Purchased a Bakup backrest for my 08 Strat. Cost was a little less then $300.00 shipped (little cheaper on E-bay). Came quickly. Very easy install, took about 20 minutes (if that) using stock hardware and their kit. No cutting of the pillion seat like the Utopia.
Impression - nice quality backrest. Matchers the bike well. It is fully adjustable and fold forward for passenger ease of getting on the bike. Feels great, and provides good solid support.
Negatives: few, and they are sort of nitpicky. Backrest comes with a vinyl cover that covers the folding/adjustment mechanism..once pulled into place the rest can't be adjusted with out pulling the cover up. Cover doesn't quite cover all the adj. mechanism. Backrest is not quickly removable.
Would I recommend - you bet! Nice product.
