The Road

Timeline.

  1. 2008

    Turned a wrench at 12.

    First stripped-down 100cc in the family garage. Oil on hands, fascinated.

  2. 2012

    First race build.

    Prepped a Pulsar 220 for grassroots drags. Outran stock 300s. Hooked.

  3. 2015

    Apprenticed with factory tuners.

    Two years with a WSBK-feeder team. Learned maps, metallurgy, madness.

  4. 2018

    Welding school + fabrication era.

    TIG certification. Started fabricating subframes, sliders, race exhausts.

  5. 2020

    Opened the bay.

    First 6T4 CUSTOMS bay opened in Hyderabad. Dyno followed six months later.

  6. Now

    1,200+ bikes. Still counting.

    Full-service garage. Every build signed off by hand. No shortcuts.

Philosophy

Every bike leaves sharper
than it came in.

We don't do appointments-for-appointments. If the dyno isn't happy, the bike doesn't leave. That's the deal.
