General topics » Oil change in bevel gears rear - interval

My 1250RS had its PDI in May 2021, running-in check in June 2021 (632 miles), 1st annual service in June 2022 (2577 miles) and 2nd annual service today (6484 miles).
The Riders Manual maintenance schedule shows that the oil should be changed in the bevel gears every 24 months or every 20,000 km. I was expecting the bevel gear oil to be changed today. However, I was told that it was done at the running-in service and does not need to be done until the next annual service. Does that sound right?
I am about to go on a ca. 3K miles continental trip, so am a little concerned.

I change my bevel oil every year no matter what the mileage, it's 180cc so one longlife 1litre bottle covers 5 years it's so easy to do on later units.
No need to remove wheel and drop the unit, drain and fill plugs are easy access.

Having had a 'filled for life' R1200st bevel failure, which then cost £400 'off the bike' for overhaul it now seems an easy option to take.

I did work out that "missing those service oil changes" for 30,000 miles probably saved the same £400 from invoices but lower for home servicing and "oil is cheaper than metal"

I know originally it was 'filled for life/no need to change' and declined on many intermediate services but then bmw changed it to more often on those models!

My '23 R1250RS had the rear end oil changed at the initial service along with the engine oil and filter. I put enough miles on that I don't worry about annual changes except for the brake fluid.

I, too, had a "filled for life" rear end on my '05 ST. My local tech told me at the time- "When it blows up, it's life is over!"
We decided to to change the oil regularly. The downside is that the original rear ends had no fill port, only through the ABS sensor hole.

Gee! You’ve had to change rear hub oil on a 2023 bike already?

Wow!

I’ve done it only 3 times (I think) on a 2015 bike.

I know it’s only 180 mil but I’m a canny Scotsman so minimum appropriate maintenance is my goal.

ps - I spent my working life in a Maintenance World where Condition Based Maintenance was the smart way to do things 😀

I do mine annually at every service. As has been said, it's easy and relatively cheap. I also fitted a stronger magnet equipped drain plug recently.

Every 2 years is the stated interval and I wouldn't worry about them counting the running in service in that.

Having pointed-out the service interval to the dealer (?!), I’m pleased to say the bevel gear oil change will be done shortly FOC.

It gets changed at the 600 mile service.

Odds are the oil is good based on mileage, BUT the rear is not a sealed system, so for the risk of moisture intrusion, it should be changed every 2 years.
