    Gearbox problems

    I have just read that 2014 Roadsters suffer from the dreaded circlip problems in the gearbox. I thought these problems were sorted out by the 2010 model years. I purchased a 2014 model on that understanding 5 years ago and have no trouble at the moment. Can anybody say if this is true?

    Gearbox Issues

    Well, I am regretting buying my R3 2016, it only had 8500kms so I thought it couldnt have any issues but how wrong I was. In every gear under load I can feel something like a jutter. I dropped the sump and checked the filters nothing, dropped the oil in the diff and nothing. Spent a thousand...

    Gearbox parts

    I’ve got to the gearbox and found the damaged gears. This is a low mileage 2014 roadster. Has anyone ordered the parts before ? Where’s the best place and do Triumph do a kit or stronger gears. It may even be the forks didn’t fully engage the gear due to bending possibly ,not into the depths of...

    Gearbox - exit stage left - need Robinson info

    A couple of months ago on a left turn about 300klms from home I heard a big bang that stood the bike up - crapped myself. Turns out the cut lip had come a drift. I have it all apart and have the Robinson billet gear and have it all at the shop being back cut. I really would like to upgrade the...

    When splitting engine cases for access to gearbox if there is a gasket between the jointing surfaces or is it only a sealant that is used?

    Gearbox issue

    On the ride last weekend I encountered my first ever mechanical issue whilst on a ride. The gear lever feels different and it's harder than usual to select gears and it now jumps out of gears when there is no load on the motor. Does anyone have any ideas what it is and how to fix it? 2008 R3C...

    Jumping second to Neutral at max rpm

    Hi guys R3r 2012 owned since 2017, with TORS and a remap. I've trolled all over for various clues, but most concerns are false neutrals or dropping out of random gears. My issue is when I crank her open at 6.5k rpm in second it jumps into Neutral. No other gear, no false neutrals, and it only...

    Gearbox lubrication

    Whats the story for the roadster. I can't find anything on fluid replacement for the gearbox. Is the gearbox lubricated with the engine oil? I can't find anything in the manual either. Probably a bumb question. Thanks

    Annoyed with Triumph right now.

    So long story short, I bought my 2015 R3T about 4 months ago and am having transmission issues. It has ~5700 miles on it and I got it new, old stock. From day one it has always been a bit finicky about finding 1st gear from Neutral (almost exclusively on a cold start). About 1 out of every 10...
