    So I have made a business fixing and customizing bikes and sometimes something unusual rolls in shop. Today a guy dropped off a Honda transalp. Original owner with 16000 miles....it’s a really cool bike! He wants a master cylinder rebuild.....problem is I can’t find a rebuild kit for this bike anywhere. Any ideas? If it really comes down to it I might have to get him a comparable used master from another bike and rebuild that.

    also I’m wondering if anyone can tell me when these were available in the us. This ones an 89 and Wiki just says that’s a year they were available here but doesn’t say anything about any other years. Anybody know that one?

    Available in the US from 89-91, only difference was color with the white 89s being the most common. Europe got them far longer with a few significant changes over the years

    lots of experts there to answer questions. There's also a link somewhere in there to the downloadable maintenance manual, well worth it.

    I just ordered a master cylinder rebuild kit from Brake Crafters and Mark just put the rebuild kit on their website (November 5, 2020). According to Mark, Honda made two different piston sizes for the '89 and '90 Transalps, an 8.6mm and a 10mm. He sent photos of how he determined which fit his bike (yes, he has an '89) and when I measured mine, it was a 10mm as well.
