The power plant of the 2005 Katana remains true to the Suzuki sport bike tradition. A 600cc, liquid cooled, inline four cylinder, boasting sixteen valves and electronic fuel injection, delivers a throttle response that is typically reserved for sport bikes, and high-end sports cars. The engine symmetry is near perfect. It turns runs smoothly in all RPM ranges, and offers surprising power at any range. Blast away from slow moving traffic or from a standstill, and this bike will achieve the legal speed limit and beyond with a few clicks of the gear lever. Working rapidly through the six speed transmission may become a daily task for the more adventurous riders. The 2005 Suzuki Katana 600F's top speed is listed at 138 mph—more than enough for any rider to catch a thrill, and potentially attract a few law enforcement officers in the process.
