Bouncing off the rev limiter in the S2000 happens so easily because the engine spins up to redline so quickly and smoothly (credit the light internals and low rotating mass). You're at 9000 RPMs before you even know it especially once you hit the VTEC transition at 6000 RPMs. The F20C has to be one of the free-est revving engines I've ever had the pleasure of owning.

A redline of 8500 RPMs with a fuel cut-off at 9200 RPMs is probably too unrealistic. That's a 700 RPM difference. Why limit the revs to only 8500 if the engine will go until the fuel is cut at 9200? Everybody will be going for those last 700 RPMs before shifting.

To get to a 240 HP rating, Honda had to go for the revs. I would imagine that they did everything they could to hit 9000 RPMs so they could get that 240 HP rating and probably just got in under the absolute maximum revs the engine could tolerate before blowing up. I think you'll see that with any super-high revving engine, the fuel cut-off is probably pretty close to the redline number.

The rev limiter is there to protect the engine. Redline always has some buffer built into it. 700 RPM is too much buffer.
