I rode a new version Interceptor 800 and was dissapointed. The gearing was too close and the final gearing was so long. And the engine will buck and refuse to pull below 4,000 rpm so that you were forced to clunk down into first when turning onto a different street. Very surprised at the engine bucking from the V4 engine which people romanticize about. A Ninja 650 is much more pleasant to commute on and will pull smoothly from 2,500. And the V4 throws off a ton of waste heat. It will cook you at a stop light on a hot day. Which is telling me that it will not be very fuel efficient. It is a cult bike for sure and has the 4th most Fuelly accounts. Averaging 40 mpgUS.
