Review SUZUKI Oem Engine Motor Cylinder Top End fits RMZ450 2017

The Suzuki RMZ450, model year 2017, is a high-performance motocross motorcycle renowned for its power and agility. At the heart of this machine lies the B4509 cylinder top end for its 449cc, four-stroke, liquid-cooled engine. This crucial component ensures the seamless transfer of power from the engine to the drivetrain, significantly contributing to the bike's excellent on-track performance.

The cylinder top end is a meticulously engineered assembly consisting of a piston, cylinder head, and associated components. The piston is a forged aluminum alloy piece, designed for durability and efficiency. It features a compact, symmetrical design, which reduces weight and improves power output. The piston crown is optimized for superior combustion efficiency and features a 260-degree transfer port design for efficient fuel delivery.

The cylinder head is a sophisticated piece of engineering, with an oversquare bore and stroke of 96.0mm x 62.1mm. It features large intake and exhaust ports, which ensure optimal gas flow for maximum power output. The head also houses four valves, which are operated by a DOHC (double overhead camshaft) system. The valves are actuated by finger followers, which provide a direct intake-to-cylinder connection, ensuring precise valve control and improved engine response.

The cylinder head also features Suzuki's EFI (Electronic Fuel Injection) system, which ensures precise fuel delivery for optimal combustion efficiency. This system uses a 38mm throttle body and a 12-hole injector, which provides a fine fuel mist for efficient combustion. The EFI system also features a secondary air system, which injects fresh air into the cylinder during the exhaust stroke, reducing harmful emissions and improving engine efficiency.

The cylinder top end also includes various other components, such as the camshafts, cam followers, and valve springs, all of which are designed for high-performance operation and durability. The cylinder head is further enhanced by Suzuki's advanced cooling system, which includes a liquid-cooling jacket and an oil cooling system, ensuring consistent engine temperature and optimal performance under various conditions.

In conclusion, the Suzuki RMZ450's B4509 cylinder top end is a high-performance, meticulously engineered component that significantly contributes to the bike's power and agility. Its forged aluminum piston, sophisticated cylinder head design, and advanced EFI system ensure optimal combustion efficiency, power output, and durability. This component is a testament to Suzuki's commitment to delivering high-performance motocross motorcycles that set the standard for the industry.

The Suzuki RMZ450 is a popular motocross bike known for its power and agility. The 2017 model year uses the B4509 engine cylinder top end in its motor. Here are some pros and cons of buying this specific part.

1. OEM Part: This is an original equipment manufacturer (OEM) part, which means it is made by Suzuki and is designed to fit and function optimally in the RMZ450 motor.

3. Performance: Replacing a worn-out top end cylinder with a new one can improve engine performance, as it ensures proper compression and ignition.

4. Availability: This is a commonly used part in the Suzuki RMZ450 motor, so it is relatively easy to find and purchase.

1. Cost: OEM parts can be more expensive than aftermarket alternatives because they are made by the manufacturer and come with a warranty.

2. Installation: Installing the new top end cylinder can be a complex process and may require specialized tools or professional help.

3. Disassembly: To replace the top end cylinder, the engine must be disassembled, which can be time-consuming and labor-intensive.

The Suzuki RMZ450 B4509 engine cylinder top end is a high-quality OEM part that can improve engine performance and reliability.
