Yamaha 135LC, also known as Yamaha Spark 135 in Thailand,Yamaha Sniper in Philippines Yamaha Jupiter MX inIndonesia and Yamaha Exciter in Vietnam, "Yamaha T 135 Crypton X" in Greece is a small underbone bodied motorcyclemanufactured by Yamaha Motor Company which is also a mopedor underbone model with the second-largest displacement behindSuzuki Raider 150. Powered by a liquid-cooled 135cc 4-strokeengine, the Y135LC is specially designed by the parent company in Japan for Southeast Asian market.
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[1].

FEATURES
- DiASil (die-cast aluminum cylinder) which has better heat conductance to dissipate excessive heat easily.
- Lighter forged piston
- Roller bearing rocker arms with less friction than typical rocker arms.
- 4-valve water-cooled engine - The 4-valve engine configuration provides better volumetric efficiency compared with other 4-stroke moped models which uses 2-valve engine design, enabling the engine to produce higher torque at high rpm. However, the engine displacement of 135cc limits the ability of air-cooling system while retaining the small kapchai design at the same time, therefore water-cooling system which has better cooling efficiency is used.
- Fuel injection (2008 Yamaha Spark 135i in Thailandonly) for less dirtier emission and better efficiency than the carbureted version.
- Carburetor with throttle position sensor and accelerator pump (other countries) - The Y135LC usesMikuni VM22 carburetor equipped with throttle position sensor for more precise ignition timing, increasing the engine's efficiency, and also an accelerator pump for better acceleration and instant response during take-off.
- Catalytic converter - Even though most 4-stroke kapchai models are capable to surpass strict emission standards without even using the catalytic converters, Yamaha has taken an initiative to install a catalytic converter to the Y135LC to surpass even stricter emission standards in the future.
- Sport rims with tubeless tires (standard for Malaysianmodels only)
MODEL HISTORY
The Yamaha Y135LC debuted in 2005 for Thai and Indonesianmarket before brought in Malaysian market in February 2006. The Y135LC was designed by the headquarters of Yamaha Motor Company in Japan for Asean market. The model was very successful in Southeast Asia especially in Malaysia.
