LC 135i EXTREME SPIRIT
Yamaha is known for their innovation and their radical ideas presented on their bikes especially for the underbone bike such as the popular LC 135. This bike has its own aura since it is the only bike in underbone category that is equipped with 135cc engine. In this world of rising fuel prices, LC 135 really makes sense with the performance it can offer from the big engine and fuel economy from its 4-stroke type of engine. If you are looking to get the best bike that offers both, I think there is no other than LC 135 that can beat this.
Rumors have been talked a lot in many forums that I have read that says that there will be a new model of LC 135 with manual clutch and also fuel injection! I think this can be true because the LC 135 ES is long due. The stripe and design haven't yet been refreshed and updated until now. We know that Yamaha likes to change their model a bit by bit until they get a really perfect bike. This is proven with the RX-Z. RX-Z has started from the previous model of RX-S 115, and at that time it is only 5-speed transmission. The design of the exhaust pipe is still old school where Yamaha designed a straight type exhaust without a resonance chamber. Fast forward to 2006, we can see RX-Z have changed into a new menacing beast with a heart for environment where we can see catalyst equipped exhaust, 6-speed transmission, new design for head and tail lamp, better clutch design and many more changes from the previous RX-Z model that was launched in 1980.
So, is LC 135 ES with fuel injection coming to Malaysia? Probably yes. Let us look in terms of the design of the engine. LC 135 and Yamaha's fuel injected bike, FZ-150i, share the same engine design. It is made from same cast and also they both used DiAsil cylinder. The differences can be seen only in the engine block component where LC 135 is made to handle 134.7cc of engine block and FZ-150i is made to handle 147.0cc engine block. So, in terms of placement of the fuel injectors to replace the carburetor, it is no problem since Yamaha can just borrow the fuel injector design from FZ-150i to be fitted to LC 135.
Then, what happens if this is true? Well, the LC 135 will have a more accurate fuel and air mixture. This will reflect to better combustion so, there will be less smoke, more power and better fuel economy! Also fuel injection engine will give a better throttle response to the biker since it is electronically controlled (means that there is ECU). You can also do your fuel mapping by your own if you can change the ECU to a custom ECU. Woahhaa, there is a lot of possibilities waiting for us if this can be true.
Well, what can we conclude? We hope this can be true. And if this is possible and true, we will have a new bike named Yamaha LC 135i ES.

YAMAHA LC 135-the maddest,wildest,coolest bike ever!!!
Yamaha 135LC, also known as Yamaha Spark 135 in Thailand, Yamaha Sniper in Philippines Yamaha Jupiter MX in Indonesia and Yamaha Exciter in Vietnam, is a small underbone bodied motorcycle manufactured by Yamaha Motor Company which is also a moped or underbone model with the second-largest displacement behind Suzuki Raider 150. Powered by a liquid-cooled 135cc 4-stroke engine, the Y135LC is specially designed by the parent company in Japan for Southeast Asian market.
Take the LC135 out on the streets and you are convinced anew that this is a different kind of machine by its ride. The sharp acceleration it gives you starting out from a
traffic light, the smoothness of the power development through 2nd, 3rd and into 4th gear. You can almost tell from the engine sound how efficiently the fuel is being burned
and you feel the joy of handling such an efficient machine.
If you are running at about 20 km/h in top gear, you will find that you can accelerate smoothly without downshifting. You feel the power develop rapidly as you accelerate.
This is the moment when you appreciate the extra power of the 135cc engine. And when you are running at over 20 km/ in 4th gear you may feel the kind of ease that makes
you think you are on an automatic transmission model.
There is also a sense of assurance in the predictability of the relationship between engine rpm and motorcycle speed that frees you from unnecessarily bothersome gear shifting.
You will be surprised how low you can let the speed drop while staying in 4th gear and still get powerful acceleration without downshifting when you decide to pick up speed.
On the other hand, this is a machine that is fine-tuned to handle more aggressive, sporty riding with precisely timed gear shifting.
When you downshift from 4th into 3rd at about 20 km/h and open up the throttle, you will experience a whole different world of performance.
With the sharp burst of acceleration you get, you pull away from the car that had been running beside you and watch it get smaller and smaller in the rear-view mirror.
For this kind of performance you can thank the LC135’s new 4-valve engine with forged piston and the TPS carburetor fitted with an accelerator pump.
This is not just a matter of what is normally called “good response.” If response is too sharp it can lead to jerky performance that is difficult to control.
What the LC 135 boasts is an acceleration feeling that is just nice.
In 2008, the fuel-injected version of the Yamaha Spark 135 was launched for Thai market, making it the second underbone motorcycle using the fuel injection system after the Honda Wave 125i
