2nd Prototype of "Yabusame" frame for the Bike Polo, made in Japan
The geometry of 2nd prototype of YABUSAME frame is adjusted basing a lot of feedbacks from a long-term test of the first one.

And, we raised the rigidity of its rear triangle further, and aimed at the goodness of direct acceleration and the strength that kept being used tough.

Three big holes in the seat tube enable lightening a little with the rigidity secured with a thick pipe.

Crow (THBP/Raijing) tests this frame.

We think that the way until putting on the market is not too far.

The Yabusame project is based on the colaboration between Okayasu Factory, TUBAGRA, and JBP.
