My ducati monster is a 2006 vintage and I've owned it since 2008. It's an old bike but it's still a blast to ride, except it's starting to break down after all those years. About 8 years ago, I took the bike on a track day and crashed out. The speedometer was never the same after that and 3 years ago it finnaly gave up and I've since left it to a state of disrepair. Today though, I opened her up and decided to figure out what's wrong.
Stepper motor number X15-689 was damaged and needed replacing! A little bit of research found that the stepper motor has been updated and superceded by X27-689.
It wasn't a hard part to find, except it's going to take 3 weeks for it come from China! Cost? $8.00 each. There are a few USA sellers, but their charging $20 each and I need two of them. Oh well, I've got a transmission to install in my bmw, so I don't have much time to ride anyway!
