Kaihong Motorcycle Carbon Timing Belt is developed for motorcycle drive systems where low weight, stable power transmission, and reduced maintenance are important. The belt uses a composite structure combining HNBR rubber, high-strength carbon fiber tensile cords, and a wear-resistant nylon tooth surface.
Compared with conventional chain drives, the belt operates without lubrication and avoids metal-to-metal contact, helping reduce running noise, oil contamination, and routine maintenance. Its low elongation and stable tooth engagement also support consistent power transmission during acceleration and long-distance riding.
The Motorcycle Carbon Timing Belt body uses HNBR rubber for resistance to heat, oil, aging, and repeated mechanical loading. This makes it suitable for motorcycle environments exposed to engine heat, vibration, and road contaminants.
High-strength carbon fiber forms the main tensile member. Its low elongation helps maintain belt tension and reduces the risk of tooth skipping during rapid acceleration or changes in load.
The tooth surface uses a wear-resistant nylon fabric to reduce friction and protect the molded teeth during repeated pulley engagement. The material also contributes to smoother and quieter operation.
A nylon-reinforced back structure improves transverse strength and protects the belt body against external wear. The construction is suitable for motorcycle drive layouts involving multiple pulleys.

Carbon fiber reinforcement provides high tensile strength with very low elongation. The belt can therefore maintain more stable dimensions during long-term operation.
The synchronous tooth engagement avoids the metal-on-metal contact associated with conventional chains. This helps reduce drivetrain noise, particularly on electric motorcycles and urban commuter bikes.
The belt does not require chain oil. This eliminates regular lubrication work and reduces the possibility of oil splashing onto wheels, frames, or rider clothing.
The HNBR compound is designed to maintain mechanical properties under elevated temperatures and exposure to common motorcycle contaminants such as oil and fuel.
The optimized 11 mm tooth profile is designed for reliable pulley engagement. Combined with the carbon tensile cord, it helps maintain synchronized transmission and reduce tooth jumping.
The composite structure reduces the mass of the transmission component compared with conventional metal chain systems. Lower rotating mass can contribute to responsive drivetrain behavior.
For small-displacement motorcycles and scooters used in frequent stop-and-go traffic, the belt provides a clean and low-maintenance alternative to conventional chains.
The supplied application examples include QINGQI SUZUKI UY125, Haojue UHR, Honda NS125RX, and Yamaha Cygnus Ray ZR (JOG i).
Mid-displacement cruiser and bobber models can benefit from the quiet operation and clean appearance of belt transmission. Example models include Benda Jinjila 300, Longjia V-Bob, VOGE CU525, SWM GV650, QJMotor Flash 300/350, and Harley-Davidson Street 750.
Long-distance motorcycles require stable transmission performance across different weather and road conditions. The supplied application examples include Honda NC750X ADV and BMW R1250GS, where reduced lubrication requirements can simplify long-distance maintenance.
For larger-displacement motorcycles, the high tensile strength and low elongation of carbon fiber reinforcement support applications involving rapid acceleration and higher drivetrain loads.
Electric motorcycles benefit particularly from low transmission noise. The belt's lubrication-free construction also keeps the drivetrain clean and reduces routine maintenance requirements.
Cafe racers, bobbers, retro motorcycles, and other custom builds can use belt transmission where a clean appearance and simplified maintenance are priorities.
The reinforced tooth structure provides high shear resistance, helping reduce tooth damage and skipping under demanding operating conditions.
The carbon cord combines high tensile strength with very low elongation, supporting stable transmission over extended service periods.
The specialized tooth fabric provides low-friction characteristics without requiring external lubrication.
The Motorcycle Carbon Timing Belt body incorporates an antistatic design for applications where control of static accumulation is required.
Flame-retardant characteristics are available for applications where additional safety requirements need to be considered.
The driving and driven pulleys should remain properly aligned. Misalignment can cause uneven tooth wear and edge damage.
Belt tension should follow the motorcycle manufacturer's specification. Excessive tension increases bearing loads, while insufficient tension may cause vibration or tooth skipping.
During routine service, check for tooth wear, cracking, fabric damage, or abnormal deformation. Replace the belt if significant damage is found.
Although lubrication is unnecessary, the pulley and belt should be kept free from excessive oil, mud, stones, and other contaminants.
After installation, rotate the pulley manually to confirm correct tooth engagement before operating the motorcycle at normal speed.
Kaihong can produce different belt lengths, tooth counts, and widths according to customer drawings or original belt samples.
OEM branding and logo printing are available for motorcycle manufacturers, distributors, and aftermarket suppliers.
