2012 Yamaha Stratoliner Deluxe Features and Benefits

ENGINE

1854cc, 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 ensure 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 utilizes a pent roof combustion chamber design and features an oil passage near the exhaust valve seats 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 higher rpm use.

Twin, crankcase-mounted, high-lift cams ensure strong torque and class leading acceleration while also lowering the centre of gravity.

Mechanical centrifugal decompression mechanism located in each of the exhaust camshafts ensures fast, easy starts. This system 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 reduced vibration and 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 underside 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 the rider.

Compact design dual engine counterbalancers reduce vibration for exceptional rider and passenger comfort.

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

Mikuni 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 spent exhaust gases 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 heads ensure 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 fuel 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 (T.C.I.) 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 throttle.

High-performance, 2-into-1-exhaust system features large diameter header pipes for maximum flow. The single muffler contains a 3-way honey comb matrix catalyzer 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 to 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 very stylish.

Low-maintenance belt drive system not only significantly reduces 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.

CHASSIS / SUSPENSION

Aluminium, 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 stressed member for added rigidity.

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 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 aluminium, 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 (4.3").

Powerful dual 298mm floating front discs are squeezed by ultra rigid, 4-piston, monoblock calipers providing sport-bike spec 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 polished 12 spoke cast aluminium 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.

The front and upper rear engine mounting brackets have been revised and strengthen the engine's function as a stressed member of the chassis.

The head pipe (steering head), wheelbase, caster and trail dimensions are optimized to accentuate the engine and frame characteristics. The benefit is incredible turning ability and quick, stable handling.

Removable rear sub frame is constructed of square-section, lightweight aluminum pipe. Its detachable design allows easy access when servicing rear suspension components.

Revised lightweight, tapered, aluminum swingarm is produced using "hydro forming", a special method that uses high pressure water to form shapes. The swingarm design provides great overall "balance" with the frame for precise cornering, excellent traction and a light handling feel. The end portion (chain adjuster area) has been modified and the rigidity increased.

Cast aluminum upper and forged aluminum lower triple clamps. The new cast upper clamp features a 50% increase in rigidity for improved handling.

Fork offset has been decreased from 25mm to a 22mm offset. This increases the trail dimension and provides excellent stability.

Revised 48mm, adjustable, inverted, Kayaba, "Speed Sensitive", cartridge fork features a twin-chamber design, meaning the damper unit is in a separate structure which prevents aerated fork oil from entering the inner damper assembly and degrading its damping abilities. Since the inner damper is pressurized, it also prevents air bubbles forming in the oil.

For 2012 the fork modifications include a weight reduction to the internal cylinder head, tank and spring guide (these are fork internals … not engine internals). The outer tube shape is revised and is now the same as the YZ450F

Front fork adjustments include: 20-way compression damping and 20-way rebound damping. Optional fork springs are available through Genuine Yamaha parts.

The 48mm inverted KYB fork also features a Transfer Control Valve (TCV) system. The TCV enhances the damping force of the inner damper from mid stroke to full stroke and improves bottoming characteristics. The benefit of TCV is more precise control throughout the full stroke. The TCV is located on the upside of the spring and its function is controlled by piston speed, not piston position … hence the term "Speed Sensitive fork".

Front and rear suspension settings have been modified to accentuate the engine and frame changes.

The combined benefits of the revised frame, fork and fork offset provides less front - rear pitching and excellent stability when exiting a corner.

Front wheel travel is 300mm or 11.8"

Large "wrap-around" plastic fork protectors provide excellent lower fork tube protection. The "self-supporting" design reduces friction for smoother fork operation.

Revised Monocross link rear suspension system features a fully adjustable Kayaba, piggyback shock which features separate adjusters for high- and low-speed compression damping. Adjustments include: spring preload, 20-way rebound damping, 20-way low-speed compression damping and 2 turns of high speed compression damping.

The revised shock uses a new 16mm diameter piston rod. Kashima coating is used in the shock body and sub tank to reduce friction and improve suspension performance during a long moto. The Kayaba shock utilizes a full rebound oil lock system for excellent suspension function and great ride quality.

Rear wheel travel has increased from 307mm (12.1") to 317mm (12.5").

250mm floating front wave-style disc reduces weight and improves heat dissipation. It is squeezed by a compact Nissin twin piston caliper.

245mm rear disc brake features a lightweight "wave-style" disc and a single piston Nissin caliper.

Compact, lightweight rear master cylinder is an integrated design (fluid reservoir is integrated into the top of the master cylinder) for strong stopping power with excellent feel and control.

Pro Taper handlebar provides excellent strength and durability. Foam handlebar pad is included.

Adjustable handlebar clamps offer a total of 4 different handlebar positions with an adjustment range of 30mm, to suit a wide variety of riders.

Eye catching, compact body work enhances the lightweight feel and look of the YZ250F. This "minimal" bodywork is a flat design, allowing fast, easy rider movements. The ergonomics provide a natural and roomy riding position. The body has been designed to maintain it good looks throughout the life of the machine.

The lightweight, plastic resin 6.4 litre fuel tank compliments the chassis and its location helps to centralization tank mass. Its compact design allows excellent rider mobility.

Revised seat material reduces weight and improves rider comfort. The seat surface texture has been designed to give a grip when needed, yet still allow easy rider movements. The seat cover resists clogging with dirt or mud to ensure long lasting good looks.

Lightweight, 21" front and 19" rear Excel rims provide exceptional durability and help reduce unsprung weight for optimal suspension performance and handling.

Rear wheel assembly uses a large 25mm diameter axle and the rear hub features a second bearing on the sprocket side for increased rigidity and durability.
