  • Style: The CitycomS 300i modern lines was born from an European Design House. Crafted and balanced with ground breaking technology, sexy design, practicality and economy. And with its new sporty style upgrades, including the brand new design LED tail lights and head light with matte black finishing. There’s no question that it’s also one stunning heck of a ride.
  • New LED Tail Light: Better visibility on the road and use less energy with distinctive new LED tail lights. In addition, the new Citycom S 300i has twin halogen headlights, one low and one for the high beam, offering better visibility and safety.
  • Responsive Performance: New powerful 278cc, liquid-cooled 4-stroke, 4 valve SOHC fuel injected engine has big improvement over the last generation engine. With better fuel efficient, linear power feel that pulls through the powerband delivering excellent acceleration and a sporty ride experience. Right off the bottom the CVT clutch engages and the power is fed to the rear with authority. Twist it on further, and the Citycom S 300i just keeps giving all the way up to 83 mph.
  • Ceramic Coating Cylinder: Ceramic Coating Cylinder is a high-tech product, which applies special compound-electroplating process to disperse SiC ceramic particles uniformly distributing on the cylinder wall. SYM is the first company in Taiwan to make mass production of motorcycle engine by utilizing SiC ceramic coating technique. The Ceramic Sic material can overcome the weakness of general ceramic materials, and in the meantime it possesses excellent properties of high hardness (wear resistance), heat resistance and etc., which can be the best candidate matching the requirements of the engine cylinder. However, general conventional electroplating techniques cannot disperse SiC ceramic particles on the cylinder wall due to the insulation and high weight. As a result, SYM have developed the special compound-electroplating process to disperse Ni particles and SiC particles on the cylinder wall together, which forms a particular cylinder with the compound-electroplating layer (Ni/SiC), and brings the quality to excellence. Currently the quality control of mass production has already achieved to maintain the defective rate below 0.3%, so the ceramic coating cylinder with high quality and appropriate price can therefore be produced.
  • Electric Fuel Injection System - SYMs perfect intelligence EFI Intelligent Injection System utilizes computer programs to calculate the oxygen content ratio in the air and control the fuel emission to achieve complete combustion, full power, rapid start-up, fuel efficiency, low pollution and acceleration enhancement. Particularly in respect of environmental protection, this system can help reduce pollution up to 30% and decrease fuel consumption by 15% without any catalyzer device. SYM's EFI System possesses warm compaction of induction, crank rotational speed, oxygen sensor cohering with the Environmental Protection Regulations, and engine temperature sensor. Collecting comprehensive conditions of the car and roads, it can proceed with precise calculation, and determine a perfect fuel injection volume, air-fuel ratio and ignition timing in order to achieve more powerful energy and less pollution emission, as well as to develop the best performance of engine.
  • High Efficiency 4 Valves Engine: The 4 valves engine mechanism not only increase air intake but also considerably improve engine efficiency over the uneven fuel concentration problem inherent in 2 valves engine combustion chambers to allow more complete combustion and better fuel economy, as well as to effectively reduce noise and exhaust pollution.
  • Safety: Upgraded large dual sport tuned 220mm front and rear disc brakes are impressive and can literally stop you on a dime.
  • Handling: Big wheels mean big handling. 16” wheels just cruise over most of the nasty stuff without transmitting the worst of it through the rider so the Citycom S 300i invariably goes where you want it to go.
  • Instrument Gauges: The Citycom S 300i has a nice dash with a mix of analog and digital displays including a speedometer, odometer, tachometer, turn signals, digital clock, fuel and temperature indicator.
  • Comfort: Ergonomics are among the best with the low center of gravity and excellent balance. Reach to the controls are perfect and the DOT approved windshield has just the right height. With the comfortable upright position, the Citycom S 300i feels just custom made.
  • Storage: Under seat storage is spacious with plenty of room for a full face helmet with a lot of room around it to stuff other things. There’s also a front glove box great to store sunglasses, garage openers and other small items.
  • Built-in Power Outlet: A power outlet is also built-in in the front glove box to powered your smart phone and other electronic devices.
