I had a 2008 BC WT Turbo, and the ride is super comfortable, with perfect seating position, you will not get tired riding that sled. I now have a 2009 spar-chassi BC, which has better steering. I had the turbo version of the 2008 660, and when it kicks in, it felt alot "torque-ier" than the 2009 1100 N/A-engine. The 660-turbo had quite some turbo-lag however, so if you are pulling alot of weight uphill with some technical turns, beware that if you let off the throttle, you lose half the HP`s until the turbo kicks back in.....
