Build by Dirt ‘N Iron 

Back in 2016 I bought a 2012 Suzuki RM-Z450 from Sebastien Tortelli. We met in front of Starbucks, I gave it a short test ride in the parking lot, and we sealed the deal. This used to be Yoshimura Suzuki’s bike before Sebastien got it. Four years later, and more than 120 hours on the clock, the bike felt a little tired. I thought she deserved a second chance and decided to take the bike down to the frame and do a complete overhaul. The plan was simple… make her better than new! 

I had a lot of fun building this bike, and I went through absolutely everything: engine, suspension, bearings, wheels, drivetrain, brakes, seat, plastics, etc. I also documented all the work in the rebuild videos on my Youtube channel. The modifications we did to this bike amplify all the good points about the RM-Z, including user-friendly power, good suspension, stock reliability, and of course great turning. With a little bit of love and a lot of elbow grease, this older MX bike got a new life and is now definitely better than new. Here's the products I used:
