Chassis

Frame overview

Although each of the three models has a different character, they all share a common frame that delivers features to satisfy our customers across the globe: nimble handling, reassuring stability and a riding position designed for comfort and easy handling.

As well as having all the essential functions required for anyone to experience the unique thrill of riding a bike, be they a beginner or a veteran, the size and dimensions of the shared frame and its stability and riding position mean that as well as being ideal for casual everyday use, it is also amply suited to touring and FUN riding. This is possible thanks to a lower centre of gravity fuel tank and other ways in which the frame lends itself to bringing the machines' mass together, making them extremely easy to handle when maneuvering.

Supporting a lightweight, compact engine that offers tangible torque at low rpm, an exhaustive CAE analysis led to a frame of optimum rigidity and toughness featuring a diamond-shape structure of round steel pipes offering both rigidity and flexibility. The machines are easy to handle because their shared frame is uniformly pliable and also stable, regardless of load.

Although lightweight, the frame ensures ample rigidity for FUN riding. At the same time, the toughness of the steel pipes enables the framework to respond smoothly and flexibly to constantly changing road surfaces and to achieve excellent riding stability and turning performance. This provides a high-quality ride that transmits a comfortable level of vibration to the rider.

Frame details

The frame, which supports a lightweight, compact engine that has distinctive forward-tilting cylinders and delivers tangible torque at low rpm, has a diamond structure made up of round steel pipes to achieve maximum efficiency with the smallest number of component parts.

Instead of a conventional structure with four main pipes that pass through, above, and below the head pipe, the frame employs a truss structure (A in the figure below) between the head pipe and the pivot, with the main pipe as the backbone and only one connecting cross pipe. Points of weakness (bends, etc.) have been eliminated and rigidity balance achieved through the diameter of the main pipe and the thickness of its metal.

In order to successfully realize three models of different character but also deliver stable, straightforward handling while making room for a large-capacity utility box and other features, the main frame is designed to sit lower than a conventional motorcycle. Also, even though optimization of the engine mount position means no cross pipe from the down tubes, the frame as a whole still achieves optimum rigidity (B below).

Furthermore, in order to ensure both excellent ground reach and the rear-mounting of a fuel tank with sufficient capacity, the seat rail has been fashioned from lightweight high-tensile steel pipe which passes through at a low position and narrow pitch (C below).
