This frame was developed through extensive testing by team rider Yuma Oshimo and the DURCUS ONE development team.
Built to withstand demanding riding conditions, the frame is constructed from high-strength 4130 chromoly steel.
The frame features a MID bottom bracket that directly accepts sealed bearings, along with an integrated head tube design that also houses sealed bearings. This combination improves both durability and ease of maintenance.
Based on rider feedback, every detail was carefully refined, including tube shapes, wall thickness, angles, and weld placement.
The short rear end, adjustable from 12.9" to 13.38", makes front lifts easier and provides responsive handling. The low 11.5" BB height enhances stability and control.
The frame is compatible with tires up to 2.4" wide and features heat-treated dropouts for additional strength during high-level riding.
Every aspect of the design has been carefully considered to satisfy even the most demanding riders. Whether riding street, park, or dirt, this frame is built for high-performance BMX riding.
Available in two top tube lengths to suit different rider heights and riding styles.
As a special bonus, each frame comes with one MOTO-BUNKA sticker pack and one large MOTO-BUNKA sticker!

[DURCUS ONE] DURCUS ONE was founded in 2004 by riders who had long been riding the streets of Tokyo, with the goal of creating what they believed to be the ideal bike for street riding.
The brand's first product was the H-STREET, a model that expanded BMX beyond tricks and helped introduce the concept of cruising by bicycle to the Japanese scene.
Today, DURCUS ONE continues to develop and release products based on the feedback and experience of riders who remain active in the streets.
