Oil leak! Uh-oh.

Hi Folks,

 

I have a 2010 1200RT with 104,000kms on the clock. Just noticed a clear oil dripping from the shock knuckle right in front of the rear tire. I'm no mechanic, but i'm assuming the shock is toast. I can't think of anything else that would be dripping fluid in that area of the bike.

I rode yesterday, and was thinking the ride was a little harsher than usual but put it down to road conditions, no ‘pogo-sticking' yet, but maybe that's because only a small amount of fluid has leaked? Thoughts?

Could just be a small o-ring or fitting seal. I try to convince myself that broken things need the most inexpensive repair until the demon comes and takes the wallet out of my back pocket.

Does your bike have ESA ?

(Electronic Suspension Adjustment)

If so, the shocks are not known for incredibly long life and are DTW*

With a combined 190k miles on two ESA equipped bikes, that's news to me.

2012 R1200RT 44,000 miles

 

I've just had the same problem today. But it has also coincided with low brake fluid level in the FRONT reservoir. Haven't had a chance to check yet, but are the front and rear master cylinders linked? ie a leak at the back take fluid from the front?

The brakes are linked but the master cylinders are separate so a leak in the back brake won't effect front master cylinder fluid level.

 

But the front brake master cylinder hydraulic circuit does go back as far as the ABS module under the fuel tank so it's possible that you could have a leak in the ABS module (or line at that point)  that leaks down on the engine then out towards the rear of bike.

 

Also, keep in mind that worn brake pads can also cause a low looking reservoir fluid level.

 

What type of fluid are you leaking?

Sorry for the delay Dirtrider,

Been an expensive week.

Rear shock was toast, central rod is also worn. Mechanic is rebuilding it. The front master cylinder seal was weeping, Front right caliper was leaking at the piston and the front left caliper was seized solid. 

Managed to get a pair of good condition calipers on ebay, shock is being rebuilt, front discs are being replaced and some new tyres as well.

Thanks for the follow up. Wow, that does sound expensive.  That seems like a lot is wrong for a  2012 1200rt  with only 44,000 miles  on it. Was that by chance a flood area bike?

Bad luck Axabmw. How odd for all of these issues on a low mileage bike. Was the suspension and the brakes not working at some point? From your original message, it all started with oil weeping, not issues with braking or suspension. Keep us in the loop. Do you have a history of the bike?

It's not a flood area bike, but lives 75 yards from the sea. The salt air seems to be very hard on bikes. My Honda NT700 aged very quickly as well.

Unfortunately working 70+ hours a week doesn't leave a lot of time for TLC.

Had bike nearly three years, had 4,000 miles when I got it. Serviced it myself or use a local private BMW specialist.
