Top speed in specs are wrong, so is the horse power and tork ratings. on dyno it produced 101 horse power on 92 ft pounds of tork. Last night mine buried the needle going up a mountain @ over 140 . Don´t know how fast it really is. I absolutely love this bike. I have been riding bikes for over 35 years and have owned at least 20 bikes. I also have been a mechanic at 2 different motorcycle shops. Have ridden everything from scooters to hyabussa´s , The s3 has become my favorite sport bike.
