BMW R1200RT Transmission Oil

Use SAE 75W-140 standard transmission fluid for lubricating the 6-speed gearbox of the BMW R1200RT.

The gearbox has a total oil capacity of 700 ml (0.7 liters) for smooth shifting.

Separate final drive containing gears and shaft to rear wheel holds 180 ml (0.18 liters)

Transmission oil should be changed every two years or every 40,000 kilometers. 

Experienced riders recommend replacing a BMW’s transmission fluid every 30 to 60 thousand miles.

BMW R1200RT Transmission Comparison to Rivals

The Honda ST1300 features a 5-speed cassette-type transmission with lower gear ratios than its predecessor for quicker acceleration.

Its hydraulically actuated wet clutch enables smooth gear changes.

The ST1300 redlines at 9,500rpm with peak horsepower of 111hp at 7,750rpm.

The Yamaha FJR1300 utilizes a compact 6-speed transmission and hydraulic clutch system.

Delivering max power of 141hp at 8,000rpm, its closely-stacked 6th gear keeps rpm low for effortless cruising while maintaining rapid acceleration.

The BMW R1200RT also houses a 6-speed gearbox with a wet, anti-hopping clutch for precision shifting.

Its flat torque curve peaks at 125Nm at 6,500rpm, propelling the bike to 262km/h (163mph) top speed.

Tall 1st gear provides vigorous acceleration from a standstill up to 91km/h (57mph).

All three bikes achieve highway speeds by 2nd gear, with maximum engine rpm kept low for fuel efficiency thanks to their 6th gear overdrive capabilities. Precise gear ratios balance low-end grunt for stoplight getaways with relaxed long-distance cruising.

BMW R1200RT Transmission Problems

The universal shaft and output shaft bearings of the Final Drive have garnered a reputation for premature failure.

R1200RT transmission makes noises when the universal shaft and output shaft bearings wear out sooner than expected.

Premature wear on these components can escalate to final drive failure, though fortunately, warning signs often manifest before reaching a critical stage.

Get the motorcycle inspected at the dealer as soon as you hear any unusual sounds from the engine.

BMW R1200RT Transmission Reliability

Clutch-less shifting is very smooth on the BMW R1200RT. Some riders say that the transmission has a minor clunk in first and second gear.

Some years of the R1200RT are more prone to final drive failures than others.

The cost of having a dealer repair is significant. The gear shifts aren’t as smooth as in a Honda motorcycle.

BMW R1200RT Maintenance

BMW specifies that the final drive (FD) gear oil should be drained and refilled with fresh SAE 75W-140 lubricant every 2 years or 20,000 km, whichever comes first.

Additionally, the 6-speed transmission gearbox oil should be completely changed out with new 75W-140 fluid once every 2 years or after traveling 40,000 km.

BMW R1200RT Transmission Maintenance Costs

It costs around $50 to replace 75W-140 Final Drive oil every 2 years or 20,000 km, whichever comes first.

You need $15-20 worth of 75W-140 Final Drive oil to replace gearbox oil every 2 years or 40,000km.

BMW R1200RT Transmission vs Fuel Efficiency

R1200RT transmission’s efficiency can be emphasized by the speeds achieved at 1000 RPM across gears, making the R1200RT ideal for both city speeds and long highway rides.

The gear ratios, ranging from an extra-tall first gear for strong acceleration to closely stacked higher gears, provide a versatile range suitable for various riding conditions.

The wide 6-speed transmission allows for a broad speed range, from 91 km/h (57 mph) in first gear to a top speed of 262 km/h (163 mph) in sixth gear, showcasing a balance of low-end torque and high top-speed capabilities.

Comparatively, against rivals like the Honda ST1300 and Yamaha FJR1300, the BMW R1200RT stands out with its 6-speed gearbox, anti-hopping clutch, and a flat torque curve, providing a unique blend of power and efficiency.
