: Anybody shimmed the rear on a 2006-2007 R6?

Hi,

Anybody did this on a 06-07 R6?

I'm asking cause i got this done to a racetrack in Hungary (5mm shim) and rear preload set at 2 (1 = full soft; 4= standard).
Without the shim the bike went very wide in corners and corner exits. After the shim everything went ok and bike handled very well.
Very stable on straight lines as well..

Back on the street, put the standard dunlop qualifiers (only 1600km used) and set suspension to standard.

I noticed on close tight turns that if lean the bike more, the front tyre has the tendency to slide and i found myself in a couple of cases to be near to a lowside. Tyre pressure is the standard for street 2.5 bar front/rear
I also noticed that if i take time to warm the tyres it's better and i don't get the front drop sensation anymore.

Temperature around is pretty warm 40 degrees C so low temp pavement cannot be the problem...

so, my question is the following:
Does the increased rear ride height can produce this drop feeling on the front (bike leans faster)? Does it stresses the front tyre more?

Or is it the Qualifiers?

PS: Till now i only had Michelin PP on my ducati 916 that were very stable at any lean angle, temperature and without much prewarm

I hear that's a problem with the R6 at a good lean angle; you lose a good deal of feedback from the bike.

If you raise the back of the bike, then you put more weight on the front tire (so my guess is that you are relying on it for more feed back). Also losing some stability (decreased rake) I feel gives the impression of the front sliding a bit. I suggest to start out soft and work your way to stiffer settings, and then pull it back a little.

So, I was saying to soften the forks a little, both preload (if not bottoming out) and compression and a little less rebound. If I lose feedback, I usually soften up the front (and the rear if I feel twitchy or not enough feedback) suspension a little at a time.

I hope this gives you some direction, and I hope that I am answering your question correctly!

Hi , i have a 2008 R6 and i have the same issue the from wants to tuck on slow turns , reading your article and seeing you have the same tyres dunlop qualifiers ( which are crap especially in the wet ). My bike had the standard suspension settings from the factory , so i would say it's definatly the tyres .
I will be changing them for Pirelli supercorsa pro ( as i am turning the bike into a race bike for '09' ) but a good all rounder tyre for dry and wet conditions would be Michelin pilot power 2ct ( always rated them give lots of grip and good feedback ).

I have never done this kind of stuff.
