High-quality 43 mm tuning set with 57 cc suitable for your moped / moped with Sachs 503 2AL, AAL, 2BL, ABL CH engine.
The GPO Pomodoro racing kit is currently one of the most powerful cylinders on the market and impresses with its high torque in the lower engine speed range, powerful acceleration and constant power delivery right up to high engine speeds. The optimized internal design ensures ideal flow characteristics and enables an efficient supply of the petrol-air mixture, which guarantees an evenly strong power build-up. The result is a tuning cylinder that gives your engine a clearly noticeable increase in power and ensures indescribable, dynamic performance on the road.
Due to the correct angle of the intake port and Ø 19 mm bore, both original and swiing® brand intake manifolds and carburetors fit under the side skirts without the need for adjustments. With a 45 mm diameter cylinder neck, no spindling of the engine case is necessary.
The GPO piston improves intake timing, resulting in higher engine speeds. The edges of all ports are smoothed, which enables optimum mixture flow.
