The MT-09 SP features a newly developed 890cc liquid-cooled 3- cylinder, DOHC, 4-valve-per-cylinder fuel-injected (YCC-T) engine with a downdraft intake. The bore × stroke of 78 mm × 62.1 mm and 11.5:1 compression ratio provide outstanding torque with strong power delivery characteristics. Almost all of the fundamental parts of the engine, from the pistons and connecting rods to the crankshaft, camshafts and crankcase, have all been redesigned with a reduction in weight. The combination of improved combustion efficiency and lighter weight results in an impressive fuel efficiency of 49 MPG.
