    Hi All,
    Can anyone help me with my 2012 speed triple with 9,000 miles on the clock that has now decided it doesn't want to stay in gear when deaccelerating.
    I went out for a nice ride yesterday and on the way out the bike performed faultlessly as always but on the way home she kept going in to neutral when slowing down, which definitely made my life flash before my eyes a few times!
    This happened almost every time I slowed and it didn't matter what gear I was in.
    The bike is slightly over due a service which is booked in next month.
    Thanks in advance

    Does the gear lever fit directly on to the shaft or does it work through a linkage? If so it may have worked loose and therefore out of adjustment or the joints may just need greasing (being a lazy old sod I tend to squirt mine with a chain lube aerosol can thingy, which will probably upset the purists, but it seems to work ok. Look, it's grease innit??).
    Thereafter things may get expensive!:eek:
    So try tightening/greasing as seems appropriate before delving deeper. Fingers crossed!:)

    Cheers Steve, I'll try this first thing in the morning.
    The most annoying thing is I've got the week off and was planning on riding my way through most of it :(
    Hopefully it's just an adjustment thing.

    Have you checked your chain tension, if not might be a good place to start?

    I've noticed this morning it's very hard to get into gear almost crunchy! The gear linkage seems ok, the chain is a tad slack, but stationary the gear box is extremely crunchy and difficult to put into gear?
    Feels like it's knackered :(

    No, half ton are you thinking it might be the clutch? The clutch feels fine. It did hold in gear when accelerating, it only dropped out of gear and into neutral when coming off the gas.
    A motorbike mechanic I bumped in to today said it might be the 'selector fork' but he didn't know anything about speed triples.
    I've got a feeling its broken lol just need to know if it's something I can fix myself, otherwise it's gonna cost me a small fortune to get someone to investigate and repair.

    There was some issue's with the selector fork on some early Street Triple's might be worth getting someone to have a look.

    To be honest how you are describing it I don't think a service will cure it.
    You probably need to take it to a triumph expert but a main dealer will be expensive.
    I suggest you contact Clive Wood. Clive used to run Jack Lilley's race team but now operates out of Swineshead near Boston Lincs. Tell 07752477738

    If I was you a Triumph dealer booking to road test and report findings, you could do a check of engine oil and oil sump plug for metal contamination.

    I had the symptoms you are describing with my Sprint GT. Bike would jump out of gear when in a lower gear going down a hill which was scary and also would randomly pop out of gear when accelerating.

    It turned out to be a bearing on the 'gearchange detent arm' had become detached (whatever the heck that is). Was replaced under warranty along with a new clutch. Not too clear why they replaced the clutch but I know that they had ordered that up as that was there original suspicion.

    Hi guys, sorry for the delayed update, house move, another baby on the way and work seem to have left me with no time to even wipe my own arse!

    So I managed to get out on the speed today, I've adjusted the chain, gear lever, clutch and changed the oil and filter. And for 20 minutes it felt like a new bike until it slipped out of gear while in 2nd slowing down for a roundabout.(another slightly scary moment), but it didn't do it again, so now I'm really confused.
    Think I'm just going to give up and let Triumph have a look.

    Resurrecting an old thread here - did you sort this problem? My S3 955 has just started doing it now and again, so far just when using engine braking in second just coming up to a junction. Wouldn't want it to happen halfway round a corner cranked over.

    Update: It turned out to be a detent arm and bearing? (I think that's what he called it!)
    The bearing was swimming around in the gearbox but luckily it didn't damage anything else within the gearbox.
    1 new detent arm
    1 bearing
    oil & filter
    Gaskets
    labour
    = approx £280
    Which I was very happy with considering Triumph quoted me £250 just to diagnose the problem!!

    Thanks for the update JayJay. My bike is currently down at the dealer for another issue, so I'll call them this morning and see if they can check this out too.
