①The engine soft connection is a reinforced spring soft connection, which has the following advantages:

a. Strong vibration absorbing ability and less vibration.

b. Long service life

c. Maintenance and replacement are more convenient

②The starting rod is made of 45 steel, which is durable and not easily deformed.

③Gear connection mechanism:

a. Double ball head dustproof design, flexible gearshift, no abnormal noise.

b. The connecting rod can be adjusted

c. Connect with the frame rubber sleeve to reduce noise

④The gear spline modulation treatment: durable, not easy to wear and deform

⑤The front and rear bracket beams of the engine are optimized and upgraded by cold plate stamping forming, which increases the strength and aesthetics of the bracket.

⑥Other companys engine connection method

a. Rubber connection, rectangular tube bracket

b. Welded directly to the position of the keel without position optimization.

⑦Enlarged double-layer pedals, comfortable, durable and non-slip, pedal glue can be replaced

⑧Molded water pipe to ensure smooth flow of water without obstruction

⑨The radiator is designed in parallel with the front beam of the keel, which avoids the interference between the radiator and the front fender and exhaust pipe

⑩The water temperature temperature control switch is added to realize the double insurance of automatic water temperature control and manual switch control.

The front section and the rear section of the exhaust pipe are connected by graphite gaskets with metal wire mesh, which completely solves the old problems of traditional graphite gaskets that are easy to leak and have been damaged.

Through the following optimizations, the problems of cylinder head bolt fracture and muffler air leakage have been completely solved. The muffler is divided into three sections, which are connected by double ball heads, and the cylinder head bare bolts are locked with self-locking nuts, which changes the vibration frequency of the exhaust pipe. The old problem of broken and easy loosening of the bare bolt of the cylinder head is solved.
