Motorcycle Parts

Leveraging our aluminum processing technology, we manufacture the main body parts of motorcycles, from frames, swingarms, and wheels to other parts. We offer products that are lightweight with high performance.

Lightweighting technology
that revolutionized motorcycle performance

Narita Manufacturing's aluminum processing technology has contributed greatly to improve motorcycle performance.
Converting conventional steel parts to aluminum helps achieve significant weight reduction and drastic improvements of acceleration, fuel economy, and maneuverability.

Frame Structures

Combining lighter weight with higher rigidity in main and sub frames, enhancing the stability and controllability of the entire automobile.
Swingarms

By reducing weight around the rear suspension while ensuring durability, improved stability and responsiveness on the road.
Aluminum Tanks

By reducing weight near the center of gravity, the running performance and controllability will improve, delivering a light, stable ride.

Primary Product Categories

Primary body parts that underpin motorcycle performance

Frame Structures

The main frame structure is the heart of a motorcycle. Leveraging the properties of aluminum alloys to enable weight reduction and enhanced rigidity, we are able to deliver excellent running performance and safety. With our proprietary welding technology, we are capable of welding complex shapes.

Key Features:: Main frames | Sub frames | High-rigidity design | Lightweight structures | Seat rails | Tank rails

Swingarms

Swingarms are a critical part of the rear suspension system. This refined part that directly impacts riding stability and performance can be created by aluminum forging and extrusion technology, which ensures weight reduction and high durability,

Key Features:: Aluminum welding | Bending | Aluminum casting | Vehicle weight reduction

Aluminum Tanks

Converting fuel tanks to aluminum reduces overall vehicle weight and the weight near the center of gravity, improving maneuverability and acceleration/deceleration performance. For off-road use, aluminum tanks contribute to greater impact durability. These are high-quality products that also enhance premium feel and brand value.

Key Features:: Aluminum pressing | Vehicle weight reduction | Higher added value
