no, it is all stock. Happy for You! Whish You have fun with it! ;)

HI there! I had this bike for over 19.000km, and had no major issues. Some minor ones that I had: -after a few hundreds of kilometers I had to change the battery (don't know the exact reason, maybe the disributor didn' t kept in good shape, or I also may have been of fault, for starting the bike and no riding it, just for sound check) After I got a japanese (Yuasa) battery all was good. Besids that just the usually chain loose which was solved at oil changes. I never road it with passenger, so I don;'t know about that part. What I would recommend is to check with some local distributor and take the bike for a test ride. Wish You many safe kilometers with any bike You finally choose!
