The Yamaha XJ 900 S Diversion is the larger, more powerful brother within the Diversion family and is known as a reliable mile-eater. With its 892 cc four-cylinder engine, shaft drive, and comfortable half fairing, this is a motorcycle built for long distances without worrying about chain maintenance. At
Motorparts-online.com, you will find a wide range of new and used parts for the Yamaha XJ 900 S Diversion, suitable for different model years and versions.
The Yamaha XJ 900 S Diversion: the big brother that can handle it all
The Yamaha XJ 900 S Diversion was introduced in 1994 as the successor to the original XJ 900 and remained in production until 2004. Beneath the half fairing sits an air-cooled 892 cc inline four-cylinder engine with eight valves, producing approximately 89 hp and 88 Nm of torque. Combined with the shaft drive and generous 22-liter fuel tank, this is a motorcycle built to cover long distances without hassle.
While the smaller XJ 600 Diversion was popular as an entry-level bike, the 900 S positions itself as a serious touring motorcycle. The additional power, wider seat for two-up riding, and stable handling make the XJ 900 S a bike owners grow attached to for years. Mileages of 80,000 km and more are no exception, and the engine continues to run smoothly without issues.

Difference between the XJ 900, XJ 900 S and XJ 900 GT
Over the years, Yamaha released several variants of the 900 Diversion. It is important to distinguish between them when ordering parts, as they are not always interchangeable.
The original XJ 900 was produced in the 1980s and formed the foundation for the later models. The XJ 900 S, introduced in 1994, is the half-faired version with improved seating comfort and a more modern appearance. The XJ 900 GT is mechanically the same as the S, but features a larger touring fairing and standard Krauser panniers. Technically, the S and GT are largely identical, but fairing parts, headlight, and trim pieces differ.
All 900 Diversion models share the shaft drive and five-speed gearbox, distinguishing them from the chain-driven
600 series. When ordering parts, always check the exact model year and version of your motorcycle.
Frequently sought-after parts for the XJ 900 S Diversion
The XJ 900 S Diversion is a robust motorcycle, but after years of use certain parts regularly require replacement. The air-cooled engine itself is extremely durable, but surrounding components need attention.
The dual exhaust system with two silencers is prone to corrosion, especially at the collector and exhaust headers. An original exhaust system in good condition is therefore highly sought after. The same applies to fairing parts: the half fairing, upper fairing, and side panels can easily be damaged in a fall and are difficult to find new now that the motorcycle is out of production.
Additionally, the fuel pump and fuel level sensor are known points of attention on the XJ 900 S. Over time, the level sensor can become inaccurate, resulting in an unreliable fuel gauge. A properly functioning used sensor is often a practical and affordable solution.
The front forks also deserve attention. The suspension of the XJ 900 S is known to be relatively soft, particularly at the front. Replacing fork seals and fork oil is a common maintenance task that noticeably improves ride comfort.
Shaft drive: low maintenance, but not maintenance-free
An important feature of the XJ 900 S Diversion is the shaft drive. Unlike the chain-driven XJ 600, the 900 does not require chain tensioning or lubrication, making it particularly suitable for riders who prefer minimal maintenance.
However, the shaft drive is not completely maintenance-free. The shaft oil must be changed periodically, and the universal joints and bearings can show wear at high mileages. Play in the drivetrain or a ticking noise when closing the throttle may indicate wear of the universal joint. At Motorparts-online.com, you will find the necessary parts to keep the drivetrain in top condition.
Performing your own maintenance
The XJ 900 S Diversion is an accessible motorcycle to maintain yourself. The engineering is straightforward, and the air-cooled engine keeps many tasks manageable. Changing the oil and oil filter, checking brake pads, and inspecting the fuel level sensor are jobs you can perform with basic tools.
On motorcycles with higher mileage, pay extra attention to the underside of the bike. The collector, swingarm, and fork tubes are areas where corrosion can occur, especially on bikes that have been stored outdoors. Also inspect the center stand, as years of supporting a heavily loaded motorcycle can cause cracks.
With the right parts and regular maintenance, your Yamaha XJ 900 S Diversion will remain a reliable long-distance machine, exactly as Yamaha intended.
Frequently asked questions
What is the difference between the Yamaha XJ 900 S and the XJ 900 GT?
The XJ 900 S and GT share the same platform, engine, and drivetrain. The difference lies in the bodywork: the GT features a larger touring fairing and comes standard with Krauser panniers, while the S has a half fairing. As a result, fairing parts, headlight, and windscreen are not interchangeable between the two versions.
How high can the mileage of an XJ 900 S Diversion get?
The air-cooled four-cylinder engine of the XJ 900 S is exceptionally durable. Mileages of 100,000 km and more are not uncommon, provided the motorcycle is properly maintained. At higher mileages, pay attention to common wear parts such as fork seals, bearings, and the condition of the exhaust system.
Why does the fuel gauge of my XJ 900 S Diversion show an incorrect reading?
This is a known issue with the XJ 900 S Diversion. The fuel level sensor in the tank can wear over time, causing inaccurate readings. Replacing the sensor generally resolves the problem.
Do parts from the XJ 600 Diversion fit the XJ 900 S?
No, the XJ 600 and XJ 900 S are technically very different motorcycles. The 600 series uses chain drive, has a different frame, and a smaller engine. Parts such as engine components, drivetrain parts, and frame elements are not interchangeable. Some smaller parts like mirrors or indicators may match, but always verify this based on the part number.
Is the Yamaha XJ 900 S Diversion suitable as a touring motorcycle?
The XJ 900 S is particularly well suited for touring. The combination of shaft drive, a generous 22-liter fuel tank, comfortable two-up riding, and a stable chassis makes it a popular choice among touring riders. With a set of panniers and a taller
windscreen, the motorcycle is fully tour-ready.
