Yamaha Motor Kencana Indonesia YIMM has launched an all new Jupiter Z1 which is the upgrade from the original Yamaha Jupiter Z 115 (or also known as Lagenda 115Z in Malaysia). This is definitely an all new machine that is equipped with new fuel injection engine. The engine not only gets an upgrade on the fuel delivery but also on the inside of the engine. It features the technology from Yamaha racing knowhow that is YZ Crankshaft Technology, Low Friction Technology and Forged Piston.

The crankshaft are taken from the technology of YZ450F which is a trail bike that contain a lot of torque. Low friction technology are used to minimise the friction so that the power are not wasted and delivered to the power train with minimal power loss.

One of the proven technology from MotoGP is the use of the forged piston. This kind of piston has high material durability and at the same time is lightweight. In the end, the piston are able to deliver the massive power from the engine and making the bike is much more easier to be accelerated.

What surprise me is the 20% power increase claim from the previous version of the Jupiter Z115. 20% is in fact a big increase, but with the available technology fitted to this bike, I think it is achievable. The current version of the Jupiter Z115 produces 6.0kW, so based on my calculation the Jupiter Z1 is at 7.2kW. The current top speed of the Jupiter Z115 is 110km/h, so again I’m calculating that this Jupiter Z1 should be able to get 132km/h. All that are based from my calculation and not tested on the road.

This is really what I expect from one of the top bike manufacturer in the world. Improvements, green technology and at the same time still capable of producing of fun and high performance bike from a small engine.

  1. I’ve this Jupiter Z1 right now. Acceleration is really good compared to my old 2008 Honda 110 cc but I prefer old Jupiter (carburettor) sporty design for side lamp and instrument cluster/speedometer.

  2. maaf sebelumnya, YMKI sekarang bersatu dgn YIMM (dulu YMKI pemasaran, YIMM import & perakitan) utk efisiensi kedua perusahaan tersebut bersatu pada awal 2012.
    btw, saya pembaca setia anda dari Indonesia 🙂 keep up the good work!

  3. Am have check the bike spec at Yamaha Indonesia URL.

    Power: 7.4KW aka 10.06hp /7750rpm
    Tork: 9.9nm / 6500rpm

    Compared the current one in MY

    Power: 6KW aka 8.2hp / 7500rpm
    Tork: 8.3nm / 5500rpm

    Huge improved based on calculation 115cc class

  4. malaysia’s motorcycle scene is just dismal. yamaha under hong leong is happy
    just to sit on its arse and not do anything that might rock the boat. the LC is a great
    commuter bike, no doubt, and the FZ is good for longer haul but if you want
    excitement, forget about them.

    250cc pon tadak. r15 pon tak nak bawak masuk. boring betol. only kawasaki has
    a bit of a spark. hopefully SYM will start to become a bigger player.
