Is 30,000km for a 600 OK?

Well, my RF900 has 66,500 MILES on it. I got it with 43,500 miles on the clock and no guarantees that the shims had been checked.

I haven't done anything about it since and I finally got around to having it checked last week. I would assume it hasn't had the valves adjusted in at least 36000 MILES - that's over 50,000 kms.

Not ONE of them was out of spec.

I change the oil every 3000 miles (5000 kms), keep it tuned mostly okay, replace the tyres when necessary and it keeps trucking on.

I aim to get at least 100,000 miles out of this one.

Had a 1999 CBR600FX with 45,000kms. No major issues and the engine is bullet proof. Then moved on to a 2005 ZX6R with 54,000km. Never missed a beat and ran flawlessly on our South Island tour earlier this year.. all 5000kms of it.

Both bikes were regularly serviced but that wasn't much more than an oil/filter change every 6000km and plugs every second service. At 45,000km shims need to be done but neither were that far out.
