Yamaha Sniper 135

• 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-st
  roke 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 Thailand o
  nly) for less dirtier emission and better efficiency than the carbureted version.
• Carburetor with throttle position sensor and accelerator pump (other countries) - The Y135LC uses Mikuni 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 Malaysian models only)
