150cc Supercub (underbone sport moped motorcycle) segment has a new challenger in the form of Benelli RFS150i.
It is powered by a liquid-cooled, with four-valves, B3SP three spark plug, single-cylinder SOHC, six-speed 149.8cc engine. RFS output 15.5hp at 8,500rpm.
The RFS has a couple of uniqueness which no other moped has which is a ‘3-Spark’ system uses the three spark plugs. Why does a single cylinder bike need 3 spark plug? Benelli claims that the three spark plugs will ensure an even and complete detonation of fuel, which means better performance, efficiency with lesser environmental impact. The engine performance could be better if the RFS’s ECU is not restricted as we found out that the RFS has a restricted top speed of 135km/h and has an rpm cut at 9,000 rpm at all gears. Most manufacturers now do have restrictions. A rev limiter in an ECU limits the RPM’s so the user will not damage their engine by over revving it and having a valve to piston contact, an event which is catastrophic. Overall the engine is pretty smooth and comfortable for city riding. While during the review period we rode to the back roads to Genting Highlands the speedometer will dip plus minus 10km/h while full throttle from flat roads to slope roads. RFS fuel tank can accommodate 4.8 litres of gasoline (largest in its class) and with my full throttle, it can only survive at most 120 km mileage before the RFS fuel indicator start blinking. But I’m sure, if you’re more relaxed riding a better fuel mileage can be obtained. The part I dislike is the refuelling part as the handle needs to be locked to open the seat for refuelling it does take a bit of force to open and close the seat!
The other uniqueness of the RFS is the only moped fitted with 41mm race-type inverted front suspension as standard. This is the first time that a moped is offered with this suspension set up. The inverted front suspension has an 88mm of travel, while the rear KYB monoshock gives a 27mm of travel. The chassis is made up of a straddle type frame that gives the RFS a slim and sporty look. The straddle frame give the RFS a solid feel. Handling of the RFS overall felt soft at the rear, and lacks the feel and grip from the standard Komodo tyres. Weigh in at 115kg the RFS does feel light.
The meter panel is part analog and part LCD while the front headlight features integrated LED daytime running lights.
