Yabusame 2nd proto

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.

ということで国産初のバイク・ポロ専用フレーム「Yabusame」の2ndプロトです。JBPのJinken曰く「1stプロトからのフィードバックを踏まえてジオメトリを調整し、リア回りの剛性を上げて俊敏な加速を狙っています。かなり強くなりました。」とのこと。チェーンステイ付け根部分の処理なんかはMozuシリーズと同様の処理にみえますね。
踏んだときの反応が気になるところです。
