What Yamaha Hub is this? (now with image!)
« on: October 02, 2012, 05:57:48 pm »
Trying to identify this Yamaha hub for a friend.  Here's the sketch of what he's looking for:



He thinks it's from a YZ250-490 from around 1980-82.  No code cast into it, and a single rib around the brake side.

Anyone know what it is?  He's looking to buy one.

Thanks, Tony

Any hints on brake diameter?

81 models had big drums compared to 80 and 82+ YZs.

The large spoke diameter suggests a later model than the 81 4V4 hub.

Looks like a 4V4 to me. The H models are the only ones I am aware of with the single rib. Both the G & J had two ribs.
