This is the information on the HD FLHRC (Road King Classic):

I replaced white wall tires with black walls late summer last year.

1998 Road King, 28K miles, K&N Air Filter, Custom Cam, Power Commander (fuel flow control), Fuel Injected (great when running in the mountains - automatic adjustment for atmosphere change), dual brakes in front. Two Seats: original seat and back rest (detachable), plus Corbin seat (pictured on bike) with back rest that can be used for passenger or moved to driver position, detachable windshield with AM/FM/Cassette Radio (that can be detached from windshield if wanted), heated grips (great in cold weather). Excellent bike, has always been reliable.

Bike has trailer hitch, however I have never pulled a trailer with this bike, I kept it on the bike as added bumper when another bike bumps your fender, or when backing-up it is added protection.
