Trial & Error - Playing with my CBR600RRA suspension

You guys/girls are very right. I changed over my tires, l knew what to expect so l guess l forgot to state it more recently. Lately during my rides ive been very observant of what to bike is doing, instead of trying to get my series of thrills. Ive also shy away from "HEAVY" corning because l figure l can get into trouble fast testing a new setup in mid corner. I do however aim for the imperfections in the road and see how the bike handles. I then check the result against various suspension troubleshooting guides/ forum post/advice, and try an adjustment after a couple of days. I'll be years down the road before l get a true handle from this but the sudden surge of information is going a long way. Sort of like schooling except im exposed to TONS of misinformation and my own assumptions. So thanks guys. Hopefully someone else will get some direction from this instead of struggling in silence to avoid criticism.

Brain P - Ill have to measure and get back to you with those number but ill set the sag front to 32mm. Im leaving the rear alone for a bit to see the difference the front will make, im sure once l touch the rear the front wil need to be set again. I figured l would keep it in the middle of the recommended range. This bike is going to be street only. Eventually l will get a track bike, but its too expensive to start up down that path at this point. In the mean time ill have to continue reading before l can talk to you, im struggling to keep up.

Murf - I have no choice but to assume, Im assuming getting closer by improvements to handling. I.e. Is the bike absorbing the bump as oppose to launching over it. If l gain a "pro" by a setting am l also take a "con." Then go back to troubleshooting. Over steering is obvious, the washed feeling was having trouble reading whats happening to with my wheel. It would slide and l would bail and straighten up even on a modest lean.

mikecbr - I would agree completely. It's also come to my attention the stock suspension ( 2009 CBR600RRA ) has a limited range of adjust ability. Man-o-man the plot thickens.

You were sliding at moderate lean angles?

Well, not drifting type slide, but l couldnt hold a line. I could tell the front was sliding a bit causing me to oversteer. This was with the stock tires though and traveling through the off ramp on the DVP @ Don Mills South. Also the weather was a bit colder in the morning when l travel on it, so im sure the tire arent at their prime.

Just to give you a point of reference the type of turn. I wasnt able to complete get rid of the sensation till l changed the tires ( Metzelers M5 ). Although the new setting at the time negated it a bit. The firmer setting gave me better feedback to gauge my grip. I did set it a bit to harsh in retrospect.

You slide the front and oversteer? U sure?
 
the front wheel sliding is understeer and you were NOT experiencing this on the ramp you are speaking about unless you were significantly above the speed limit.
 
Sorry understeer it is, if criticism is critical ( My Bad ).

The front was a dunlop sportmax, the back is a Michelin 2CT. So the back holds well, and l almost fully broke them in, but the front has huge chicken strips ( +wax) and is worth ****. I had a huge issue with keeping my front under control as the back was usually planted. I just realize ive been confusing everyone.

I WAS UNDERSTEERING.

Hope this gets us back on track and on topic. Sorry for the confusion

1. Coming off the highway probably 100kph.
** Plenty of space to turn and screw up so l got a pretty decent lean coming off the highway, should no car be in the way.

2. slow from 80kph to 60kph as we come over the hill
** with slight breaking before l enter the turn. Usually there are car coming around as well from Overley. So usually lm bailing from anything crazy.

there is no wax on your tire, tire manufacturers stopped using slippery release compound many years ago.

There is nothing wrong with the tire, you understeered because you didn't lean the bike, nothing more.

The lean was fine, l just couldnt comfortably hold the line, so l straighten up and engine braked a bit. I would have needed more speed to keep going my typical lean. At this point my bike was "pogo-ing" a bit, the front would get a little light if l gave it extra speed; and that's just not cool.

Just a matter of having "balls" to commit to the turn with that much going on, not to mention that "washed" feeling. I cant tell if the bike was truly planted.

on the other hand l did managed to learn the difference between understeer and oversteer :cool:
 
I have never got my cbr600rr po-going on the street or track..... Actually of the dozen bikes Ive had the only bike that po-goes was an SV1000.

Usually a feeling that the bike doesn't want to hold its line is a geometry / tire profile / operator error situation. I highly doubt that either tire was actually sliding.

Some operator error. I progressed in the lean, so the line was less then ideal. Im coming from a v-twin, l got spoiled with cornering and the lower weight with that bike.

If sliding if giving you the wrong impression of what happened, ill reword it to...

"less then optimal grip"

C'mon guys l made a point that I WASNT DRIFTING. If am holding a line at lean it offsets ~20cm over a ~250 meters travel. Then ill consider it sliding as miniscule as it is. If my back is holding and my front isnt mid turn with a modest lean, and that's not sliding. then you guys maybe the first to diagnose it. You'll be famous. Maybe the "reciprocity" lean. Patent that before it too late.

Let now call it "offset" my turn.

Pogo - ing. YES, if you guys keep your stock settings then when braking/slowing down the weight will go to the front. It wont be absorbed properly. Then to rebounded to the back, which again wont be absorbed properly, then back to front, etc... Which l managed to fix on the front.

Why is everyone all about track, and nothing else. Proper street riding shouldnt be pushing limits. If l feel unsafe...

SURPRISE! Ill ease off.

Where the spirited riders, or did you call them all out to the track. I enjoy the ride nowadays not petty thrill seeking on streets.
 
Great.. now my penis hurts. This thread gave me herpes.

If i shove it in the toaster will that fix my herpes?!

Spirited rides don't get posted on public forums.
 
If i can do this on single compound sport touring tires with suspension settings not set for the street.. why can't your Dunlops do it?

speaking of which, when is the next track day with a suspension specialist? (aside from calabogie)

Because l dont feel like it, not because l cant. Too many idiots on the road and problems on toronto streets to bother. Once in a while but not regularly and certainly not every turn l come across.

When l say spirited l mean with gusto not dragging pegs/knees. I did it all the time with my sv650 at from stopped red light turning left. CBR600 l dont have that same confidence going low speeds. An on/off ramp is a different story.

Please dont assume. This is already a pissing contest.. Great! Another thread lost to GTA machos

I thought you said it was a suspension issue, not a "i don't feel like it issue". If the only thing holding you back is your desire, what does your suspension have to do with anything?
