Looking for a motorcycle capable of long distance touring but
with style and abilities for
intown boulevard cruisin,
I decided to find a Japanese made Star Stratoliner. This happens
to be the largest air cooled engine available by a major manufacturer, 1852cc,
113 cu. in.
With an aluminum frame and swingarm, this is one
agile cruiser style motorcycle.

FEATURES:
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 (Warrior intakes valves = 34mm) while the exhaust valves are 31mm ( Warrior exhaust valves = 28mm).
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.
"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.
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
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.
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.
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 EFI
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
heads to ensure 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 liter 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. The side mounted air filter common on the Road Star series has been
eliminated giving a cleaner look at the engine's cylinders on the right side.
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-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 changes.
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 V-twin powerplant.
Smooth-shifting, 5-speed
transmission features optimized gear ratios for strong acceleration and relaxed
cruising at highway speeds.
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 desired.
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.
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 Stratoliner's eye catching styling.
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
blacked-out 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 adjustability 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 (4.3").
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 feedback.
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.
51w
/55w high efficiency Irradiation headlight. This is a 2 bulb design, one for
low beam and one for high beam. The unique headlight body compliments the
"neo-streamline" styling.
Steel fenders front and
rear can be easily customized or painted to suit personal preferences. The
front fender features a classic fender stay.
Flangeless teardrop style
fuel tank offers 14 liters of capacity. This is the first flangeless tank used
on a Yamaha cruiser. There are no welds visible, providing that custom look.
The total fuel capacity is 17 liters thanks to a 3 liter sub tank located low
in the frame below the seat. A high pressure electric fuel pump with quick
connect fittings provide fuel to the EFI system.
Large 1.25" diameter
handlebars. All electrical wires are hidden inside the handle bars for that
clean custom look. Selected meter functions can be controlled by buttons on the
back of RHS handlebar switch.
Fuel tank mounted
instrument panel. This panel has the classic "grand
father" clock image. Just below the large analogue speedo is an analogue tach and
fuel gauge. Other functions include digital odometer, dual tripmeters,
fuel reserve trip counter and clock. Background illumination can be adjusted to
suit personal preferences.
Super quick detachable
windshield can be removed without tools. The new Stratoliner
is a true "convertible" similar to the Royal Star Tour Deluxe. The
windshield locks into place with the ignition key for added security.
Super quick detachable
chromed passenger backrest can be removed in seconds without tools. The
backrest locks into place with the ignition key for added security.
