Reed-valve induction is designed to increase the efficiency of a two-stroke engine. Unlike the regular piston-port system, the reeds act as a check valve: they let the air-fuel mixture into the engine and prevent it from blowing out back to the intake when the piston is going down. Such valves can be found in motorbikes meant for racing, scooters, ATVs, snowmobiles, and personal watercraft manufactured by renowned companies starting in the 1970s up until now. However, using reeds on public roads is usually prohibited.

In a common case, the reed valve consists of two or more flexible petals mounted onto a wedge-shaped block, a so-called reed cage. It's typically mounted between the engine and carburetor, but there are also various schemes in which the assembly can be bolted to the crankcase, like in some motors by Polaris and Arctic Cat, or to the cylinder, like in several models by Yamaha or Rotax. The shape, size, and material of the petals may differ. Nowadays, they are usually made of carbon fiber or fiberglass and can serve long, but still, time takes its toll on them.

Worn-out reeds tend to stay partly open, and this may result in hard starting and bad acceleration. To successfully resolve any motor-related issue, visit our online store. We carry a wide range of reed valve systems, repair kits, gaskets, and other components by such market leaders as Moto Tassinari and Boyesen. Possessing a rich experience in this area, these companies implement different designs to improve throttle response and torque throughout the whole RPM range. For example, Boyesen is known for its dual-stage system in which one petal lays over another one. Moto Tassinari often prefers multiple and somewhat shorter petals. If you need help to make the right choice, contact our specialists, but whatever you pick, you will end up with the product of premium quality.
