Advantages of the New Fuel Injection Engine
A new fuel injection system has been designed specifically for this model and to accommodate it the designs of the manifold and fly wheel magnate have been optimized. In combination with Yamaha¡¯s Air Induction System and the catalyzer, this new system provides numerous advantages.
1) Environment-friendly performance at half the levels of Taiwan¡¯s Phase 4 emissions standards
The MAJESTY 125FI achieves emission levels for CO, HC and NOx that are half or less than those specified in Taiwan¡¯s Phase 4 emissions standards set to go into effect in June of 2004. (The Phase 4 emissions standards are based on cold-start mode that is said to be difficult to deal with simply by exhaust treatment measures.)
2) 39 km/liter fuel economy (CNS mode)
The adoption of fuel injection makes it possible to optimize injection pressure, volume and timing in accordance with engine rpm and running conditions and thus achieve 39 km/liter fuel economy (on CNS mode). (The existing model gets 36 km/liter.)
3) Excellent starting performance
This model achieves outstanding starting performance at high elevations, at high and low temperatures and after the machine has been left unused for long periods.
4) High level of drivability (machine running performance)
The optimal control of the air-fuel ratio made possible by the fuel injection system ensures excellent drivability, good acceleration, excellent performance stability at high elevations and steady idling performance. This means steady cruising performances at higher elevations that can reach 2,000 meters in Taiwan.
Main Features from the Existing Model
1) Highly reliable liquid-cooled OHC single-cylinder engine and V-belt automatic transmission
A liquid-cooled OHC, 124cc single-cylinder engine characterized by torque-y performance and quiet running is adopted. In combination with the V-belt automatic transmission it provides spirited running performance and good acceleration.
2) Generous-dimension chassis design for enjoyable cruising
The body that give this model its excellent handling stability and riding comfort is built around a specially design frame that draws on technologies used in the 250cc Majesty model that is so popular in Japan and Europe. The combination of an optimum frame rigidity balance, the long wheelbase and wheels mounting12-inch tires front and rear give this model a truly stayble ride with very neutral handling. The aerodynamically designed cowling also adds to the riding comfort.
