Yamaha YZF-R6 1st Gen (1999-2002) Maintenance Schedule and Service Intervals

This is the maintenance schedule and associated service intervals for the Yamaha R6 1st Gen, made between 1999 and 2002, also known by its name the YZF-R6.

The original YZF-R6 was category defining and remains a classic — if you can find one in decent condition. It’s based on a 599 cc liquid-cooled 16-valve inline four-cylinder engine that makes quoted peak power of 88 kW (120 bhp) at 13000 rpm, and puts that down through a six-speed box and a chain drive.

For the 2001 model year, Yamaha significantly updated the Yamaha R6. It was still carburettor fed, but the motorcycle was significantly lightened (193 kg wet, down from 200 kg) and about 10% more powerful at the rear wheel. That’s a huge change! Yamaha also redesigned the bodywork as you can see in the pics below. The parts and maintenance schedule remain the same.

The thing that changed most significantly before the 2nd gen Yamaha R6 is the fuelling — these years were carburettor-fed, whereas from 2003 onward, the R6 received fuel injection.

Here are all the generations of Yamaha YZF-R6 for which we have maintenance schedules:

Engine oilYamalube yamaha engine oilYamaha 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 filterK&N oil filterMany R6 owners use K&N filter KN-303 for easy replacement (you can use a normal wrench).
Spark plugsNGK spark plugsYou need four spark plugs for the YZF-R6, NGK CR10EK (all models R6). On these earlier carburetted models, CR9EK is also OK.
Chain lubricantmotorcycle maintenance tools - motul chain pasteA really popular chain lubricant that’s low-mess and highly effective is Motul chain paste.
Cable lubricantmotorcycle maintenance - cable lubricantKeeping 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 greaseLithium soap based grease | Yamaha YZF-R6 1st Gen (1999-2002) Maintenance Schedule and Service IntervalsIt’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.

Maintaining Your Chain on the Yamaha YZF-R6

It’s important to maintain your chain on the R6, as on any chain-driven motorcycle, but particularly on the R6 as riding any bike hard is hard on the chain.

Use a good-quality chain lubricant like Motul chain paste, or a Motul chain care kit which comes with a couple of handy tools to maintain the chain.

Yamaha recommends you follow the following chain maintenance schedule every 500 mi / 800 km and after washing the motorcycle, riding in the rain, or riding in wet areas.

Chain maintenance item
Check drive chain lubrication condition, lubricating if necessary (Motul chain paste)
Check drive chain slack, alignment, and condition, adjusting / replacing if necessary

Naturally, if you track or race your R6, then attend to your chain more often.

About the Yamaha R6 1st Gen

Red and White Yamaha YZF-R6 on track web

The 1st gen Yamaha YZF-R6 was ground-breaking for the 600 class. People riding it described it being like a drug.

The original YZF-R6 was and remains one of the most iconic sport bikes of the modern era.

Motorcycle.com says it best: Never mind the bollocks, we’ll get right to the point: The Yamaha YZF-R6 kicks ass. It is one of the most feral, thrilling, heart-pounding motorcycles we’ve ever ridden. Yeah, yeah, don’t many journalists use over-the-top superlatives in order to mollify manufacturers and help pay for the ad guy’s mortgage? Yes, it happens, but this time we really mean it.”

The Yamaha R6 1st gen is carburettor-fed. It’s based on a 599 cc liquid-cooled 16-valve engine, just like all its successors, but it’s the only generation that’s carburettor fed.

It’s quite peaky in power, making peak power of 88 kW / 120 hp at a fairly high 13000 rpm. But the later model R6s all made their power even higher up, so you could say that compared to later models, the first gen R6 is quite torque-forward! Still, the powerband kicks in at 6000 rpm. Redline on the original YZF-R6 is a sky-high 15500 rpm.

Ride gear for the first-gen Yamaha YZF-R6 is very advanced. Front suspension is a 43mm inverted telescopic fork that’s fully adjustable, and the rear fully adjustable shock has a piggyback reservoir.

Front brakes are twin 298 mm discs and 4-piston calipers.

The original YZF-R6 is very reliable, as are most liquid-cooled Yamaha motorcycles. If you keep the oil changed and the coolant and brake fluid fresh, it’ll last until some of the exterior parts corrode or until you crash it. The main things people complain about on older models are corroded bolts, brackets, and fasteners. But atmospheric moisture and whether or not it has been kept clean play a role in how fast that happens.

Since more than two decades have passed since the first Yamaha R6 models rolled off the shelves, make sure you have a long list of items to check before buying one used.

Things to check would include regular maintenance items, including whether hoses have been replaced, fluids are up to date, and whether the valve clearance check has been done according to the schedule every 26600 miles / 42000 km.

But aside from that, also look at the suspension units. On older bikes, it’s not uncommon for seals to fail. Replacing them is pretty laborious.

Finally, since the Yamaha R6 1st gen is carburettor fed, make sure that the carb works and that the jets are both not blocked and are suited to any upgraded intakes and exhausts.

The next generation Yamaha YZF-R6 had the benefit of being fuel-injected. Easier to dyno-tune, and less likely to gum up.
