The SM 610 IE now has an electronic injection system that was developed in collaboration with Mikuni.
The exhaust system on the four-stroke single cylinder engine has a “closed loop” lambda probe. The catalyser has been redesigned and optimised to meet Euro 3 requirements. The catalyser section on the silencer and the area around the passenger footrests have been covered with stainless steel protection.
The engine now features a 42 mm throttle body with the starter command on the handlebars and there is now a 300 Kpa Mitsubishi “twin jet” fuel injector fitted to the throttle. The pressure regulator (3 Bar) regulates any return of excess fuel to the tank and the MAQS (Modularised Air Quantity Sensor) consists of air temperature, mapping and TPS sensors (Throttle Position Sensor). The Kokusan 360W three-phase ignition flywheel is also new.
The water temperature sensor is positioned on the head. The injection ECU processes signals and governs the operation of the solenoid-operated valve fitted to the right hand side of the radiator. New components include the rugged polyethylene petrol tank with a 40l/h pump; the non-return fuel circuit has quick-fit connections.
The rear mudguard has a new separate number plate carrier with an independent illumination light.
The saddle has been redesigned and has new padding to improve both rider and passenger comfort.
The chassis can be fitted with a main stand that is available as an optional extra.
