my understanding is we are standard i.e. the same as a harley. i used a little "indian" speedo ($50 off ebay) before it ate my speedo cable (my fault, mounted at too great an angle) and then i went with the dakota digital hly-3013 (which i did a write-up on, search for hly-3013). i'll sell the "indian" speedo for $25 including shipping if your interested.
