Zach's 1989 Evolution Sportster Chopper

1989 Evolution Sportster Chopper

Zach Boxx is the owner of Throttle Addiction and recently rebuilt his Sporty Chopper to showcase many of the cool parts they offer.

Zach: "When I was a junior in high school I decided I needed to build a chopper. The problem was, I had no idea what I was doing, I didn't come from motorcycle blood lines and I had zero experience with no connections. My school had a program that would allow students to create their own independent study.  First I had to pitch the idea to the principal. To my surprise he approved it, and I had one class period a day where I was free to use the schools auto shop to take a crack at my first build."

Zach: "As summer approached, the bike was still not complete.  Since I would lose my build space, I decided to approach a few local Indy shops.  One shop was under new ownership and decided to take me in. I spent most of that summer under the direction of a few grumpy mechanics completing my bike. That was all 12 years ago."

"Time has passed; it’s gone through many updates and changes.  Recently I made the biggest overhaul.  I stripped it down to the frame, front end, and motor to rebuild it with many of the cool parts we make, or carry at Throttle Addiction. Its now running Throttle Addiction sheet metal – Frisco Wassell tank and a Wassell Style ribbed fender – Throttle Addiction Rabbit ear handlebars, lighting off our shelves.  I built the exhaust using the Biltwell Inc builders set, and had it chrome plated by Metro Plating in Mesa AZ.  I also built the sissy bar and that chrome plated that was chromed there as well.  The paint was done by Zombie Shaun in Ohio and the frame is still rocking the original candy red metal flake powder coat from the bikes first build."

"This bike is not only the first motorcycle I built, it’s the first bike I ever owned.  Since then, many bikes have come and gone, but this one will stay with me until my last ride."
