"Neo Streamline" styling
Features and Benefits (Canada)
" 1854cc high-performance, air-cooled, long-stroke, OHV, 4 valves per cylinder,
48°, V-twin powerplant produces massive torque and class leading acceleration.
" 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 a 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 new 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 system is contained inside the
camshafts and reduces weight and complexity since no solenoid etc. is required.
" Hydraulic valve lifters driven by the twin camshafts deliver exceptional
performance and significantly reduce maintenance and tune-up requirements.
" 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.
" 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.
" 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.
" Ceramic composite-plated cylinders provide uniform heat dissipation, reduce
weight, reduce friction and increase cylinder service life.
" 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.
" Optimized "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
" 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.
" "Tri-axis" crankcase layout means the crankshaft, main axle and drive shaft
are specially arranged to minimize the size of the engine cases and centralize
" 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
" 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. A 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 is located under the tank. There are
intake ducts at the front and rear of the air box for maximum breathing
efficiency. This design not only maximizes air flow but also reduces weight. 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
" High-performance, 2-into-1-exhaust system features large size header pipes for
maximum flow. The single muffler contains a 3-way honey comb matrix catalyizer
to reduce harmful exhaust emissions. The stylish muffler helps to boost torque
and horsepower while producing a throaty, V-twin growl.
" 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 and reduces fuel consumption and harmful emissions.
" Dry sump lubrication 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. A handy, spin-on oil filter means fast, easy oil
" Frame mounted oil cooler is a first on a Yamaha cruiser. The cooler maintains
consistent oil temperatures for optimum cooling and lubrication of this massive
" Smooth-shifting, 5-speed transmission features optimized gear ratios for both
strong acceleration and relaxed highway cruising.
" 2-piece heel-and-toe shifter adds versatility and enhances the overall
cruising experience. The 2-piece design allows the rider to individually adjust
front and rear portions to suit foot size or remove the rear section if not
" Heavy duty 10 plate clutch is designed compliment engine power
characteristics. This clutch is operated by a hydraulic master cylinder instead
of a cable. The hydraulic clutch design is low maintenance, self adjusting and
" 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.
" High tech aluminum, die cast, double-cradle frame reduces weight, while
balancing strength and 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 rest of
the chassis and bodywork. The engine is rigidly mounted in the frame.
" Lightweight C.F. die cast aluminum 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 aluminum and compliments the rest of the Roadliner's eye catching
" Rigid 46mm front fork offers 130mm (5.1") of wheel travel for exceptionally
stable handling and great ride comfort. The fork features "slash cut" large
diameter fork shrouds to enhance the "neo- streamliner" styling.
" Beefy, cast aluminum, top and bottom triple clamps help increase fork rigidity
and reduce weight.
" Link rear suspension features a spring preload adjustable single rear shock
delivering outstanding ride comfort and precise handling. The 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 110mm
" Powerful dual 298mm floating front discs are squeezed by ultra rigid,
4-piston, monoblock calipers provide sport-bike spec stopping power. Providing
exceptional stopping power, these brakes also provide great lever feel and
" Huge 320mm rear disc is squeezed by a single piston caliper mounted below the
swingarm for a lower center of gravity and that customized "hidden look".
" Lightweight, 12 spoke cast aluminum mag wheels reduce weight and enhance
handling and styling. The front wheel is MT 4.00x18 while the rear wheel is a MT
5.50x17. Both are fitted with tubeless radial tires that provide excellent
traction and reduced rolling resistance.
" Two-piece seat design features a wide, flat profile for excellent rider
comfort. The passenger seat features a small lip at the rear of the seat
providing a secure feeling for the passenger.
