An AHRMA North Atlantic MX Committee member and a vice president of the Potomac Vintage Riders, the largest vintage motorcycle club in the US, FYZ founder Ed Day’s roots go back to the glory days of dirt bikes and motocross - the early 1970s.

Hopping off an Elsinore and onto his first YZ, a 125 X, back in 1976, Ed has been a fanatic Yamaha enthusiast ever since. For Ed, following a highly praised 2003 frame-up restoration with the YZ Works of a 1976 YZ 175, featured in world famous VMX magazine, the stage was set for a return to racing after a 30 year hiatus. The restoration also marked the beginning of a collection of YZs and their restorations spanning the brand’s halcyon days of 1976 to 1981. Through these restorations, YZ parts were located and sources developed that were previously unknown to the vintage racing public. Product was tested, evaluated, and approved under racing conditions. Now it’s all gathered here - for your convenience.
