GSX1100s: the Katana

1982 GSX1100s Suzuki Katana, shaved down and beefed up where it matters.

This iconic muscle bike quickly turned into a labor of love for us here at ACP Customs.

Ground-up build with suspension upgrades, frame mods, engine mods, custom parts and much more!

All work was done in-house.


All original pieces prepared and coated:

  • Powdercoated frame, engine covers, top triple

Frame mods: These frames were notorious for twisting, so bracing is key to keep everything square

  • Triangular, capped bracing in the rear frame
  • Curved bracing in the rear frame
  • All unnecessary tabs removed
  • Nitro Racing rear-sets

Front End: Top-shelf products and one-off parts

  • ACP designed top triple, machined out of billet aluminum
    • Brushed finish with powdercoat
  • ACP designed bottom triple, machined out of billet aluminum and cored (removal of excess material) for weight reduction
  • Woodcraft clip-ons
  • Brembo levers and perch
  • Motion Pro throttle kit

Suspension: Only the best with this upgrade

  • Over Racing Project braced swing arm
  • Ohlins front forks (2006 GSXR 1000)
  • Ohlins reservoir rear suspension

Breaking: When you need to stop on a dime…

  • Brembo front rotors and caliper
  • Brembo rear rotor and caliper
  • Brembo master cylinders

Wheels: When the rubbers weigh more then the rims, you know the bike will fly down the street

  • Custom Dymag magnesium wheels with ceramic bearings
  • Michelin Pilot Power 3 tires

Body: It’s just not a Katana without the front fairing!

  • Unicorn Racing Carbon fiber headlight fairing and accent pieces
  • Carbon One carbon fiber front fender
  • Smoked windscreen

Engine & Driveline: Beefed up because…why not?

  • The massive motor came to us bored out to a 1200cc
  • Ward top end oil kit with ACP designed adapter
  • Earl’s oil cooler with braided lines
  • Yoshimura sprocket cover
  • Ohno Racing pulsar cover
  • Flat-side FCR39 Keihin carburetors
  • New drive line components with D.I.D chain and Dymag sprockets
