I first purchased the Motech Alu-rack and Givi adaptor plate thru Twisted Throttle. Was very disappointed with the way it crowded passenger and had no adjustability. Sent it back maybe three weeks ago, still haven't received any confirmation that they received it and credited my card. I had sent an e mail questioning whether they were going to charge me a re-stocking fee. Their answer was that they had a number of returns that they hadn't gotten around to processing. Bottom line: buy the rack form AmotoStuff, similar quality with considerably more room and adjustability for passengers. I don't feel that Twisted Throttle was very accurate in their description of Alu-Rack. Check out California Sport Touring. They actually say they don't reccommend AluRack if carrying a passenger. I suspect Twisted Throttle has seen the last order from me.
