We will not get an explanation here. Maybe someone closer could shoot Dave an e-mail and ask for clarification?

Ugh that explains the issues under braking. I was afraid that was bottoming out. Thanks for the info. I'll be working on this next track day

Hmmm.....the service-manual describes the fork height - page 4-88.

Manual says 2 lines has to be visiable on the fork tube, but my bike was delivered with only 1 line visiable.
So it might be too high set from the factory.

R1 2015 on track, Aprilia Shiver on road.

Hmmm. Mine was set at 2 lines. Tire pressures were too high of course. Going to check/set sag this weekend. 520 chain swap and 2 up in back ended up extending the wheelbase a bit over 1/4 inch so I'll be curious to see what if any compensation is needed there.

I'm new to the R1. Is the electronic steering damper similar to the Honda CBR1K in that it increases damping with bike velocity? I just Flashed the bike and left the steering damper 'ON'. Recommendations on turning it 'OFF'? Realizing of course that most people go to the aftermarket at some point anyway.

BTW, that manual is just a bit under $100. I think I'm building my dealers retirement fund

Mine is set at 2 lines as well. Adding teeth to the back sprocket shortens the wheelbase not extends it.
The steering damper is speed dependent and it has a map that can be edited to suit your riding. It provides more stability at high speed but in the fast corners it could get hairy as the bike can be very hard to turn so for the track work you will need to edit it. I would not recommend switching it off altogether because a bad experience with Gixer that went into a tankslapper at 90km/h going through double railway crossing
I got an Australian manual for $60 from a dealer. Just over 67Mb. If someone knows how to link it for a download I am happy to share it.

hey thanks man for the manual. works great.
as per your question on number of lines showing on the fork...the 4-88 manual diagram looks like two lines showing but on my bike its one line. I don't count the fork cap as a line. Here is a pic of mine showing as delivered 1 line showing.

btw after riding the bike on track I can see no reason to lower the front anymore than stock 1 line. Not any time soon for me anyways...

That could because you got standard R1 with a different forks. I think it is 2 lines on R1M and 1 line on a garden variety (sorry )
That probably created confusion when people don't specify what bike they are talking about.

Cool that it works. Keep in mind though that this is for an Australian/European versions an it does not cover the extra bits the US or Canadian models have for the emission control.
I would love to get an ECU pinout for both, as someone from FTecu was explaining that the reason that people can't use European maps is that the ECU outputs are different between EU and US models. It is hard to believe that so I would like to check that theory.

wonder why they lowered the front on the r1m?? Maybe the bigger rear tire has some influence. Or the spring rates of the Ohlins. Interesting either way.

So...R1 shows 1 line when delivered, and R1M shows 2 lines when delivered.
Service manual shows 2 lines on both models.....strange.

Yeah, so much for manual. It is a dud In both cases it refers to position "A" showing the same picture. Remember that manuals are written by people who can translate the language not the tech info.
