I was running a bit late to work today and had been riding the bike till speed limiter kick in for quite a stretch of highway, guessing about 10kms.. Just wondering when the speed limiter kick in, its just cut gas like we run out of gas, right? I see the RPM is no where near the red line and continue to wot till traffic ahead, with the limiter kick in intermittently. The engine handle fine and nothing out of ordinary happen. Why would honda put the limiter so low in the RPM range? Will prolonged limiter kick in hurt the engine?
at 180km/h its over.......bcos in japan is max. 180 allowed....or in first time was not planned the export in the whole world...
if i am right , with the first 3 gears/speeds you reach the redline bcos no 180 on speedo
Ohh, so its Japan limits...Anyway, I never drag gear till high rev in the low gearing before as i felt the bike will wobble a bit due to the strong pull... But funny thing is the rev cut came around 185km/h. Maybe to cater for the speedo error.
limit not on street...limit for the industry

To answer the question, it shouldn't bother the engine at all. Ride safe, though!
Spark cut

It is OK to hit the limiter once in awhile, but revving your engine that high on a long term basis may cause wear and damage.
In general, a hard limiter cuts either the spark or more commonly the fuel.
If it cuts the spark only, the unburnt fuel (HC) enters catalytic convertor, slowly plugging it on a long run. HC is the prime killer of catalyst, like i.e. frequent misfire...
Cutting fuel is a better option for engine, catalyst and environment.
When one says, "Spark cut", do you actually mean retard the spark timing? I think that is what is actually happening. Nevertheless, it is a crappy feeling.
Well, its a good thing my bike don't have a catalyst. But i think speed cut happen somewhere around 6k-7k rpm, isn't that consider acceptable low rpm for bike?

The limiter kicks in based on the speed that the motorcycle is traveling, not how many RPM's the engine is turning.
