Features
Riga-11 is a moped that had certainimprovements compared with previous similar models. The spinal frame consists of a central tube, to which the clips of the front fork, motor and some other parts are welded. She became more rigid and hardy. The considered Soviet moped became the first modification equipped with a spinal-type frame.
The weakest link in the design of transportmeans of steel wheels. However, compared with the seventh variation, they received an enlarged cross-section and did not deform so quickly when driving on rough roads with potholes. The wheel design itself remained unchanged.
High wheel provides a comfortable fitdriver, 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 on the levers are equipped with tips in the form of balls that protect against injury from falling.
Device other nodes
Improved saddle device.His box has become more powerful, and also increased the thickness of the pillow. Such a decision made it possible to make the driver’s landing more comfortable and to increase the storage space for the toolkit. Seat spring is fixed by new elements that ensure the reliability of the entire node.
Fuel tank, coupled with the trunk is located inThe back of the moped, forms an impressive platform that can withstand 15-20 pounds of cargo. The volume of the fuel tank is four liters. This reserve is enough for about two hundred kilometers.
Thanks to a solid reserve course "Riga-11" -moped, which has become popular both among urban residents and in rural areas. The engine remained the same, but the chain is made in a new, more durable and durable version.

Spare parts for mopeds "Riga-11"
Consumables for the equipment in questionNow find quite problematic. This applies to original parts. Analog variations really pick up or order, because they are simple and unpretentious.
During the serial production of a mopedelements were available in sufficient quantities. Many users went through the engine and other components themselves, trying to improve or repair them. It is quite capable of a person who has minimal knowledge about the structure of two-wheeled units.
