Honda Rebel 300 & 500 General Discussion
There's this one: Motogadget Chronoclassic Tachometer - RevZilla
I like the design, it has no reviews and no Q&A though so I'm not super sure about it.
then there's this one: Hardline Hour Meter / Tachometer - RevZilla
Which isn't a speedo/odo/tach dash and is just a(really) small LED screen...
