Suzuki gt125

[Alf]

Does anyone know the bearing size for headstock, judging by the cup the top and bottom are different.
I would really appreciate any help as I've inherited several boxes which hopefully will eventually become a bike,
Thanks

Robinson’s Foundry are a Suzuki dealer who may be able to help you with parts/information on older Suzuki’s

Or try Crooks Suzuki.

Crooks had the parts for a 1976 TS 250 I was fixing.

Don't pull out either your wallet or your bearing drift or clamps until you've checked, but I think this is the (modern tapered roller replacement) set for the GT125:

This (tapered roller bearing) product set is called TOURMAX JMT 7369424

Verify this info first before trying to fit your bearings! I take no responsibility.

The dimensions given on that page are:

Outer Diameter : 45 mm
Inner Diameter : 25 mm
Height : 14.5 mm
Outer Diameter : 48 mm
Inner Diameter : 27 mm
