Suzuki RF series

The Suzuki RF series are sport touring motorcycles that came with 400 cc, 600 cc and 900 cc engines and were in production from 1994 to 1999. The 600 and 900 are based on the GSX1100R bottom end, a 16-valve inline-four, four-stroke, water-cooled unit with smaller carburetors and valves for smoother power delivery, canted forwards 19 degrees in the frame for a lower center of gravity. The 400 uses the engine from the GSF400 with 32 mm carburetors. The 900 has a five-speed gearbox and the 400 and 600 have six speeds. A U-shaped water-filled radiator lets the engine sit low, and the bike has no fuel gauge but a fuel low light and a 4 litre reserve.
