Harley-Davidson and Metric Customs

North County Hyper Sports has decades of experience in delivering first-class design and fabrication when it is time to talk custom motorcycles. Glenn has won his share of show and magazine attention with both metric cruisers and of course the Harley-Davidsons that we know and love. Bring what you have now for further modification, or start with a fresh build, but know that North County Hyper Sports can provide all the usual custom bike work like chrome, polished aluminum and custom paint from mild to wild.


A native of San Diego, Glenn grew up in Chula Vista, where he was his high school's motocross champion. His first job was in a Suzuki motorcycle dealer, Hurst Supply, owned by the family of world champion Kevin Schwantz. That led to him traveling with the Kenny Roberts/Mert Lawill racing team — an experience that taught him a lot.

In 1989, Glenn started North County Hyper Sports, a dyno tuning center, where the Hyper Sports Racing Team was formed. The group had years of success at Willow Springs; he built the motor and set up the front end of a GSXR1300 that set six world records over six days — one of the best weeks in his motorcycle life. He also had a chopper appear on Thunder Garage, winning Best of Show at Hollister.

Along with motorcycles, golf became an obsession for Glenn, who usually plays 2-3 times a week. Wanting to enjoy both passions together, he designed the Golf Caddy — so he can get to the links stress-free, without having to deal with the hassles of traffic, saving time and gas. It took nine months and four prototypes to perfect the Golf Caddy for his Harley-Davidson; now it slips through the wind as if it's not even there.
