But of course you're talking about an S4R, not an S2R. I disagree with Motoloco on the 800 v. 1000 difference being all that large. Depending on your choices, you can bring the 800 front end either up to (~$1.200) or well past (~$2,000) the 1k's. And in the real world the HP/Torque difference is deminimis, except maybe in high speed freeway passing. The 800 jumps off the line just as quickly as the 1000 (some would say it feels even quicker because of the smoothness of it) and the 1/4 mile times are so close as to not be noticeable by the average rider. The choice comes down to which clutch type you prefer, the vibe level and some additional freeway passing power. My 800 is smooth as silk, never stumbles/coughs/pops, the clutch pull is light and smooth and the slipper action is great. Both are great bikes and the differences aren't as big as the marketing brochure makes it out to be.grazi said:+1. That's why I sold my heavily modded S2R800, when the addition of real suspension (front and rear) and better brakes put the total investment past the price of a new 2007 S4R. That doesn't even mention the power difference, which no sane amount of money could bridge between the 800 and the S4R.
