Styling:

Chopper-inspired styling with a raked-out front end, taller handlebars, and a prominent 'Gullwing' front fork. Distinctive 'Wide Glide' front fender and often custom-style tank and seat.

Engine Platform:

Part of the Dyna family, utilizing the well-regarded Twin Cam 88 powertrain.

Ride Quality:

A blend of cruiser comfort and more responsive handling due to the Dyna frame geometry, although the extended wheelbase of the Wide Glide emphasizes stability.
