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.
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 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.
|Part||Suzuki SV650 (1st gen) spec|
|Oil||Suzuki 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, but I wouldn’t over-think this and use another popular high-grade oil like Motul 300V or Motul 7100.|
|Oil filter||Use a Hiflofiltro HF138, which is a drop-in high-quality replacement.|
|Air filter||Use a K&N air filter as a drop-in replacement, part number SU-6599.|
|Spark plugs||The standard spark plug is NGK CR8E. Should be gapped to 0.7-0.8mm (use a gapping tool).|
|Brake fluid/Clutch fluid||Suzuki (like most motorcycles) requires DOT 4 brake and clutch fluid.|
|Coolant||Suzuki 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 maintenance||Use either Motul chain paste or a complete Motul chain care kit for frequent chain servicing.|
|Grease||Always handy to have some lithium soap-based grease for external pivot points, like the kickstand.|
|Brake pads||EBC 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.
It 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. 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. In 2000, Suzuki began importing the SV650S to the USA.
The SV650 with its relatively low purchase price and excellent handling characteristics became popular with racers which prompted a rebirth of the “lightweight twins” racing classes across North America and the SV650 began outselling the Suzuki GS500, Honda NT650 and Kawasaki Ninja 500R, which previously populated the class.
The suspension is the only let-down in a budget bike, but that’s to be expected. People often upgrade them either with cartridge emulators
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.
