I-BUS N-26 / N-32

The 450 Series is built on the ISUZU 450 Truck Chassis with a full walk-through bus body. This front engine bus is suited for rural and city bus operators providing better handling capabilities by having more weight transferred over the front axle. This model retains front driver’s door for better access, and has a great power to weight ratio. The 450 Series Bus can be custom made to suit various seating capacities from 26 to 29 seats including driver and has rear spring suspension with 6 Speed Manual or AMT (Automated Manual Transmission). Driver comfort is maintained with all standard ISUZU equipment used within the cabin.
