Novarossi BONITO.21-7XLB 7 Port .21 Engine
Ref: NVBONITO.21-7XLB
This is the Novarossi BONITO.21-7XLB 7 Port Competition .21 Off Road Engine. Based on the Toro-Nero engine, Novarossi found room for improvement through a variety of subtle changes and developed the BONITO.21-7XLB. The Bonito features the redesigned 'Lighter & Lower Evo2' type cooling head that lowers the center of gravity of the engine and chassis, as well as improving cooling efficiency. Revised porting provides more linear bottom end power than the Toro with the same incredible top end delivery, while the piston design features Novarossi's 'Compact Combustion Technology', providing increased efficiency. The crank spins on a high quality ceramic rear bearing that was selected for improved performance and lifespan, while the backplate has been updated with a steel insert for reduced conrod friction and extended conrod life.
