( Manufacturer Part Number: 3R0-21611-00-00 ), ( Part Type: Frame )
The 3R0-21611-00-00 frame chassis is a vintage piece from Yamaha's YZ 50 model, produced in 1980. This frame chassis is a testament to Yamaha's engineering prowess in the 80s, offering a balance of durability, lightweight design, and agility.
The chassis is made primarily of high-tensile steel, ensuring strength and rigidity, while keeping the overall weight of the bike relatively low. This contributes to the bike's nimbleness and maneuverability, making it ideal for off-road racing or recreational use.
The frame design features a double-cradle layout, a common design choice for motocross bikes of the time. This design provides excellent torsional rigidity, ensuring that the bike stays stable and responds predictably to the rider's inputs. The chassis also features a tapered aluminum swingarm, which not only reduces the unsprung weight of the bike but also increases traction and stability during high-speed cornering.
The fit and finish of the frame chassis are exemplary, with smooth welds and clean lines. The powder coat paint job provides excellent protection against corrosion, preserving the chassis's appearance and performance over time.
In summary, the 3R0-21611-00-00 frame chassis is a valuable piece of motocross history, offering a blend of strength, lightweight design, and agility. Whether you're restoring an original 1980 YZ 50 or building a custom off-road bike, this frame chassis is a solid foundation for your project.
