    Hi all,

    I have a brand new Street triple S, and sometimes (today for example) I encounter a probles with downshifting from form example from the 5th gear to the 1st gear. I pull the clutch lever all the way in, step down on the shift lever and the bike doesn't down-shift. I need to slip the clutch lever a bit and pull it all away again to down shift a gear. Not handy when you approach a traffic light.


    Anyone experienced the same issue as me?

    Kind regards,
    Jurgen

    I'm having clutch issues with my 2018 765R but have not encountered this issue.

    Regarding your issue, where is the problem? There are 4 downshifts from 5th to 1st. Can you provide more detail? What gear is it getting stuck in, and at what RPM does this happen?

    Today I approached the traffic light with ~55 km/h and tried to downshift from 4 to 1. The downshift from 4 to 3 didn't work so I had to slip the clutch a bit to make it happen. Same for 3 to 2 gear but from 2 to 1 gear it worked as it should work. Next time I will provide more precisely the details.

    Hi Jurgen, did you check that the gear selection arm is tight on the spline, I've found mine loose the other day on the Speed, was also experiencing some difficulties with false neutrals and gear grinding on two occasions, upon investigation saw the bolt was loose. Worth a look imo. If not that simple straight back to the dealer mate. Hope you get it sorted.

    What Angus said ^. If the gearshift linkage arm is not loose, then bring it to the dealership as they might need to reposition the arm so the shift rod is able to push it enough to effectively move down the gears.

    Are you trying to shift from 5th or 4th down to 1st in one go, I mean pull the clutch once and hit the shift lever 4 times? If so I think that may be the issue. Bike gearboxes don’t really like doing that, they need shifting one at a time to go in smoothly, preferably with a blip of the throttle to match the revs for the next lower gear.
    Making sure the lever is adjusted to suit you and is tight on the shaft as well as proper adjustment of the clutch lever will help, as will having the correct drive chain tension. Too much chain tension puts a lot of strain on the gearbox sprocket which hinders smooth gear shifting.

    Agree if it turns out to be a technical issue but re reading his last post he is in 4th gear at 55kph(34mph?) so it may be technique rather than technical.

    Possibly clutch adjustment or loose lever? I wouldnt touch it, not on a new bike.If it is technique the dealer may give him a few tips.:) Thats your depreciation money right there.

    Hi Angus, I checked the gear election arm and it is tight to the spline. I'm going back to the dealer.

    Hi Yorkshireman, I'm 47, obtained my driver licence 2 month's ago so every time I drive my bike I learn. So if you have some tips, please feel free to share them with me.

    Kind regards.

    Ah, congrats on getting your licence and I welcome your philosophy of learning every time you ride the bike, something more of us ought to subscribe to.
    The best way of shifting gears is to take them one at a time like I said above. So for example if you are in 4th gear and you are coming to a halt at a junction where you know you will be stopping and need 1st gear again to set off then at a reasonable distance away pull the clutch, tap the gear down and at the same time blip the throttle slightly to match the revs to the lower gear. Repeat for the change to second gear and you should be ok to stop in that gear. Obviously while you are stopped drop it into 1st which should go smoothly without blipping the throttle. It’s all a matter of practice and the whole operation of clutch, gear, throttle blip should be done as close together as possible. The whole idea is to not let the engine revs drop away because if you do then the gear will engage with a bang and if you then release the clutch without matching the engine revs to the required level for the lower gear you risk the rear wheel losing grip and increasing the potential for an accident.

    Hopefully this little vid can help, I hope I haven’t made it too complicated, ride safe my friend.

    I don't blip the throttle when downshifting. Do we really need to? The 765 handles it just fine.

    Just my two cents...

    Blipping is a great advance technique. I always find myself doing it. It’s more tricky with the 765 as I have to get a feel of the slipper so my left hand is in sync with it.

    Having said this, less blipping is necessary if you wait for the rpm to come down before downshifting. This is the case when you’re just coming to a stop vs trying to setup your speed for the next corner. I learned the hard way during a track day that downshifting while the rpm is too high can result in a rear wheel lockup even when I was blipping.

    Please take care when learning to blip. Fully close the throttle before re-engaging the clutch in-between downshifts.

    I hope this helps.

    Not necessarily an advanced technique I think but essential if you are going to get a smooth downshift (unless you have an autoblipper as part of a quick shifter).
    With practice you can “sustain” the revs and downshift twice or even three times just hold the revs where they were and tap the gears down. *Dont try this yet jte71, get the basics first ;)

    I've had exactly the same problem with my RS Street - bought new a month ago.
