This is the ABS version. Nice condition and ready for the riding season. The GSX-S1000 powerplant has been refined and re-worked from the mighty K5 GSX-R engine to complement the new naked bike. Basically, it is the same 999cc lump as the 2005-2008 powerplant that got such a cult following, designed to give more acceleration and throttle response. The K5 engine was chosen as it has a long stroke for better midrange than the current GSX-R engine. Bore and stroke remains 73.4 x 59mm, allowing for a compact combustion chamber and flat-top pistons. Cylinder angle is 23 degrees. There are some new parts – such as FEM (Finite Element Method) pistons that are 3% lighter, and new camshafts are designed to optimize valve timing for the street. Iridium spark plugs heighten spark strength and therefore combustion efficiency, contributing to higher power, more linear throttle response, easier start-up and a more stable idle.
