WAVE 125 Cylinder Kit 57mm

WAVE 125 Cylinder Kit 57mm

57mm upgrade with stock-fit simplicity—precise alignment, reliable sealing.

The WAVE 125 Cylinder Kit upgrades Honda WAVE 125 scooters to a 57mm bore. Components are precisely machined for smooth piston travel and consistent sealing, while stock-fit interfaces keep assembly straightforward.

🔹 Aluminum-Alloy Cylinder Body — Efficient heat conduction and structural rigidity
🔹 57mm Bore-Up Specification — Increased displacement versus stock (year/market dependent)
🔹 Precision Machining — Stable ring sealing and smooth piston motion
🔹 OEM-Fit Interfaces — Stock-layout mounting for accurate, hassle-free assembly
🔹 Complete Kit — Includes cylinder, piston, rings, pin, circlips, gasket

Product Specifications
Bore Size: 57mm
Material: Aluminum-alloy cylinder
Fitment: HONDA WAVE 125 models (year/market dependent)
Focus: Bore-up upgrade, consistent sealing, straightforward install
Package Includes: Cylinder, piston, piston rings, piston pin, circlips, cylinder gasket

Installation Notes
• Confirm original bore and model year before installation.
• For bore-up builds, verify cylinder head and gasket compatibility; recheck fueling (carb jetting / FI calibration).
• Follow standard break-in for new rings; re-torque fasteners after initial heat cycles.

WAVE 125 Ceramic Cylinder Kit 57mm

WAVE 125 Ceramic Cylinder Kit 57mm

Ceramic-coated exterior finish—heat-resistant durability with stock-fit simplicity.

The WAVE 125 Ceramic Cylinder Kit upgrades Honda WAVE 125 to a 57mm bore and features a ceramic-coated exterior surface for a heat-resistant, corrosion-resistant finish. The bore itself is precision-machined to maintain smooth piston travel and consistent sealing, while stock-fit interfaces keep assembly straightforward.

🔹 Ceramic-Coated Exterior — Heat-resistant, corrosion-resistant finish on the outer surface
🔹 Aluminum-Alloy Cylinder Body — Lightweight structure with stable heat conduction
🔹 Precision Machining — Consistent ring sealing and smooth piston motion at the bore
🔹 OEM-Fit Interfaces — Stock-layout mounting for accurate, hassle-free assembly
🔹 Complete Kit — Includes cylinder, piston, rings, pin, circlips, gasket

Product Specifications
Bore Size: 57mm
Material: Aluminum-alloy cylinder with ceramic-coated exterior 
Fitment: HONDA WAVE 125 models (year/market dependent)
Focus: Heat-resistant exterior finish, consistent sealing via precision machining, straightforward install
Package Includes: Cylinder, piston, piston rings, piston pin, circlips, cylinder gasket

Installation Notes

GY6 125 Tilt-Blade Cylinder Kit

GY6 125 Tilt-Blade Cylinder Kit

Durable Alloy Body with Tilt-Blade Fins for Directed Airflow

The GY6 125 Tilt-Blade Cylinder Kit uses a high-strength aluminum-alloy cylinder with angled cooling fins designed to pair with stock shrouds, helping guide airflow across the cylinder. Offered in 58.5 / 61 / 63mm bore sizes, it suits both standard rebuilds and displacement upgrades while keeping installation straightforward and sealing consistent.

🔹 Aluminum-Alloy Cylinder Body – Rigid structure with good heat conduction
🔹 Tilt-Blade Fin Layout – Angled fins align with OEM shrouds for directed cooling airflow
🔹 Precision Machining – Consistent ring sealing and smooth piston travel
🔹 OEM-Fit Interfaces – Stock-layout mounting for accurate, hassle-free assembly
🔹 Multiple Bore Options – 58.5 / 61 / 63mm to match your build goals

Product Specifications

Bore Sizes: 58.5mm / 61mm / 63mm
Material: Aluminum-alloy cylinder
Fitment: Scooters equipped with the GY6 125 engine (year/market dependent)
Focus: Consistent sealing, airflow alignment, straightforward install
Package Includes: Cylinder, piston, piston rings, piston pin, circlips, cylinder gasket

Installation Notes
• Confirm bore size and vehicle year before installation.
• For bore-up builds, verify cylinder head and gasket compatibility; recheck fueling (carb jetting / FI calibration).
• After assembly, ensure shroud/air-duct alignment with the tilt-blade fins.
