    Slow speed handling

    Hi , After noticing poor handling at slow speeds i checked tyre pressures and they were out quite a bit ,so i read the 'correct pressures' and put in 36 front and 42 rear ,took it out for a test and while fast speeds are okay ,slow speed i.e pulling away at a junction or going round a corner slowly or even slow riding in built up areas ,the front feels frighteningly uneasy to the point of was glad to make it home,almost felt like riding on ice or with a flat tyre. I would be greatful for any help please .

    Tyres are Pirelli angel st look fairly new lots of tread still on them . Also just had new stearing head bearings fitted dont know if any of these could be the problem.

    If your head bearings are overtightened they can cause your bike to feel strange at low speeds, it will feel like it is rolling side to side on it's tyres. They should be tightened just enough to stop them knocking

    I have the Pirelli ST's on my 2012 and always have them at recommended pressures. I find they work well for me although, because I don't ride enough I too find low speed an issue  :oh_no:

    The other thing to think about: the ST was discontinued some time ago. Check the age of the tyre as they all deteriorate over time regardless of usage, if they're over 5 years old you may want to consider a change, (20+ years in the tyre industry :005:)

    Similar subject on the go on another thread, so repeated my comment here.

    Just to add into the mix.

    A couple of things that make a big difference to the behaviour of the tip in at slow and faster speeds.

    Tyre choice; I was running Bridgestone S21's and loved them, especially in drier weather. Cons where- squared off in no time, tended to track any lines or creases in the road surface and not very confident inspiring in the wettest conditions (trouser change time).. Now using Metzelers with a profile that gives a vastly improved tip in, loads more confidence and traction in the wet, and up till now looking much better mile for mile on the squaring off front.

    Suspension; A combination of changing the front fork oil and a Hyperpro rear shock has brought high speed stability and cornering to a far better place on the bike. Gathering confidence and that unique bond with the bike we ride is vastly reliant on a compliant suspension that is set up for you. These bikes need the fork oil changing regular, so many bikes out there are running old, thinning oil that gives a vagueness at high speed cornering, and odd tip in characteristics at slower cornering, not to mention dive when braking.

    Have you still got this problem?   Was it just turning in too quickly?

    Took bike into shop that put head bearings in they say they had over tightened them and it is now okay ,but cant get it back due to work etc till next Saturday so wont know till then, but yes it was turning in badly at slower speeds eg slowing down for corner or roundabout even in a straight line when going below 30 mph.

    Picked bike up from shop today ,they admitted they had overtightened the bearings and sorted it out,seems much better now.
