I too have had 2 1050 STs...yes its a great bike, and handles much better than it may appear. I had no trouble getting my knee down on them.I never trackdayed them cos the thought of smashing all that plastic if it went wrong ( and not be insured) stopped me doing it.Ultimately a stock gen1 has a bit more bhp ( mostly top end) but the sprint does have a lovely grunty motor- about perfect for road riding at up to sportsbike intensity. It was never designed to keep up with gixxer setc, but can do surprisingly well. If it had an achilles heel , it was the slight top heaviness and slow steering in tight alpine hairpins.But I would have another 2 moro, as it is a very comfy capable bike, superb at the job it was designed for.
My 1st sprint went to make way for my FZ-1 which didnt stay too long, and I bought another sprint ! lol....but I sold that sprint in 08 for a CB1000R , as I had bought a gen1, spent all the cash on all the necessary mods, and it seemed odd to have 2 sports tourers in me garage.I now have a speed triple alongside the fazer, but tbh I think a sprint would still have been worth keeping.But if you R going to run 2 bikes, IMO they should offer diffrent riding experiences.I kept the fazer over the sprint for quite small diffrences- fazer bit more powerful, though less comfy; sprint not quite so agile as my K tech suspended fazer . Very small reasons indeed.
