Specific Maintenance Notes and Considerations

While the tables provide a clear framework, certain aspects of R 1250 RT maintenance warrant further explanation to ensure thorough understanding and optimal care:

Coolant System: BMW uses a 'permanent' type of antifreeze (OAT or HOAT) in the R 1250 RT, which is designed for a long service life and does not have a specified replacement interval in the manual. The primary recommendation is simply to check the coolant level regularly. However, some mechanics and dealers suggest a coolant change every 3-4 years as a preventative measure, especially if you observe the level consistently declining or if the coolant appears discoloured. While not strictly mandated, this can help maintain the cooling system's efficiency and prevent potential issues.

Universal Shaft Maintenance: Interestingly, while BMW updated the manuals for other R series bikes (like the GS) from 2023 onwards to include checking and lubricating the universal shaft every 20,000 kilometres (12,000 miles), this specific recommendation was not explicitly added to the R 1250 RT manual. However, considering its vital role in power transmission and the ease of the task, it is highly recommended to incorporate this check and lubrication into your routine at the 20,000 km / 12,000 mile intervals. Furthermore, for some other models, BMW suggests replacing the universal shaft – depending on wear – at the 60,000 kilometre (36,000 mile) mark. While not specified for the RT, it's a point to consider regarding the estimated lifetime of this component. Many universal shafts, of course, last significantly longer with proper care.

Running-In Check: The initial 'running-in' service, typically performed after the first few hundred miles, is crucial for a new motorcycle. This check is usually carried out by the BMW Motorrad dealer as part of the purchase agreement and ensures that all initial adjustments and tightening torques are correct after the engine's break-in period. It's generally omitted from the standard owner's maintenance schedule as it's a one-off dealer responsibility.

Continuing the Schedule: The provided maintenance schedule outlines intervals up to 40,000 km / 24,000 miles. Beyond this point, simply continue to follow the pattern shown. The intervals repeat, ensuring continuous care for your motorcycle throughout its lifespan.

Time or Distance: Always remember the golden rule: follow whichever interval comes first, be it the mileage or the time period. For example, if you only ride 3,000 miles in a year, you should still perform the annual service, including an oil and filter change, even if you haven't reached the 6,000-mile mark. This accounts for the degradation of fluids and components over time, regardless of distance covered.

What You'll Need for DIY Servicing

For those confident in performing some of the maintenance tasks themselves, having the correct parts and fluids is essential. Using genuine BMW Motorrad recommended products ensures compatibility and optimal performance. Here’s a list of key consumables for your R 1250 RT:
