Harley Davidson FLHTCU Electra Glide Ultra Classic 2018 Service Manual

Harley’s tagline for the 2018 Electra Glide Ultra Classic is “everything you need for a lifetime of cross-country adventure.” The Electra Glide name has been the choice of riders who want the essential touring machine since 1965, and one ride and you’ll know why. It has the passing power of the Milwaukee-Eight 107, responsive front and rear suspension, Reflex linked Brembo brakes with standard ABS and a powerful LED headlight with spot lamps. The two-up seat has a deep bucket and a narrow neck for rider back support, with a wide passenger area with a backrest and armrests for longer rides, and there’s a Tour-Pak luggage carrier. The infotainment system is the Boom! Box 4.3 as standard, with the 6.5GT touchscreen available as an option. The wheels are 10-spoke Impeller cast aluminum, a 17-inch front and a 16-inch rear.
