BMW R NineT Pure (Euro 4) Maintenance Guide: Model 0J11 (2017-2020)
The BMW R NineT Pure (0J11), produced between 2017 and 2020, represents the essence of the classic roadster. While it features modern fuel injection and ABS, its heart remains the legendary 1170cc air/oil-cooled “Oilhead” boxer engine. As a Euro 4 compliant machine, it balances traditional mechanical character with modern emissions standards.
Proper maintenance is critical for preserving the longevity of this iconic engine and ensuring the safety of the rider. This guide provides a detailed walkthrough of the essential service tasks required for the 0J11 model, following the factory-recommended intervals and specifications.
1. Service Intervals and Maintenance Schedule
BMW recommends a service interval of every 10,000 km (6,000 miles) or once a year, whichever comes first. However, the boxer engine benefits significantly from more frequent oil changes if ridden aggressively or in urban stop-and-go traffic.
| Service Type | Interval (Distance) | Interval (Time) |
|---|---|---|
| Oil & Filter Change | 10,000 km / 6,000 miles | 12 Months |
| Valve Clearance Check | 10,000 km / 6,000 miles | N/A |
| Air Filter Replacement | 20,000 km / 12,000 miles | N/A |
| Spark Plug Replacement | 20,000 km / 12,000 miles | N/A |
| Gearbox Oil Change | 40,000 km / 24,000 miles | 2 Years |
| Final Drive Oil Change | 20,000 km / 12,000 miles | 2 Years |
| Brake Fluid Flush | Initial: 1 Year, then every 2 Years | 2 Years |
2. Engine Oil and Filter Change
The air/oil-cooled boxer engine relies heavily on its lubricant to dissipate heat. Using high-quality oil is the single most important maintenance task for the R NineT Pure.
Specifications:
- Oil Grade: SAE 15W-50 (Synthetic or Semi-Synthetic) API SJ / JASO MA2.
- Capacity: Approximately 3.95 liters (4.2 US quarts) with filter change.
- Oil Filter: BMW Part No. 11 42 7 673 541 (or equivalent like Hiflo HF164).
The Process:
- Warm the Engine: Run the bike for 5-10 minutes to thin the oil, then place it on a level stand (Paddock stand or center stand).
- Drain the Oil: Remove the drain plug (8mm Allen or Torx depending on the year) located at the bottom of the engine. Replace the crush washer (M16).
- Remove the Filter: Use a 76mm 12-flute oil filter wrench. Ensure the old rubber gasket comes off with the filter.
- Install New Filter: Lubricate the new gasket with fresh oil and hand-tighten. Torque to 11 Nm.
- Refill: Add 3.5 liters, run the engine, check the sight glass, and top up as necessary until the level is at the center of the red circle.
3. Valve Clearance Adjustment
Unlike the later liquid-cooled boxers, the Euro 4 R NineT uses a DOHC (Double Overhead Cam) system with shims under rockers (semi-hemispherical shims). While robust, clearances must be checked every 10,000 km.
Specifications:
- Intake: 0.13 mm – 0.23 mm
- Exhaust: 0.30 mm – 0.40 mm
Checking involves removing the cylinder head covers. Rotate the engine to Top Dead Center (TDC) for the cylinder you are working on. If the clearances are out of spec, you will need to replace the hemispherical shims, which are available in 0.05mm increments.
4. Final Drive and Gearbox Maintenance
The R NineT Pure features a shaft drive (Paralever). Neglecting the final drive oil is a common cause of expensive failures.
Final Drive Oil:
- Oil: 75W-90 Synthetic Gear Oil (GL-5).
- Capacity: Exactly 180ml (Do not overfill, as it can blow out seals).
- Interval: Every 20,000 km.
Gearbox Oil:
The gearbox on the 0J11 is separate from the engine oil. It requires 75W-90 GL-5 gear oil. The capacity is approximately 700ml-800ml. Fill until the oil reaches the bottom of the filler hole threads while the bike is level.
5. Air Filter and Spark Plugs
The air filter on the R NineT Pure is located under the fuel tank. This requires removing the seat and the tank mounting bolts to pivot the tank upward.
Spark Plugs:
- Type: NGK MAR8B-JDS (Two per cylinder).
- Gap: 0.8 mm (Non-adjustable).
- Torque: 12 Nm.
The 0J11 engine is a “dual-spark” design, meaning there are two plugs per head. Ensure you use a thin-walled 14mm spark plug socket to avoid damaging the cylinder head.
6. Braking System
The R NineT Pure (2017-2020) is equipped with Brembo 4-piston calipers at the front and a 2-piston floating caliper at the rear. ABS is standard.
Brake Fluid:
Use only DOT 4 brake fluid. Brake fluid is hygroscopic (absorbs moisture), which can lead to corrosion in the ABS pump. Flush the system every two years regardless of mileage.
Brake Pads:
Inspect pad thickness every 5,000 km. Replace if the friction material is less than 1.5mm thick. Sintered pads are recommended for the front to maintain the original bite and feel.
7. Battery and Electrical System
The 0J11 model uses a 12V 12Ah AGM battery (typically YTX14-BS). Because the boxer engine has high compression and a heavy starter motor, a healthy battery is vital.
- Tender: If not riding for more than two weeks, use a BMW-compatible CAN-bus charger through the accessory socket or connect directly to the battery.
- Terminals: Ensure terminals are tight and free of corrosion. Apply a thin layer of dielectric grease to prevent oxidation.
8. Torque Specifications (Critical Fasteners)
To maintain the structural integrity of your BMW, always use a torque wrench.
| Fastener | Torque Setting |
|---|---|
| Engine Oil Drain Plug | 32 Nm |
| Oil Filter | 11 Nm |
| Final Drive Drain Plug | 20 Nm |
| Final Drive Fill Plug | 20 Nm |
| Front Wheel Axle Bolt | 50 Nm |
| Front Axle Pinch Bolts | 19 Nm |
| Rear Wheel Bolts (Lug nuts) | 60 Nm (Tighten in a cross pattern) |
| Spark Plugs | 12 Nm |
9. Tires and Chain (Shaft) Care
The Pure (0J11) usually comes with cast alloy wheels, though some have optional spoked wheels. Tire pressures significantly affect handling.
- Front Tire: 120/70 ZR 17 (2.5 bar / 36 psi).
- Rear Tire: 180/55 ZR 17 (2.9 bar / 42 psi).
10. Conclusion
The BMW R NineT Pure (0J11) is a rewarding motorcycle to own and maintain. Because of its air-cooled design and exposed mechanicals, it is one of the more accessible modern motorcycles for the DIY home mechanic. By following this maintenance guide, you ensure that your Euro 4 Boxer continues to deliver its signature torque and character for decades to come.
