The 4-stroke engine, fuel injection system with provides a unique power character, with outstanding torque and throttle response, combined with strong high-rpm pulling power.

SYM’s 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 the engine.

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 etc., which can be the best candidate matching the requirements of the engine cylinder. General conventional electroplating techniques cannot disperse SiC ceramic particles on the cylinder wall due to the insulation and high weight. As a result, SYM has 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.

The Rear Dual Shock Supensions System features sport-oriented geometry to achieve light and nimble handling, aided by the minimalist 295.4 pound net weight and refined ergonomics.

Lightweight cast aluminum wheels are fitted with a 100/90-14 front tire and 110/80-14 rear tire for excellent traction and handling feel. The Jet 14 200i also features performance tires that combine modern construction with retro design.

With wide handlebar, white stitched two-level sporty seat, and perfectly placed foot controls provide a comfortably riding position ideal for urban traffic or hustling down a twisty road. With a seat height of 30", average riders are able to have both feet planted for a more secure ride.

The Fiddle 4 lockable under seat storage is spacious with plenty of room for a half helmet with a lot of room around it to stuff other things.
