In places you can see where Kawasaki have tried to save money on this bike, as it is a bit plasticky but it is cheap to buy. Fuel efficiency is excellent, 55 mpg around the city, and my tyres are still in good condition after 8000 miles. It is extremely nippy. It has a 6 speed short ratio gearbox that accelerates to 100 very quickly without wanting to wheelie, however I often try to find a non-existent 7th gear even at 50 mph. In the traffic light GP, I have never been beaten. Audi RS6, Lamborghinis and BMW M5s have all been trounced... and they were pushing! Taking the bike past 7000 revs is like entering Hyperdrive or Warpspeed. If you have one of these bikes I seriously recommend changing the exhaust to a Scorpion (road legal), it makes a great noise also making the power delivery smoother, greatly increasing the low end torque... and what a noise it makes without the baffle! Of course I only put the exhaust on for the increased fuel economy, honestly guv (over 185 miles for a tank of V-power petrol).
