Yamaha Vietnam has unwraps the cover of the Exciter 150 RC / GP that comes with 150cc fuel-injection SOHC liquid-cooled engine that is the successor of the Yamaha Exciter 135 (135LC in Malaysia, Jupiter MX in Indonesia or T135 everywhere else). There is also a rumor that Indonesia will get this bike with the name Jupiter MX King. There are a lot of improvement of this Exciter RC 150 compared to the Exciter 135.
The first objective of this machine is to ‘boost the feeling of power’ and with that in mind the 135cc engine has been increased to 150cc in capacity to enables it to harness more power. It is also said that the project leader for this Exciter RC 150 is the same project leader who handles the Vixion (FZ150i) development project. Reducing power loss also taken into consideration here with the proven technology that is the DiASil cylinder use to minimise the friction. Also here to minimise the friction is the use of the roller rocker arm that are now being extensively in many small bikes.
Not suprising to us, is the use of FI system to make sure fuel-efficiency for more milease and accurate fuel delivery in high speed for more power when in need. The power rating of the Exciter RC 150 is 15.4PS @ 8,500RPM with the torque 13.9Nm @ 7,000 RPM. All these numbers beat the 1st generation Yamaha FZ150i which also 150cc FI bikes. (more…)
