Sarkana Zvaigzne, known in Soviet times, is a Riga motorcycle plant specializing in the production of light mopeds. At that time they were one of the best representatives in their category. The eleventh model replaced the seventh series. The only change was the removal of the fuel tank at the rear over the frame, which made it easier to ride downhill. As a power unit, the equipment was equipped with a two-stroke engine with a power of 1.2 horsepower, with a volume of forty-five and a half cubic centimeters. With air cooling of the engine, the device developed a speed of up to fifty kilometers per hour.

The weakest link in the design of the vehicle was the wheels. However, compared to the seventh variation, they received an increased section and did not deform as quickly when driving on uneven roads with potholes. The design of the wheels itself has remained unchanged.

High handlebar provides a comfortable fit for the driver, fastened with a pair of clamping elements with nuts. This solution allows you to quickly and reliably change its position. The clutch and front brake levers are equipped with ball-shaped tips to protect against injury in case of a fall.

The device of other nodes

Improved saddle device. His box has become more powerful, and the thickness of the pillow has also increased. This decision made it possible to make the driver's seat more comfortable and increase the usable space for storing tools. The seat spring is fixed with new elements, ensuring the reliability of the entire assembly.

The fuel tank, together with the trunk, is located at the rear of the moped, forming an impressive platform that can withstand 15-20 kilograms of cargo. The volume of the fuel tank is four liters. This stock is enough for about two hundred kilometers.

Thanks to its solid power reserve, Riga-11 is a moped that has become popular both among urban residents and in rural areas. The engine remains the same, but the chain is made in a new, stronger and more durable version. Due to the wide tires, the motor was shifted to the right of the symmetricalframe points by seven millimeters. This allowed the front and rear sprocket to be in the same plane.
