Adjustable seats only come on the monoposto bikes, not the bipostos. You haven't said which the two bikes are? Do you like it grunty, or more revvy? The chassis' are the same on both (except the '05 749S has the newer style swingarm). I haven't ridden a 999, but I have a 749S that suits me perfectly. I don't need the extra grunt of the bigger engine. Take them both out for a test ride and see which you prefer. |
