Cylinder Blocks & Motorcycle Applications
For cylinder-block enquiries, review the Yamaha LC135 Ceramic Cylinder Block and the Yamaha NMAX155 / Aerox155 Ceramic Cylinder Block. Confirm the exact motorcycle model and engine version before quotation.
OEM/ODM Customization
Ruizheng Racing supports OEM/ODM and custom motorcycle cylinder component projects based on confirmed specifications, drawings or samples. Customization requirements may include component dimensions, compatible engine configurations, branding and packaging, subject to technical review. Buyers can provide the engine model, quantity, destination country and technical reference for quotation.
Cylinder Specifications & Fitment Confirmation
Before quotation, confirm the motorcycle model, engine code, cylinder bore size, piston pin diameter and applicable engine version where relevant. Additional dimensions and compatibility requirements should be checked against the drawing, sample or approved technical specifications. Specifications must not be assumed interchangeable across different engine generations.
