For god's sake don't buy an SP-1!
I wanted to get a duke in 2001 and was talked into buying a new SP (mainly by the price) instead.
The SP is a track bike, pure and simple. It is far too stiff for the road and every ripple / catseye sized thing will have you out of the seat.
Lumpy B-roads are out.
The fuelling is crap and they only do about 35 to the gallon, or less if you start pushing on.
The build quality is good, the engine is powerful and gets more so after 8k miles, but like all of the H****s, the soul of the bike has been engineered out.
It's like riding a plank of wood.
Buy a Duke carefully and you won't regret it, or stop grinning when you're out on it.
Biking is a touchy feely thing after all.
