Horsepower:
Approximately 105-108 hp @ 8500 rpm (depending on market regulations)
Torque:
Approximately 95-98 Nm (70-72 lb-ft) @ 6500 rpm (depending on market)
Fuel Delivery:
Electronic Fuel Injection (EFI) with Yamaha's Digital Fuel Injection (DFI) system.
Fuel Type:
Unleaded gasoline (91 octane or higher recommended)
Oil Capacity:
Approximately 4.0-4.5 liters (with filter change) - specific value to be confirmed in manual.
Oil Type:
Yamalube 10W-40 or equivalent API SG, JASO MA certified motorcycle oil - specific grade and specification to be confirmed in manual.
Oil Change Interval:
Typically every 5,000-6,000 km (3,000-4,000 miles) or annually, whichever comes first. Refer to manual for exact schedule.
Spark Plug Replacement:
Recommended replacement at approximately 10,000-15,000 km (6,000-9,000 miles). Manual will specify exact type and interval.
Valve Clearance Check:
Initial check at a lower mileage, then periodically every 10,000-20,000 km (6,000-12,000 miles). Manual provides specific tolerances and procedures.
Brake Fluid Type:
