    My 6 month old T120 with only 1500 miles on the clock is back at the dealership with gearbox problems. Went out for a run on Friday and found difficulty changing down. It would change if you gave it a double tap or if you were at crawling pace. Called the dealers and decided to go straight there.
    The situation got worse as time went by and I had to stop on hills half a dozen times as the bike was stuck in fifth. Going up the box was no problem but going down became almost impossible. Waiting to see what the verdict is from the dealers but it's certainly taken the shine off my beautiful Bonneville.

    Spoke to the dealers today, Cobb & Jagger, Shipley and they've stripped the box down and have identified an excessively worn detent wheel. Not clear how this could happen on a nearly new bike. They think It's a manufacturing fault which doesn't fill me with confidence as these things are made in batches and I don't want a repeat failure sometime when the bike's out of warranty. To make things worse the part is on back order so it looks as if It'll be off the road for an indeterminate time. All you T120 owners out there should keep an eye out for the same fault developing. Fortunately my trusty CBF1000 is still going strong.

    Sorry to hear about this, it certainly does take the joy out of a new bike.
    You are quite right to be suspicious about batch manufacture, the root cause of this could be the raw material or the heat treatment process.
    Might be worth looking at getting a full refund within the warranty period or certainly extending the warranty period F.O.C. to cover the gearbox.

    A very disturbing story. Hopeful it is a one off and you get your bike back quickly.

    I'm no legal expert but I understand that you can only insist on a refund if the fault appears within thirty days of purchase or within six months of purchase if the first attempt at repair is unsatisfactory. After that it becomes very difficult and I discovered my fault shortly after six months of ownership. I think getting an extended warranty on the gearbox is an excellent idea and I'll pursue that angle when I collect the bike after eventual repair. My main concern now is how long it will take Triumph to complete this back order as, with winter coming along, I won't get a lot of opportunity to check out the repair by doing another 1,500 miles in the next few months.

    The dealers delivered my T120 back yesterday. The official cause of problem was a deformed selector shaft. Triumph Warranty dept immediately diagnosed the fault from a description of the symptoms supplied by the dealer so one wonders if they've met the problem a number of times before.

    Hi Guv,

    Sorry to hear this mate. It's a real eye opener regarding Triumphs continually falling build quality. Especially the shock snapping! :eek:
    I hope Triumph sort it out asap & to your complete satisfaction.

    After four weeks Triumph has supplied a modify gear selector and will replace the snapped rear shock under warranty. But I have replaced both rear shocks with IKON shocks which are fully adjustable and rebuildable, these shocks have made a remarkable difference in both comfort and handling here's hoping Triumph has fixed the stick in gear problem?

    Sorry to say, but I feel your pain. I have a 2018 T120 Black that was in the shop for 5 weeks due to the same issue. Riding fine, then all of a sudden would not downshift. At the time, I only had 2080 miles on her. Got covered under warranty, but now with less than another 1000 miles on her (odometer now at @ 3050), the same issue. Won't downshift from 5th. Back on a flatbed and back to the dealer. This is really pissing me off. Clearly, based on other forum posts, this is a recurring problem. Supposedly Triumph upgraded one of the parts to try to address this, but based on my experience the new part is not any better than the old part (maybe worse). Hoping that they can get it resolved this time.
