The 180° piston ported two stroke twin was of unit construction and had alloy head and alloy barrels with cast iron liners. The T20's bore was increased 6mm to whilst the stroke remained at giving a displacement of. The engine had the compression ratio reduced to 6.7:1 and heavier flywheels than the T20 to aid low speed tractability. Claimed power output was @ 7,500 rpm, giving the machine a top speed of.Fuel was delivered by twin 32 mm Mikuni carburettors. The engine was lubricated by the Suzuki Posi Force system which injected oil to the main bearings and conrod journals.
