From ElgrandOC Wiki
E50 Rider came with an updated exterior, including 16" 3 spoke chromed Alloy Wheels, a full chrome upper and lower grille at the front, unique side skirts, unique lower fitting rear bumper and spoiler. The interior also benefits from full leather seating.
Due to the expense of fitting the exterior, the basic spec level is actually less than the E50 Highway Star, but all specs were still offered as optional extras. Often, Rider's that are imported are usually very high spec.
