Hi guys, I’ve just joined the group, and I’m after some suspension advice. The bike will only really be used for track days, and I’m after some suspension advice. The bike is plenty fast enough but it’s bloody hard work on track, who is the best person to speak to about getting the suspension properly set up for my weight (101kgs plus kit) I’ve tried playing around with the suspension myself but I don’t know enough if I’m being honest. Cheers in advance guys
 
hi Neilj777, is it possible for you to take to track side suspension specialist? Because you can learn a lot from the person if your background is trying to gain some fundamental knowledge of suspension.

they know the track you going to ride on, and sure can help to set up fundamental of sags to start you off and adjust accordingly

im about to buy a spanner c wrench for the shock so I can set sag properly for rear. And someone on the forum pointed out by unplug the electronic socket from front fork so we can access the preload adjustment by utilizing the front fork Socket.

hope these info should get you start to work on it, I’m sure this can raised lots of preferences for you in the future.

fyi, I like my suspension plush, rebound really slow, semi high medium on compression.
 
i agree. i was like 95kg (210 lb) and the bike was moving all over the place at corner exit without a spring change. I am not that tall (173cm) so i knew i had to adjust. i'm now at <84 kg's (<185lb) and the bike feels total different. If you are tall like i'm sure you are, i would look into a different spring

Cheers JIM, I’m sure your right ad it’s mainly on corner exit I’m having problems. The front feels really planted to be fair. I’ll look into getting the spring swapped over. Cheers for the help guys
 
I thought I was going to have to swap springs out too, but I join Dave Moss’ tuning site. I watched several of his videos setting up other peoples V4S and was able to set the bike up perfectly for me. It totally transformed the bike and my confidence in it.

Did you ended with fixed setting or still using dynamic?

Suspension setup really is a dark art. I used to be the driver/tyre man/spanners on a British Superbike team an saw people working into the early hours searching for a setup, which they didnt find until near to the end of the season. A new team boss came along and said this "Go and set up your bikes and ride them today, apart from wet settings you arent changing the dry settings after today" and that was it. He made me think, why do people try so hard with suspension? Later in a team meeting he (the boss) said that his rider had won the BSB championship without changing any settings in the dry and became a WSB champion later. So, who are we to not just leave our settings alone and ride around any feelings/problems?
 
That’s what I do. I set the suspension up and then leave it. But you have to do the setup. You seem to be suggesting that us mere mortals should just accept the bike from the manufacturer and not change anything. That’s silly...

Some riders can ride around problems, look at Casey Stoner when he was at Ducati. Maybe, in the example you give above, he had a rider who was imperious to setup change!

Each to there own, on my S1000RR race bike, a 4mm ride height difference can often make a 1 second lap time difference, for me.
On my V4R, I adjusted the swingarm pivot from -3mm to +3mm, on advice from a race team. Whilst the bike handled OK, it was really hard work (I couldn't finish a 20min session), and also 4 seconds a lap slower.

And sometimes, the changes make no difference to lap time, but just 'feel' better.

Ultimately though, do whatever makes you happy.
