Rev Limiter

Hey guys, I would like some clarification on the rev limiter for the 17+ model.

So, #1, is the rev limiter hard set at 13k? Any over-rev?
2nd: With Honda's specs for max HP at 13K, if the rev limiter is set at 13k, it does not make sense?
So, from reading posts here, the US bikes are severely crippled and the max power is at about 10.2K? So, at the track you guys still shift close to the limiter?

I will find out some time in DEC at the track (or sooner on the street, although due to my job's nature cannot have a ticket )

The limiter is set at 13.8 , but with a NA spec bike the bike really falls flat on its face above 10k.

13.8 is Euro/Australia or post Woolich flash. Stock US rev limiter is 13,200rpm.

Thanks both. That’s screwed up. So I would guess the max HP at 13K is for the Euro bikes?

Bizarre, I looked at my original file in Woolich and it said 13,800. Maybe I got something swapped around, who knows. Still feels like it hits a brick wall at 10, though.

No, Woolich inject the Euro rev limit in the default data file as the engine is able to manage 13.8 stock.
Think about it, you never see the data you directly read on/from your ECU, you only read the data Woolich presents you from their database.

So when I was selecting options for my Woolich flash (US bike), one was to raise the rev limit - but I believe that was "not recommended" for unmodified engines. Did I miss out on some performance gains by not choosing to do that? I'm more of a "play it safe" guy when it comes to that sort of thing, I have no intentions of tracking it or getting into any races on the street.

There is no need to raise the rev limit if you re not going to rev past 13 grand, and on the stock bike you really will be flogging it as there is nothing to be had after 11,500 anyway.

That is odd, here in South Africa my stock 17+ model limits at 16 500 RPM. Would the differences be related to regional emissions regulations?

Hey swaer, jy meen seker 13,500rpm ne?

What is the part number on the ECU? Sal help determine wat se region die bike vandaan kom.
