in my case it depends, if I need a 5,000 service and then a 10,000 and another 5,000 service it runs about $800.00 to $1,000.00 a year, if I start with a 10, go 5 and another 10 it cost a little more. then I usually need at least one new rear tire but if I need two then I need a new front..so it all depends on how much you ride..and before anybody jumps me about doing my own services, i did that for 40 years, I just want to turn key and go, leave the service work to the Mechanic, he needs the job
services cost money if you have the shop do it, I also recommend doing as much as you can yourself, it will save you some, just don't re-nig on the work, follow the book, lube your cables, change oil and filter, don't cheat yourself, do a good job, it pays in the long run, I have today just rolled over 142,000 miles on my bike, no major problems, just routine repairs and replacements..

oops sorry, this is the dyna side, well I;ll do the same with my FXD to..sorry about that.
