    Hi everyone I am new to the site. I have just bought a 2011 speed triple with only 4800 miles one owner bike (and yes mileage is right lol). I have been riding 37 years and strip cbr 929s for a living so know my way around a bike. and have 3 other bikes. What i would like to know is has anyone had problems with warped Front brake discs. (i am 99.9% its the problem) when i take the bike out once brake discs have wormed up i am getting a juddering though the lever and under hard braking can feel it though the bars as well. i have had calipers off cleand everything discs as well. checked head stock just in case. I have seen on some sites people saying the 2011 bike had a bad batch of discs as lots have had them changed under warranty is this the case. I think i am just going to buy some Brembo discs and pads. Oh bike is under warranty as only ridden it twice. any info would be good. thanks.

    They could be warped or it could be the bobbins that allow the disc to float that have seized up. Did you clean these when you cleaned things up? I use a large flat blade screwdriver to turn them whilst giving the area a good spray with brake cleaner. Check for “run out” by raising the front wheel and spinning it whilst observing the disc in relation to the fork leg, ideally a dial gauge tester is best.
    Welcome, enjoy the bike and the forum.

    What you describe sounds like warped discs, if it's still under warranty then get it back to where you bought it from.

    FYI - Warped discs can be caused by sitting with the front brake on following the discs getting very hot, for example after really heavy braking on track the coming into pit lane & holding bike on the front brake, as the rest of the disc cools, the bit clamped in the pads doesn't, this can cause them to warp.

    Have you cleaned your bobbins and if you have dont powerwash them I thought I had warping and it turned out to be clogged up bobbins. then I washed them with a power washer and this caused them to stick and give the same effect.
    Put a small bolt through the bobbin with a washer on ether side, bolt, tight enough to turn the bobbin ( not tight at all ) and watch the sh1t fall out, when you turn it.

    Thanks for reply lads. shop is picking the bike back up Friday to check it over. to be honest the shop is taking the piss for a Triumph main dealer. They said they could not do anything for a month as they are all booked up. I bought the bike 3 weeks ago and only had the bike out twice as they had to pick it up and replace the clutch after 3 miles. got bike back to find brake problem on next ride out. They tell me they will try and fit the bike in over this month ? REALLY. If they do not have it fixed by the 25th i am going to pick it up will sort it myself and then take action to get the money back for what it cost to fix as they will have not fixed it in a reasonable time frame. I think its a piss take a Triumph main dealer sells a bike that was not fit for the road at time of sale as they never test rode the bike before the sale. I will hold back from naming the shop to give them a chance to sort it out. but if they do not i will list the shit they did not do, that they said they would do when i bought the bike.I have Never come across a shop that could not give a shit about fixing a problem on a bike they sold asap telling a customer we can not look at it for a month is a bloody joke So far i have owned the bike 3 weeks and still can not ride it. They think they are being smart by getting the bike off me and think they can still leave it sitting in the shop till next month. Big big mistake will not be the first company i have had a fight with. Its not much to ask when you buy a bike from a main Triumph dealer to be able to ride it ? watch this space to see how A Triumph main dealer treats its customers once they have your money. I knew I Should have bought the CB1000r instead

    the bike has not really been used in the last 3 years 28 miles so it needs a good run. had the clutch replaced last week due to not changing gear right.now all good

    Picked up my speed triple the other day. it was pretty much standard. iI have added Beowolf exhaust and grills, short levers, it has a belly pan and Triumph LED indicators, up graded screen R&G crash mushrooms and bobbins all round. i think that's it. and is like brand new so happy with the way the bike looks just want to get it ridding right lol. It needs a good ride out to shake off the dust.

    Hi Englishbandit,

    Had the same issue with my TTSE, developed the shudder on my way to the ferry at Newcastle going over the Coldstream road. I checked all the forums for feedback and checked all the other potential causes and eventually had the runout on the disks checked and one was on the limit, I bit the bullet and bought new disks & pads and installed and now back to normal. I should say that I cleaned the bobbins as the disks are semi floating but did nothing to cure the shudder.
