Rear Shock Service Intervals?

Hi guys

I ride a 2009 TE 610 with just under 20 000 km on the clock. AFAIK, it has the Marzocchi rear shock. I recently noticed some unusual movement on the rear wheel. I'm suspecting the rear shock is the main culprit.

I've had the bike for roughly 5 000 km and I don't think the shocks have been serviced prior to me taking ownership.

My KTM 950 S rear shock went a good 60 000 km before I had it serviced.

So my questions are: how often do you service your rear shocks?

Actually, the rear shock is Sachs, not Marzocchi.

Every 2-3 years. I ususally have them checked out every second front fork seal replacement as a guide.

PS check out your linkage/swing arm first it may have a stuffed or dry bearing .

Looks like the bearings are still good. I'll re-grease before fitting.

I've also taken the shock out and dropped it off for a service.

I was shocked at the condition of my linkage and swing arm bearings on my 2009 at about 16 000km and serviced and rebuilt the dog bones etc. Peace of mind. Check the Heim joint on the shock as well.
