Looking for Final Drive Unit for Rocket 2005

[Tripps]

That is a great offer and price!
Unfortunately for @markur the Black Roadster diffs from ABS versions 2010 onwards will not fit earlier Rocket IIIs.
The earlier silver R3 diff does not fit later ABS versions and vice versa.
The old Boxer BMW diff swaps for gearing changes option does not exist for Rockets as there is ONLY one fitment for each series and I do not believe the final gearing changed but may be wrong.

I do have a low BMW R65 diff on my R100RS chair but probably not required for a Rocket as I doubt a chair worries the Rocket's torque output.

I have the entire r/65 on my chair

Are we all looking at the same thing?
Yep @1K9 , yours is worn with that step, your original prop shaft must be similarly worn too or worse.
In my discussions with @Mittzy it seems the prop shaft male teeth tend to wear more quickly than the receiving diff on used examples he has seen.


That Aussie one on eBay

The 'Rim side' of diff look similar.

Your one 1K9

I would have to remove the drive to see how the shaft looks.

The Ishrub shows is triangular with just an apex to grab onto. Mine is, I would estimate has 90% of the meat left. The output shafts are easy to find.

If it fits... 200 + shipping is a steal.

A Roadster Diff will fit all 2004 to 2018 - BUT you must also use the Roadster (or Touring) tail shaft.

Pic of a badly worn diff and drive shaft - also a good drive shaft - if your diff splines are worn your drive shaft will be also.
