  • Cornering - please diagnose

    Upgraded to my cbr 600rr 6 months ago. First proper bike and loving it. I am starting to push the boundaries a little and I am wondering whether this is normal:

    When taking nice long smooth corners (not necessarily at crazy high speed), with body hanging off somewhat, I reach a point where the bike gives me heaps of resistance. ie. it does not want to lean any further. I feel the only way to fight it is to countersteer a little more but I don't want to experiement with that too much especially on the road.

    I am not talking about what I would expect to be 'normal' resistance from forces at play etc. This is a very clear boundary that appears abruptly. I have not riden other big bikes so nothing to compare with (though never felt that on my baby ninja that I used to thrash around quite a bit).

    My rear tire is slightly quare now but nothing that would be expected to cause any dramas. Bridgies BT 016 I think on the rear and the front is a new BT 003.

    Body position from photos on trackdayz seems to be OK (I felt this at trackdays as well BTW).

    Suspension set up by our own Mr Moose.

    I feel like the bike could go significantly faster around these corners but this 'boundary' is pissing me off. Can someone please diagnose the mofo for me.

    Thanks a bunch

    Did your model come with the electronic steering dampener?

          Also are you sure your not being to gentle with it! i found my 600 to need quite a bit more muscle to crank over than the little 250! maybe lend it to a quick rider and see if they have the same problem then you will know if its you or the bike!

            could be a miss-match of tyres? Or maybe time to get MM to have another adjust to suit your new skill level?
            yes, i am ignorant
            yes, i am a prick
            no, i don't care
            you make me sick

              Think next time I'll rent one of the 600rr's at Champions to compare.
              My bike is the 06. Pretty sure there is no electronic damper (or any other kind for that matter).

                Put up some photo's from your track day as they will certainly help. A miss match of tyres is a possibility. Other than that buy one of the spots for tomorrow and come and see me or one of the other coaches to help you in person.

                    Go faster and it'll naturally continue to lean over. Either enter faster and tip in or enter slower and gradually give it a tiny bit of throttle to force the bike to lean it self over (No, you're not going to loose traction if you're on the gas, unless you decided to close throttle, then smash it open while on a decent angle.)

                      What sS said, could be in need of some small adjustments, if you find yourself double apexing corners etc i would think further adjustment is required, but Marty has always got my bike spot on. Maybe check your tyre pressures too! Just a thought.

                        I recently had a similar problem - when cornering i too would encounter resistance that i felt was not consistent with the bike i have - anyway long story short - removed the after market "Eagle" tinted screen and refitted the - smaller - original yamaha screen - shit - what a difference - instantly noticeable better tracking control and way lighter and more manourverable in the front end - wind flow and the resulting effects - were now fixed.

                          I can tell you now that it is definitely due to a mismatch in tires , you are running a slightly squared BT016 road tire with a race tire on the front which means even though they both may have the same numbers on the side of the tire this doesn't mean they have the same triangulation , race tires always have a steeper profile as you will need to get the bike turned quicker on the track and from my experience the bridgestone 003 has a fairly steep profile and turns in relatively quickly. Here is an idea don't skimp on your tires and put a rear on that is the same as the front because they are the first thing you need to have right before you will improve your riding.

                            Ok, I'm a Noob rider, so I'm not going to tell you how to ride, but I am curious why you're hesitant to simply countersteer harder to achieve the desired lean. I find that if I don't have the lean angle I need, a little more pressure forward on the inside bar and the bike tips right where I want it. Isn't that what you're supposed to do?

                            Just interested, you're the one on the bike and I'm hardly a qualified instructor.
