Pride of ownership comes standard with every Stratoliner. Representing the pinnacle of the Star cruisers, the Stratoliner takes V-twin performance and character to a new level. Ready to roll with a quick detach windshield and backrest, the amazing Stratoliner is destined to set new standards by which all cruisers will be judged.
All new 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 head provides 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.
New 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 new heads also feature engine mounting points on each side of the head for increased chassis rigidity for exceptional handling.
All new, large size valve increase engine horsepower and torque. The new intake valves are 36mm in diameter (Warrior intakes valves = 34mm) while the new exhaust valves are 31mm ( Warrior exhaust valves = 28mm).
Specially designed valve train includes new short design intake and exhaust rocker arms that reduce inertia during high-rpm use.
New, high performance spec twin, crankcase-mounted, high-lift cams ensure strong torque and class leading acceleration.
All new 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.
All new 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 new pistons feature an Alumite coating to reduce friction. The overall piston height has been reduced by 2mm compared to the Warrior.
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.
Proposition 65 Warning: Operating, servicing and maintaining a passenger vehicle or offroad vehicle can expose you to chemicals including engine exhaust, carbon monoxide, phthalates, and lead, which are known to the State of California to cause cancer and birth defects or other reproductive harm. To minimize exposure, avoid breathing exhaust, do not idle the engine except as necessary, service your vehicle in a well-ventilated area, and wear gloves or wash your hands frequently when servicing your vehicle.
