Factory-level Kawasaki KLX125 Supermoto Build

Custom-built to your needs with complete wheels, brakes, and even optional lights and suspension to convert a Kawasaki KLX125 into a street-legal assassin… and we’ve lowered the price to help more riders. However, for those who want the best, we still have hundreds of upgrades to fulfill the need to be on top of the podium!

Kawasaki KLX125 Build list:

  • Wheel Assembly: spoke or tubeless mag rims with tires, rotors, sprocket, titanium bolts and the strongest chain included.
  • Brakes: Brembo full front radial 4 piston brake system along with upgraded rear master and rotors.
  • Free carbon fiber bars are included — a $300 value!

Optional Additions (“We’ll Take It All Kit” option + $6,000)… see more details below:

  • Turn your supermoto into a true street-legal assassin with…
  • Suspension: tuned for each rider with coatings… send in your stock set -or- get a full bolt-on kit for $3000 more.
  • Lighting: 10,000 lumen light and all LED accessories.
  • Titanium hardware
  • One-off painted wheels
  • Billet monoblock calipers

Use the same products the pros win with!

The design is 100% up to the buyer’s desire (we will make recommendations of course). We then build to spec with engineers and guidance from the top pros in design, performance, and functionality.

From building just for the look (like what we did for the movie Oblivion with Tom Cruise) to winning multiple supercross championships, we’ve done it and love the level of energy it takes to do it again!

What’s Included with All Options Selected:

All products work in unison. From restomods to straight flexing on the block, this kit is dialed-in for each rider.

      • Complete brake caliper, brackets, masters, lines, and titanium bolts.
      • Complete Wheels Built by the best that will never need spoke or sprocket replacements. Lifetime warranty on the rear sprocket and spoke tension.
      • Free Carbon Fiber Handlebars — a $300 value!
      • Larger bladders, pistons, and shafts, along with easier adjustment ability and coatings.
      • Speedometer, all lights including 10,000 lumen headlight, and upgraded battery.
      • Suspension is $7000 so to save you money, we’ll set-up your stock suspension (send it in to us)… OR, we have complete forks & shock for an additional $3000.
      • Any color combos of your choice on all areas of the suspension.
      • Then… suspension is personally set up with Graeme Brough, including as many calls, videos, and questions as needed to reach your bike’s full potential.

How does this kit address the electrical system? KX450F doesn't have OEM battery so how does the kit provide for one? Also wonder if the stock stator produces enough energy to run all legally required electrical components. Rob Bonnett asked on October 14, 2025

Few options: upgraded stater and/or a battery system to lower the load on the stater since the battery can run the kit for 4 hours with no help from the stater.
