Suspension Setup
09/30/13 8:04 AM

Hi, just had a so called suspension expert check out my bike and he reckon's my rear shock is too hard. He backed off the pre-load a few turns. Now both front and rear static and rider sag are pretty close to each other. He also softened my rebound settings a tad. Has anyone else here had the same opinion from an expert? I'm 82 kg.

I was experiencing the rear wheel sort of bounce/willow in high speed cornering. Waiting on weather to give it a good test, will report back.

Hmmm...well...I know what you mean by 'wallow'...I found adding some rear preload(two turns),some compression(half a turn),and some rebound(half a turn) solved that deal...for the rear.I recently went with 3 lines showing on the front preload..8 on the comp....6 on the rebound damping.This works very well for me at higher speeds and moderate speeds.175lbs.At triple digits...she smoothes right out all the way to 190.Very stable at 190.

Wallowing I think is the front suspension.

My rear used to hop off of bumps more than the front. The rear was flying up off the ground. Yes the rear shock was too tight for 200 lb rider. Just right when you add a 100 lb passenger.

I adjusted my rear by turning the rebound damping to 2 turns out. (stock is 1.5 turns out)

Compression damping is 2.25 turn out which is stock setting and where mine was left.

Turn the adjuster screw all the way in clockwise first AND MAKE SURE YOU COUNT THE # OF TURNS before the adjuster screw stops all the way tightened in. Write the last setting down so you don't forget. That way, you can always set it back to wherever it was if your adjustment turns out to make things worse.

The rear shock preload was adjusted by turning the spring tension nut 4 complete turns counterclockwise. Each complete turn of the nut will amount to about 3.5mm increase in sag.

Now both front and rear static and rider sag are pretty close to each other.

I'm not sure what you mean by "very close."

Here are my measurements last time checked 4 years ago:
FRONT
static 11 1/2" - loaded with me and gear 9 29/32" = 40.48mm front sag

REAR
static 18 5/32" - loaded with me and gear 17" = 29.46mm rear sag

before I adjusted the rear as described above, the rear sag was at only 15.88mm. I almost doubled the sag height by adjusting the rear to where I have it now.

Some day I would like to get some Ohlines on there. HaH!, the track suspension guys didn't even know what to say about my stock rear suspension.

Hi Guys, thanks for all your feedback and inputs. Maybe I should try to explain a bit better. While entering long highspeed bends with a high lean angle, I don't get a lot of confidence from the rear tyre as it feels like it doesn't track the corner with me as if it tries to bounce up from the corner even though I haven't exited the corner yet. The road is nice and smooth with little bumps and I run Pirelli Rosso 2. Just feels like the rear isn't gripping as much as it should. I have soften my rebound so it doesn't return to it's full stroke too quick but still no joy.
