    Unusual tyre wear

    This wear seems unusual to me any idea's the tyre's i am used to pre 1989 wore on the front right but to a different degree to this wear pattern, still the tyre new has a different shape to tyre's i remember to start with the radius on new tyre's at least in the pilot 4 types seems steeper on the sides to me.

    its the battery...

    but seriously i would say your forks are twisted and or uneven or your wheel is on the piss. either that or your forks are so soft its been rubbing up around the oil filter / radiator

    You need to control your rebound dampening... Currently forks are returning too fast... so you need to slow down the rate of return.

    That and there is seriously something wrong with your front fork set-up. Can't believe you've left it so long and let it get to that point.

    Thank you tim for the advice and you to hilllz.

    Bikes have changed from what i know, but it has always felt soft in the front to me the preload is the only adjustment it has apart from going with a heavier weight oil.

    Total motorcycles vic park are fitting a new tyre another Michelin softer in compound, evan checked the rear and said it is misaligned which he said would contribute to it and to be honest i have not maintained this bike enough, i was pretty shocked when i noticed the front the rear i can control but lose the front your gone.

    I have been advised tyre pressures are critical nowadays and that contributes to the wear.
    So you were right i will be checking them with a gauge from now on not feel.
    In my defence tubeless radials had only just come in when i gave up riding.

    What should type pressures be around on road bikes ?

    That looks a lot like one of the front Pilot Powers off my Bird before I stiffened the springs up
    Only difference was mine had canvas showing

    Depends on the bike and temps of the road, I run my Daytona on 36psi in the summer months, when it cools off I back it off to 32.

    apparently the expert at Avon tyres was quoted saying 40 psi as an all round figure.

    If pushing the bike hard a pressure that high removes a lot of carcass flex and your tyres don't heat up, with that comes cold tearing of the rubber and if you're slipping and sliding faster wear, the hotter it gets the better it sticks within reason.

    Lower pressures allow more flex and with it more heat, hotter softer rubber generally wears more quickly.

    One of my bikes requires 36 in the front and 42 in the rear, another is 29 and 32, another is 34 and 38...

    If you can't find a manual or recommendations for your bike model then 40 in both won't cause anything immediately catastrophic for everyday riding but neither will 30
    Do you remember the good old days before the internet?

    when arguments were only entered into by the physically or intellectually able.

    I though most sport bikes recommend 36 front 42 rear. It's typically what I run mine at. Track would be different but that's good for the street.

    Reading this ...I feel a bunch of you really really need to book a date with Marty Moose... for suspension 101.

    srsly if you don't know what you should put in your tyres....you gotta find out BEFORE you go out for another ride....do it do it now.....google it if you are a lazy cunt.

    Evan said this tyre looks underinflated and the wear was different to mine.

    Evan at total motorcycles went right over the bike for me i told him how a couple of guy's at jarrahdale told me the rear was out slightly when they had a look at it, i had been telling them how in the rain with a strong crosswind the rear stepped out once, and the bike rode at an angle into a crosswind.

    Anyway the tyre pressure was ok an evan feels the wear was caused to some extent by the rear axle being out around 5 mm, and the forks needed to be adjusted, i fitted a softer compound michellin power rs which steers a lot quicker than the pilot 4 tyre and the bike feels great to ride now, turn ins are so much easier and the tyre heats up quick and feels to have a lot of grip.

    I am going to have to start maintaining the bike better.
