LAS VEGAS — Honda got two for the price of one at the 2008 SEMA Show with its 2009 Ridgeline Powersports concept. The vehicle links the Japanese automaker's truck and motorcycle business since the Ridgeline hauls a Honda CRF 450R Special Edition bike.This concept 'represents what Ridgeline owners could build using currently available Honda Genuine Accessories,' the automaker said in a statement. Unfortunately, two of the coolest accessories are not available. They are the black experimental-finish 18-inch wheels and grille surround.Other details include a bed extender and motorcycle wheel guide.Inside Line says: Time to get those black experimental-finish wheels into the accessories catalog. — Anita Lienert, Correspondent
