I hear what you're saying BN - but he revalved the forks on my DRZ and fitted a new spring to the shock - haven't had a moments problem.
I would like to know the reasons behind the failure of Michnus's shock.

Give superfoxi a visit. He just redid my Zook shock and forks. Very good service :)
I crash test all of my safety gear. Do you?

Not that i want to be nasty but most shock failures are caused by either normal wear & tear, poor suspension setup or failure to activate common sense before hitting the start button.

I don't think I have to explain normal wear and tear.

Poor suspension setup: Your shock is undersprung and bottoms out frequently. This eventually destroys the shock mechanically.

A shock absorber by design converts kinetic energy into thermal energy.
If you ride your bike hard enough youi will get to the point where the shock produces more heat than it can dissipate. It overheats and blows.
Contributing factors are riding style, load on the bike and suspension design.
If you ride the bike at 130 over a badly corrugated road because you think that's best and the bike flies over the corrugations: You WILL blow your shock.
If you carry a lot of luggage, ride two up and ride hard you WILL blow your shock.
Bikes with hard springs, short stroke dampers and a high transmission rate between the rear axle travel and damper travel are more susceptible than systems with lower transmission rates and long stroke dampers.
Dampers with external reservoirs are less susceptible to failure due to their larger surface area to dissipate heat.

You can break everything if you just try hard enough and long enough ::)

As for the OP question and DRZ rear shock: As far as I remember the DRZ has quite a good quality rear shock. As long as it has not been destroyed by riding it without oil I'd say rebuild.

Thanx for all your input dawgs. I found a guy here in PE with loads of shock rebuilding experience. I guess running abot 90Kg with kit
and a further 20Kg of luggage does take its toll. The DRZ is such a sweet handling machine over the rough stuff, its hard to not keep the throttle pinned.
Cheers
