Garage Build

Building a green beast named Roxy

The Kawasaki KX450 got a bad rap in 2025 with Jorge Prado, but as I was leaving Loretta Lynn’s last year, I picked up a phone call from Jamie Ellis from Twisted Development, mentioning he wanted to build a KX450 for me to test. That phone call last August put this build in motion that you see here! In stock form, the KX450 is a mellow, somewhat lethargic 450, but with a little work, it can be transformed into a healthy machine that is fast enough for most. With this Garage Build, we wanted to take it a step further and really dive into the engine to see what Jamie and crew could dish out. Could Twisted Development build me a KX450 that is so fast that it would be un-ridable? Would I even like the type of power that it builds? “Roxy” absolutely changed the way I thought about KX450s in general. Below is how she became the boss of the garage/shop.
