Left handle brake lever

[Bar None]

this is all i have. pretty sure you can get a clear shot of it if you pull the cover off the rh side of the bike. its 1 screw and 1 rivet and a bit of finagling.
hope this is somewhat helpful.

Thanks. I will try that.

I will try that.

Did you hear back from Ox Brake? Does that product seem compatible with the Trail? If not, is it close? Are they working on making something that's compatible?

EDIT: I'm really hoping for good news here, part diagrams make the Trail rear brake look MIGHTY similar to the Honda pictured on the Ox Brake website.

Nevermind, I wasn't paying enough attention when I pulled up the part diagram. The reservoir isn't integral to the master cylinder, so the Ox Brake is not compatible as it is currently designed.
