The KEIHIN PWK flat slider series belongs to the absolute high end of carburettors. Extremely high quality and produced with minimal manufacturing tolerance level they are currently second to none in terms of quality and performance. YAMAHA has also decided on KEIHIN as an original equipment manufacturer in the area of PWK carburettors. The individual carburettor ranges can generally be delineated very easily and also set up with high precision. The KEIHIN PWK therefore responds quickly to throttle adjustment and delivers a solid performance across the entire rev range. This not only means it is the first choice in the area of motor racing, it is also indispensable for high performance tuned road engines either side of the 30 PS mark.
