2012 Motor Trike GL 1800 Adventure IRS, New Goldwing w/ Motortrike Adventure IRS Kit!!! - This new IRS suspension is so special that it called for the development of a new body. Look at the size of the rear door (three full-faced helmets will fit). Notice the trunk hinges do not interfere with the interior luggage space (no scratched helmets). Also, note the trunk light mounted on the door so it lights up the trunk (Standard equipment / no charge)!
