Yamaha R1 2nd Gen (2002-2003) Maintenance Schedule and Service Intervals

2003 Yamaha YZF-R1

This is the maintenance schedule and associated service intervals for the 2002-2003 Yamaha YZF-R1, also known simply as the 2nd Gen Yamaha R1.

This maintenance schedule is for the second generation Yamaha R1, released in 2002 and kept the same for 2003. The maintenance is nonetheless very similar to that for the first generation R1.

The main difference between the second gen and the first gen is that the 2002+ Yamaha R1 has fuel injection.

Purists will also be annoyed that the 2nd gen Yamaha R1 has slightly more muted design… gone is the red seat of the 1st gen!

What you need to service the 2nd gen Yamaha R1

To service the 2nd gen Yamaha R1, you may need the following consumables.

Part/consumableImage2002-2003 Yamaha R1 specification
Engine oil Yamalube yamaha engine oil Yamaha recommends using their own motor oil, which is affordable and good. Yamalube 10W-50 covers a huge range of operating temperatures, from below freezing to above 100 degrees F / 40 degrees C.
Oil filter K&N oil filter Replace every 2nd oil change. Many 2nd gen R1 owners use K&N filter KN-303 for easy replacement (you can use a normal wrench).
Spark plugs NGK spark plugs You need four spark plugs for the YZF-R1, NGK CR9EIA-9 for the 2002-2003 Yamaha R1
Air filter air filter generic pic Use K&N air filter YA-1002 for the 02-03 model.
Chain lubricant motorcycle maintenance tools - motul chain paste A really popular chain lubricant that’s low-mess and highly effective is Motul chain paste.
Coolant Zerex valvoline coolant Valvoline Zerex G05 meet’s Yamaha’s requirements for an ethylene-glycol anti-freeze with corrosion-prevention properties.
Cable lubricant motorcycle maintenance - cable lubricant Keeping good clutch action depends on having a well-lubricated chain. You can use engine oil, but Protect All Cable Life is an affordable and well-used staple of maintenance.
Mechanical grease It’s important to grease moving parts, like the sidestand and sometimes bearings, to keep them from getting notchy or seizing. Valvoline moly-fortified grease meets a lot of needs.

2002-2003 Yamaha R1 2nd Gen Maintenance Schedule

Below is the maintenance schedule for the 2nd generation 2002-2003 Yamaha R1.

The periods below are given in a distance or time interval — you should observe whichever comes first.

Maintenance schedule notes

  • Mileage is from the US manual and kilometre intervals are from the European/Australian manual. The European Yamaha R1 manual had different service intervals. Rather than every 4K mi (7k km), the same items were every 10K km (roughly 6K mi). On the other hand, valve clearances in the Europe manual were every 40,000 km (vs 26.6K miles in the US version).
  • After the end, continue repeating every two service intervals.
  • Yamaha recommends only servicing the chain, changing the oil, and greasing major points yourself, and leaving everything else to the dealer
  • Chain: Check, clean, and lubricate chain every 600 mi (1000 km) or after washing the motorcycle or riding the rain
  • Air filter
    • This model’s air filter is equipped with a disposable oil-coated paper element, which must not be cleaned with compressed air to damaging it
    • The air filter element needs to be replaced more frequently when riding in unusually wet or dry areas
  • Hydraulic brake system
    • After disassembling the brake master cylinder and calipers, always change the fluid. Regularly check the brake fluid levels and fill the reservoirs as required
    • Every two years replace the internal components of the brake master cylinder and caliper and change the brake fluid
    • Replace the brake hose every four years, or if cracked or damaged.

The maintenance for the 2002-2003 Yamaha R1 is broken into two sections: periodic maintenance for emission control systems, and general maintenance and lubrication.

Periodic maintenance for the Yamaha R1 2nd gen

About the 2002-2003 Yamaha R1 2nd gen

After four years remaining basically unchanged, Yamaha added fuel injection for the 2003 Yamaha R1.

The fuel injection worked like a carburetor by employing a CV carburetor slide controlled by vacuum created by the engine. With a similar power output to the 2000-2001 bike, the engine remained largely the same.

The fuel injection on the early R1 2nd gen was reportedly amazing. Early fuel injection fuelling wasn’t great on other racing motorcycles, but the early R1’s fuel injection was smooth and predictable, making it a decent city rider.

One notable improvement was the use of new cylinder sleeves of a high silicon content alloy containing magnesium that minimized heat induced distortion, reducing oil consumption.

Also in 2002, Yamaha released the newly developed Deltabox frame, which, with its hydro formed construction, reduced the total number of frame welds.

For 2003, the only change was fitted hazard warning lights and dipped headlights, which stay on all the time the engine is running.
