The weights of the KTM Duke 250 and 390 from 2017 are relatively similar due to their shared platform and design similarities. Here are a few reasons why their weights are close:
Chassis and Frame: The Duke 250 and 390 from 2017 share a common chassis and frame design. This similarity in the frame structure helps keep the overall weight of the motorcycles similar. The chassis is often designed to accommodate the larger engine of the Duke 390 while maintaining a compact and lightweight structure.
Component Sharing: To optimize production costs, manufacturers often use common components across different models within the same lineup. This approach can help keep the weight similar between two models. In the case of the Duke 250 and 390, they may share certain components, such as the frame, suspension, braking system, or bodywork, which contribute to the overall weight similarity.
Engine Differences: While the Duke 250 and 390 have different engine displacements, the engines themselves may have certain similarities in terms of design and materials used. This can result in minimal differences in weight between the engines, contributing to the overall similarity in weight between the two models.
It's worth noting that the actual weight of a motorcycle can vary depending on factors such as optional features, fuel capacity, and manufacturing tolerances. For precise weight specifications, it's advisable to refer to the official specifications provided by the manufacturer.
