One platform, thirty years of obsession

Kent He 390 exists because the Kawasaki 500cc two-stroke triple deserves a specialist and never had one. The H1 Mach III and its siblings — the H2 750 and the S-series — were the fastest, most terrifying motorcycles of their era, brilliant and fragile in equal measure. Kent He bought his first tired H1 as a young mechanic, discovered that no shop in North America would touch the platform honestly, and decided to become that shop. Decades later, the name on the door is the model on the bench.

What we rebuild

The shop restores the 1969–1975 triple platform exclusively: H1, H1R, H1F, H2, and the S1/S2 series. Every rebuild is a complete frame-off restoration — engine cases split and measured, crank rebuilt with new rods and seals, cases vapor-honed, frames straightened and aligned, tanks chemically sealed, and period-correct finishes sourced or recreated where suppliers have long vanished. Each build ships with a documented photo record and a specification binder, because a restoration without documentation is just a nice-looking rumour.

How the work is scheduled

Restorations are booked into a queue with a realistic cycle measured in months, and clients receive progress updates at every stage gate — teardown findings, machining, assembly, tuning. Some customers bring one bike and keep it; others return with the next project, which is the retention story we're proudest of.

• Complete frame-off rebuilds of the 1969–1975 triple platform
• Documented photo record and specification binder with every build
• Stage-gate progress updates from teardown to final tuning

Kent He 390 serves collectors, racers, and riders who understand that a Kawasaki triple is only correct when it's rebuilt correctly. If your Mach III has been waiting decades for someone who cares, you've found the bench.
