I’ve had my Street Triple RS for 3 years, and after about 5k miles (10 months), the quick shift stopped working. It was replaced under warranty, but less than 2 years further on, it’s now at just over 10k miles and failed again.
Down shifting works fine, but up shifting doesn’t. For the last month or so it has been random each time I started the bike. It would either work fine for the entire trip, or it wouldn’t work at all for the entire trip, which led me to think it’s something electrical rather than mechanical.
I have no idea how these things work, but are there any simple things I can look for, such as connections or fuses? I also have a diagnostic tool, but it didn’t show any error codes.
If it was replaced under warranty, would that reset the warranty period on that part, or is it just tough that it can’t last 2 years?
