Sam's - 1974 Kawasaki Z1 Restomod

1974 Kawasaki Z1 Restomod - Finished

When it was released in 1972 the Kawasaki Z1 was the most powerfull 4-cylinder 4-stroke motorcycle ever sold. In it's first year it set the world FIM and AMA record for 24-hour endurance with an average speed of 109.64 mph. That same year a Yoshimura tuned Z1 set a one lap record of 160.288 mph while being piloted by Yvon Duhamel in Daytona.

To bring this beauty back to 'better than new' condition her owner reached out to the AMW team to perform a complete frame up restoration, with a few twists. First we powder coated the frame, swingarm, triple clamps and hubs.

Then we moved onto the suspension, adding new Öhlins shocks to the rear and rebuilt the front forks with progressive springs then adding fork gaiters. We then opted to add dual disc brakes after upgrading to a Magura HC1 master cylinder.1974 Kawasaki Z1 Restomod - Wheels and wiring

Both front and read wheels were changed to 18” using relaced Sun rims, wrapped in Avon Road Rider tires. Then the wiring was updated using a new wiring harness.
