CHASSIS DIMENSION “FRAME WORKS”

The basis of A16 is the steel tubular frame, twin-spar double cradle, which is ideal for high-speed stability.
Large diameter steering shaft and swingarm pivot shaft with a wide dimension, which is fitted to the frame, are the standard size used in modern motorcycles.
Steering head pipe and swinging-arm pivot bracket are so important parts of our frame that we machined them one by one very carefully by machining center.
Its structure is so strong, and we spend a lot of time, energy and money on machining these excellent parts.
Steel tubular pipe is designed not at former standardized setting, but to be much stronger sturdy, engineered to provide high rigidity against the twist under the heavy load.
Even though it holds the big KZ's 1000cc engine, the chassis is compact and the low center of gravity enables you to enjoy high stability.
This frame is carefully hand-made by our skilled craftsmen, one by one, specially for you, limited to a small number.
