In October 2017 Justin was diagnosed with cancer growing along the nerve in his jaw. This required a radical surgery removing a large portion of his jaw bone and 17 rounds of radiation. To occupy his mind and hands, he found and purchased two 500s to work on when he was fighting to survive during his recovery. This led to a discussion with me about rebuilding 500s and a garage build project. After all, the two of us grew up racing together in Arizona and we’ve both since become firefighters. Cancer within the fire service is rampant due to the exposure to carcinogenic materials on the job, making this project something very personal to both of us.

 

When Justin got the bikes, they were pretty beat up. We had to tear them all the way down to the frame. After reviewing the needed parts and getting a list together, parts were ordered. We were ready to get down to business. The frames were repainted and the bikes were rebuilt from the frame up. This was a 3 to 4-month process to complete and really helped Justin to deal with his serious health issues. One of the bikes Justin plans to keep and ride as a reminder of the single most difficult thing he’s ever had to deal with. The other bike he wanted to auction off to charity and the folks at Road 2 Recovery were our non-profit of choice.

The bike is currently up for auction.
