Alternator Compatibility
« on: February 14, 2014, 09:32:24 AM »
Got offered a 50 amp alternator from a R1150RT.  The numbers on the tag match and it looks like if I replace the pulley with a cup it will fit.  Anyone know of this observation is correct?

98% of all Harleys ever sold are still on the road.
The other 2% made it home.

Checked the BMW part numbers and the alternator is the same.  Think I'll just buy a new cup and upgrade.

Price for a used R1100/R1150 alternator is a heck of a lot less than a K1100
