system has been optimized to ensure maximum lubrication and cooling. Special oil nozzles direct oil at the bottom of the pistons to cool and lubricate them. Dry sump system means a more compact engine design since the oil tank is not part of the engine, which lowers the centre of gravity for great handling and a light feel.

Special "dual chamber" crankcase design. The front section is for the crank assembly while the rear is for the transmission. Two, 3-rotor high capacity oil pumps optimizes oil flow in each of the two main sections of the engine.

Huge 100mm bore ceramic composite-plated cylinders provide uniform heat dissipation, reduce weight, reduce friction and increase cylinder service life.

Large-diameter pistons are both durable and lightweight. Yamaha's exclusive "controlled forged construction" keeps the pistons light for faster response and to accommodate higher-rpm performance with reduced vibration and less reciprocating mass. The pistons feature an Alumite coating to reduce friction.

Cooling fin thickness and depth is optimized for maximum heat dissipation, thereby eliminating the need for liquid cooling, while maintaining that traditional, stylish air-cooled engine appearance. Each cooling fin is specially polished to create shining highlights that change with the angle of the light.

43mm, twin-bore, downdraft throttle body fuel injection (FI) with throttle position sensor (TPS) ensures great throttle response and maximum power throughout the rev range. This system is a "closed loop" system, since it utilizes an oxygen sensor in the exhaust to monitor the concentration of oxygen and adjust the FI system if necessary. The benefits of fuel injection include chokeless operation, increased fuel economy, instant throttle response and reduced emissions.

The 12-hole, 2-directional Mikuni fuel injectors produce a wide spray pattern for complete cylinder filling. This special spray pattern combined with the dual spark plug head ensures complete combustion for maximum power. An Idle Speed Control (ISC) has been adopted to ensure stable idling performance.

High capacity electronic fuel pump is located in the sub tank under the seat.

State-of-the-art Electronic Control Unit (ECU) ensures precisely metered fuel delivery and optimal ignition spark control using 3D transistorized coil ignition mapping for each cylinder.

3.5 litre dual inlet air filter box features one inlet at the front and one at the rear of the airbox for maximum breathing efficiency. This new design not only maximizes air flow but also reduces weight and allows for a more open appearance at the steering head area. A viscous paper type air filter is used.

Air Induction System (AIS) injects fresh oxygen at the exhaust port to insure complete combustion thereby reducing harmful exhaust emissions (HC & CO) while a special air cut valve reduces backfiring when decelerating or coasting off throttle.

High-performance, 2-into-1-into-2 exhaust system features large size header pipes for maximum flow. Dual 3-way honeycomb matrix catalyizers reduce harmful exhaust emissions. The stylish dual muffler helps to boost torque and horsepower while producing a throaty, V-twin growl. Heat shields protect the rider and passenger from hot components.

The exhaust system also features a lightweight titanium EXUP exhaust power valve most commonly found on high performance sport bikes. The EXUP system not only provides crisp throttle response and eliminates 'flat spots" but also improves acceleration, reduces fuel consumption and harmful emissions too.

Smooth-shifting, 5-speed transmission features optimized gear ratios for both strong low rpm acceleration and relaxed highway cruising. 5th gear is an overdrive gear for reduced engine rpms at highway speeds for maximum riding comfort.

Heavy duty 10 plate clutch is designed compliment engine power characteristics. This new clutch is operated by an all new hydraulic master cylinder instead of a cable. The hydraulic clutch design is low maintenance, self adjusting and very stylish.

Low-maintenance belt drive system not only significantly reduce maintenance but is also clean and quiet. A belt drive system uses less power than a shaft drive and reduces unsprung weight for great rear suspension performance.

Easy access, spin-on type oil filter means fast, easy oil changes.

High tech, cast aluminium double-cradle frame reduces weight, while balancing strength and rigidity. The engine is rigidly mounted in the frame for added rigidity. The critical head pipe area features box type construction for additional strength. The frame not provides excellent handling characteristics but also compliments the beautiful flowing lines of the entire machine. The open area behind and below the steering head helps to enhance that "chopper inspired" styling image. The main front wire harness is hidden in the head pipe for a clean appearance.

Important Note: Raked out front fork with lots of trail generally provides good straight line stability but often provide heavy steering. The engineers at Yamaha will not sacrifice handling for styling, so they have developed a 6 degree yoke angle combined with a 34degree steering head for a total fork angle of 40 degrees. The XV1900 provides light "athletic handling and easy steering" not commonly found on a custom styled bike. This bike was designed to be ridden !! Key numbers: 6 degree yoke angle; 34 degree caster angle; 152mm of trail.

Lightweight C.F. die cast aluminium swingarm offers superb rigidity and ensures excellent stability and handling. The C.F. die casting process allows for beautiful shapes that are both strong and light. This swingarm is a fashion statement in aluminium and compliments the rest of the XV1900 eye catching styling.

Rigid 46mm Kayaba front fork offers 130mm (5.1") of wheel travel for exceptionally stable handling and great ride comfort. The inner fork tubes are protected by stylish chrome chip guards.

Beefy, cast aluminium, top triple clamp and computer designed lower triple clamp with a 6 degree yoke angle provides excellent handling qualities while maintaining that custom chopper inspired styling.

Link rear suspension features a spring preload adjustable single rear shock delivering outstanding ride comfort and precise handling. The Kayaba shock is horizontally positioned under the engine for a lower center of gravity and is hidden to provide that classic "hardtail" look. Rear wheel travel is 90mm (3.5").

Powerful dual 298mm floating front discs are squeezed by ultra rigid, 4-piston, monoblock calipers to provide sport-bike spec stopping power. Providing exceptional stopping power, these brakes also provide great lever feel and feedback.

Beautiful custom looking 5-spoke cast aluminium 21" front wheel provides a special styling highlight. The width is 3.50 inches wide and is fitted with a 120/70 profile tire. The rear wheel is also a custom inspired 5-spoke 18 inch cast aluminium mag design that is 7.5 inches wide. This rear wheel carries the widest rear tire ever installed on a Yamaha motorcycle … it is a 210 / 40 tire. Both wheels are fitted with tubeless tires.

Large 310mm rear disc is squeezed by a single piston caliper mounted below the swingarm for a lower center of gravity and that customized "hidden look".

Low maintenance, clean, quiet belt drive eliminates messy chain splatter while maximizing power output. History has proven that belt drive systems are ultra reliable and rarely need alignment or tensioning. The belt is embedded with carbon fiber for incredible strength.

Two-piece seat design features a deep notch in the rider seat to give that chopper inspired riding position … more sitting in than sitting on. The rear portion of the rider's seat also doubles as a backrest / back support for the rider.
