I just installed my new backrest on a 2000 Honda Valkyrie, and completed a test drive. What a great backrest! The comfort and support were great, and really improved the enjoyment of the ride! The quality and craftsmanship of the backrest are outstanding! The installation took ~ 5 minutes, with no modifications to the frame or backseat. I really like the adjustment set screws to fine tune the position of the backrest. The crew at Utopia exceeded my expectations, and manufacture a great product! Many thanks and God bless you all!
