Suzuki SV650 1st Gen (1999-2002) Maintenance Schedule and Service Intervals

This is the maintenance schedule and associated service intervals for the Suzuki SV650 1st Gen, and also for the 1st gen Suzuki SV650S (the same bike with a bikini fairing). These bikes are affectionately known as the “Curvy” because of their more rounded styling vs the 2nd gen.

Here are all the generations of Suzuki SV650 or Gladius:

The Suzuki SV650 and SV650S variants were made from 1999-2002. They were mid-range motorcycles with a naked, exposed trellis frame (or a small bikini fairing), a 645cc water-cooled carburettor-fed V-twin engine, and minimal tech, all sold at an attractive price.

Basically the Suzuki SV650 and SV650S were considered to be the affordable alternative to the Ducati Monster. Although the SV650S, with its clip-on handlebars and bikini fairing, was more of an alternative to the Ducati Supersport 900 of the time.

The 1st gen Suzuki SV650 and SV650S was carburettor fed and had rounder styling than its replacement, the 2nd gen fuel-injected Suzuki SV650 in 2003.

What you need to service your 1st Gen Suzuki SV650

Servicing your SV650 is relatively easy as it’s naked (or nearly naked), and based on a carburettor-fed V-twin engine. You need basic motorcycle maintenance tools, as well as the following consumable parts.

PartSuzuki SV650 1st gen spec
OilSuzuki requires engine oil with JASO MA spec, or at least API SF/SG or SH/SJ spec. Many oils fit this. Suzuki recommends SAE 10W-40 weight Suzuki motor oil, so you can also use Motul 5100 10W-40.
Oil filterUse a Hiflofiltro HF138, which is a drop-in high-quality replacement.
Air filterUse a K&N air filter as a drop-in replacement, part number SU-6599.
Spark plugsThe standard spark plug is NGK CR8E. Should be gapped to 0.7-0.8mm (use a gapping tool).
Brake fluid/Clutch fluidSuzuki (like most motorcycles) requires DOT 4 brake and clutch fluid.
CoolantSuzuki only requires a coolant that’s “compatible with an aluminium radiator”. Most motorcycle coolants are, and so a Valvoline Zerex G05 is a fine option.
Chain maintenanceUse either Motul chain paste or a complete Motul chain care kit for frequent chain servicing.
GreaseAlways handy to have some lithium soap-based grease for external pivot points, like the kickstand.
Brake padsEBC double hardened brake pads are an excellent (and affordable) upgrade over stock. You need: FA229HH (front left), FA231HH (front right), and FA63HH (rear).

About the Suzuki SV650 1st Gen

Suzuki introduced the SV650 in 1999 as a budget entry in the emerging naked bike market — and it has been a winner ever since.

The first gen Suzuki SV650 was a minimal bike, with basic suspension and a simple engine, but it had just enough poke to be fun for a lot of riders. It’s still a favourite as a fixer-upper or a great first bike for people learning to ride (in the USA where there are no first bike power or weight restrictions). Riders of the SV pick it up as a first bike and then wonder why they ever have to upgrade.

The combination of light weight, rigid chassis, strong handling, and the small-ish V-twin’s strong mid-range torque is appealing to beginner and experienced riders alike. The SV650 immediately became popular, but American buyers wanted the sportier ‘S’ version that featured lower handlebars, higher foot pegs and a bikini fairing and windscreen, available only in the European and Canadian markets. American magazines ran articles describing how to import it into the United States. So 2000, Suzuki began importing the SV650S to the USA.

The first-gen Suzuki SV650 is powered by fundamentally the same platform as later gen SV650 bikes. The engine is a 645 cc liquid-cooled V-twin with an 11.5:1 compression ratio. It’s fed by 2 x Mikuni BDSR39 carburettors, and makes peak power of 53 kW / 72 hp at 9000 rpm.

The SV650 is, like other middleweight twins, focused on mid-range power rather than top-end grunt. So it can keep up with a GSX-R at up to freeway speeds, but beyond that, the four-cylinder bikes pull away.

But even so, the SV650 was (and is) relatively cheap, to the point where it became popular as a casual racer. It began dominating the “lightweight twins” racing class, beating bikes like the Ninja 500R and Honda NT650 which previously used to dominate it.

The suspension is the only let-down in a budget bike, but that’s to be expected. People often upgrade the fork on an SV650 either with cartridge emulators or suspension from a higher-spec bike, like the GSX-R600.

The SV650 has sold so well that it has been modified and re-sold in subsequent generations for decades now, culminating in the SV650X that’s being sold today.
