Description

KAVZ-4270 is designed to operate on routes with a high passenger traffic. The bus is equipped with YAMZ and Cummins engines.

Passenger compartment accommodates 28 seats, including one for passengers with reduced mobility. Air suspension provides comfort during the trip due to a low ruggedness and natural frequency.

Kneeling system (an adjustable bus tilt up to 7° towards the doors) provides a minimum slope to make the boarding comfortable for all passenger categories.

Along with high environmental performance the bus has high economic parameters: reduced operation costs owing to a low cost of gas fuel.
