At the 2025 Mooneyes Yokohama Hot Rod Custom Show, one bike stood above the rest—not just for its finish, but for its presence. Takuya Okubo of Vidamotorcycle took first place in the S&S Vintage Tour–Mooneyes Japan showcase with a machine powered by the S&S SH-Series engine, delivering a bold interpretation of Shovelhead-era performance and style.
The SH-Series platform represents one of the most rebellious eras in American V-twin history. Known for its raw attitude and unmistakable mechanical character, the Shovelhead has long been associated with ‘70s chopper culture and unapologetic performance. Okubo didn’t just replicate that energy—he elevated it.
The centerpiece of the build is the SH-Series engine itself, transformed into rolling artwork through extensive hand engraving. According to S&S marketing chief Howard Kelly, the engraving alone took four continuous days to complete—every line carefully executed by a master craftsman. The result is a motor that blurs the line between engineering and art.
Visually, the bike balances aggression with restraint. A subtle silver paint scheme shifts tone under changing light, rewarding close inspection rather than quick social media glances. The finish work reflects a uniquely Japanese philosophy: detail over flash, craftsmanship over spectacle.
But this build isn’t just about aesthetics. It’s a statement about the relevance of vintage platforms in modern custom culture. For years, S&S acknowledged that engines like the SH-Series weren’t given the spotlight they deserved. The Vintage Tour program—placing engines in the hands of elite builders—has changed that narrative entirely.

Okubo’s winning machine proves that the SH platform remains as powerful creatively as it ever was. It’s not a relic—it’s a foundation for expression.
At Mooneyes, the reaction was immediate. Crowds stopped as the three S&S-powered bikes were displayed together, but Okubo’s SH build anchored the trio with unmistakable presence. It’s louder, more aggressive, and unapologetically bold—yet executed with the precision that defines Japanese craftsmanship.

With plans for select builds to appear at events like Born-Free, this cross-cultural exchange continues to reinforce the global impact of American V-twin heritage.
In Yokohama, the SH-Series didn’t just win a competition—it reminded everyone why the Shovelhead era still matters. HB
