Mechanically, the car is virtually identical to the first-generation VAZ-2101, featuring the Fiat-derived manual transmissions, coil spring suspension all round, and aluminium alloy drum brakes with cast iron brake shoes on the rear wheels. The smaller-engined variant, the version (VAZ-2105) had a revamp of its inline four-cylinder compared to the original VAZ-2101 (Lada 1200). The old OHC design had its camshaft driven by chain, while the new one had a toothed belt drive. Some modifications of the Riva's larger-engined version (VAZ-2107) carried on with the chain-driven OHC engine coming over from the original Lada 1500 (VAZ-2103), while others had a later 1,6L VAZ-2106/21067 engine. Another change was made to the engine in 1992, when single point fuel injection and catalytic converters were specified to keep up with emissions legislation.
