Ok have been through the search page and not really any luck to what I am looking for? At what RPM are we supposed to run to keep the battery charging? Just got back in from a real nice run today(now at 187 miles), do like I always do and plug in the battery tender and it took a few minutes to come up to the 80% mark. I am still in break-in mode so haven't been much over the 5,000 mark yet. I have been maintaining(and varying) speed about 62@ 4,000 rpm. Now in town have been around idle to 2,500 rpm. Any GOOD advise?

The higher the RPM, the more it will charge. The 08's have the lower output stator, so you would need to spin the engine faster to match the output of the 09's, but it still isn't anything major. Just ride it and forget about it.

The only time you *might* have an issue is with a ton of high load accessories (heated suit) and short trips.

so it should get better the closer I get to the 600 mile mark. Are there still a few on here that haven't broke the DON'T GO OVER THE 6,000 RPM UNTIL THE 600 MILES ARE UP. I know that is opening the can, but just asking. I don't want to ruin this piece of art that I just got. Thanks again Froggy.

That won't "ruin" it. Better to exercise it than be too conservative.

Sorry but I'm guilty of paying lip service to the recommended break in routine.

I have 305 miles on mine now, I tend to move between 70 and 97 on the freeway (97 is about 6K), change gear up about 5000 and use WOT quite a bit to get me to cruising speed.

I rarely let the motor lug (to me anything under 2500 is making the engine work too hard at large throttle openings).

Opinion varies over the correct approach, I'm just doing the same with this bike as I have done with several other new ones..

I did have one "naughty" afternoon that saw 170 on the clocks for a brief period..

Here's hoping they don't get to see the data at the dealership when she goes in for the 600 mile service..

6,000 rpm max until 600 miles, lol! I wasn't able to do that on the ride home.

You have some kind of self control. I eclipsed 6k rpms before i even new what happened.

It's 600 for the first 300 miles, then 7500 until the first oil change. With a 7500 cap, you can really have fun on a great mountain twisties ride, honestly -- it's not much of a burden to break one in by the book -- should only take you a weekend.

In general, this bike DOES like a little higher RPMs. It's a source of much debate here, but my own personal finding is cruising above 5k is generally a good thing to do and will minimize any number of "problems and issues" many here have had.

Once you are past that first oil change, my experience with this motor is it does like to be run, and run hard.

I have 3 of them, and in excess of 50,000 miles in the seat of an 1125r, with over 10k of those on the track.

Don't treat it with kid gloves. *RIDE* it hard from time to time.

I know the exact figures are posted here somewhere if you search, but I am pretty sure the peak charging output occurs somewhere at or above 3,500 RPM. Choose your gear accordingly, and all should be well.

454 miles now. I put about 90 miles on the bike with greater preload. I am working my way up the ladder on the preload. it's starting to feel like the smooth version of my built up s1 suspension. Another quarter turn in on preload and testing will resume. My primary concern is dive on braking and trail braking. goal is no loss of road feel in suspension during braking.

I really started enjoying the bike today. Rather than obsess about RPM shift points I just rode it and listened to what it liked and wanted to do. I wasn't exceeding the break in rpm limits just shifting a lot.

It seems that you can short shift a lot and get some pretty good speed, then when you back off for just a bit it seems you are two gears away from any type of power. Not at all like the sporty based 96 s1, but I like they way it squirts ahead so effortlessly.

I'm getting there. after suspension setup complete, Denoid/just the plug.

im keeping to the book with my 2010, but have kept revs above 3000 even when new, as the engine feels happier like that. near 1000 miles now and have took it to about 8-8500 rpm, but like to work my way up to the redline over time, rather than give it max revs and throttle immediately after first service.



the engine is loosening up nicely. i find it needs more revs, and higher gears than my xb, but thats the nature of the engine tune, it seems happier to run above 3000 to get decent performance, while the xb doesnt mind lower revs and needs less gear changing.

i work in engineering, so have a bit of what might be called "mechanical sympathy" for all those bits whizzing around and up and down.

my 07 Scg is near 18000 on the clock, and feels the same as it did 10000 miles ago, so im doing things the way i like.

charging shouldnt be a problem if you keep the revs up at a decent level, but if your dealer is a good one, then ask them to check it.

sorry about starting a thread about break-in. Was looking at rpm's and hoping that I can reach the 6,000 rpm to help ease the charging system.

Shouldn't be a problem if everything's working right.
Loretta has a hair over 24k miles and still has the OEM battery.
She gets put on the tender intermittently.

I "putt" at fairly low rpm when commuting, 2.5krpm to 3.5 and have had no battery issues.
