BIKE: 1975 Moto Guzzi 850 T3

The Bay Area has a great riding scene and culture and Grey Dog Moto is part of why it’s so good on the left coast.  Alameda, CA is an island sandwiched between San Francisco and Oakland and Patrick Bell’s Grey Dog takes up just 150 sq. ft. of prime bike building real estate. With a love for speed and a laid back Weimaraner named Berlin as his CEO, Bell has turned his passion into his profession. In episode one of season four Bell chopped a cherry ’75 Guzzi for an over-sized client and took a few risks along the way.

“This bike was built for a very tall customer who now fits nicely onto this custom Moto Guzzi cafe racer. No easy task for such a tall order (pun intended). Lots of custom bits to ensure substantial braking and suspension needs. A real powerhouse to ride and smooth as silk even at 100 mph. This Guzzi is not only insane fun to ride it’s a reliable daily driver.”
