Recommended DIY Suspension Settings
« on: November 02, 2018, 07:00:45 PM »
Hi,

I have a new 2018 SX that seems to handle like a pig. It's on original tyres that I hear are crap but wondered if adjusting the suspension myself might be an option to improve handling before I splash out on new tyres.

When I corner it feels like my bike is continually trying to sit itself back up so I have to fight it to keep it leant over. If I hit a slight ripple in the road or a bit of overbanding it feels like the bike is hinged in the middle.

I really want to fall in love with this bike but I'm struggling to at the moment due to this handling issue. I have owned over 30 bikes and don't think I've ever had one handle so badly....especially from new! My last bike was a Street Triple 765RS so its a tough act to follow in the handling dept but it should still feel better than it does. :003:

Any recommendations to try before I visit the tyre shop would be most welcome. I weigh approx 15 stone with all my biker gear on and ride solo 99% of the time.

Out of interest, has anyone tried over inflating the front tyre slightly to see if that improves the feel when cornering.

Thanks Goody

Goody, correct me if I'm wrong, but you've been here before  :027:

Suspension will help and tyres most definitely! Over inflating the front doesn't sound like a good idea to me, surely you want some squish  :027: not that you're gonna get it this time of year. Raising the rear end makes more sense, since the newer bike rides a little lower!

I have only just got mine 17 model 2 weeks ago and have come from a GSXR 600 K3. I am a total suspension noob and pretty inexperienced biker in general but after hearing a fair bit from various sources about this less neutral handling issue and after the ride home on mine of about 130 miles I decided that without really knowing what I'm doing I probably would make a bit of difference safely by just upping the preloads a bit. So the rear was at 10 clicks and I have put it up to 30 and on the front I went up by I think 4 turns. Defiantly feels better but I do realize I have used mad guesswork and I have only done preload. I also am about 15 stone (I think).

Had mine checked by a suspension specialist and set up accordingly. Needed to change the rear spring as factory one too soft.
Have a search on here, there are a number of posts re the suspension set up.

I would start by upping the preloaded in the rear.. Made a big difference for me. The standard settings are in the manual (or on a PDF on this site) so you ca. Experiment and go back to stock as you wish. It will never be 765 though! But you already know that.

The tyres aren't great especially when cold they

NB silly question I know but you have checked the tyre pressures since. You got the bike right?

Well, I decided to bite the bullet and change my tyres. Wow! What a difference, my bike feels so much better. Not just the handling but even riding in a straight line. I also noticed the vibes through the bars were nowhere near as bad as before. My fingers hardly went numb at all today when I was out for about 3 hours.  :001: I went for Avon Storm 3Ds as I already had a front off my old bike so just needed to buy a rear. I went with a 55 profile rear though.

Nice,. Not heard of the Avon storm.. Enjoy

That's interesting on the Avons. I had them on my Busa before the SX and they were great. Must have been the profile cos I found I could wear the strips virtually right off on the rear but never on the original Bridgestones. The S20's on my SX are hard for me to wear away the last 1/2 inch on the rear. I will be replacing with Avon Storm 3D's as a pair, whichever tyre wears first. They are soft on the outside and super hard middle.

Goody, still look at suspension set up. I started the bike off on PR4's as did not like what i was hearing about the oem tyres that came with the bike (had them swapped at point of purchase).  I had a look on here and someone with similar weight and height had posted the changes they made to their suspension so i took that as a start point and wow what a difference that made to the bikes handling.  made the bike feel even more better and panted than it was on stock shipped settings.

I wouldn't go over inflating the tyre as all that will do is give you a smaller contact patch with the ground with less grip.
