Ken's Factory

02/07/2026

You might’ve seen our feature in a recent issue of Hot Bike, it’s a bike we put together for a client here at our headquarters in Nagoya, Japan.

Because he’s looking to make some space for another bike, an unusual opportunity arose: this bike is actually for sale.

DM for any inquiries. Thank you.

先日のHot Bike誌で特集記事をご覧になった方もいらっしゃるかもしれません。これは、Kensのお客様向けに製作したバイクです。
新たな車両製作の為置き場所確保する為にこの度販売となりました。

お問い合わせはDMまで。ありがとうございます。

This Knucklehead is the perfect representation of blending styles, genres, technologies and more into whatever blank two-wheeled canvas he’s working on. Ken Nagai is an expert at blurring lines and of course is obsessed with the details. We always look forward to seeing what Ken’s going to build next.
