In need of a sight glass for my brake reservoir. Options?

[dpkshafer]

I’ve owned scooters and motorcycles and never had this happen. The sight glass fell out of the brake fluid reservoir on my 2019 C400X. Might be due to the extreme weather in Florida but my front brakes were inoperable. I’ve got a temporary fix and ordered a new from BMW. But there are none available in the US and only 5 worldwide. They’re all in Germany and mine doesn’t seem to be coming in a hurry. Anybody aware of a used scooter parts dealer? Or maybe the break fluid reservoir and sight glass are common to other model scooters? Thanks

1) Welcome to the forum.

2) Do you still have the glass itself (in case anyone has a suggestion for gluing it back in, or something like that)?

3) According to pages at CalMoto.com, https://bmwparts.crosscountrycycle.net, etc., the front brake assembly fits our C 400 GTs and Xs, but that's it:

Thanks. The glass is somewhere down the highway. It’s a 2019 model. It’s the reservoir for the front brakes that lost the sight glass. Though the reservoirs look like they have the identical sight glass. I tried buying an 18mm size off eBay that was supposed to fit but it does not. I know lots of different scooter brands and models use common components so I was hoping maybe someone could point me somewhere other than BMW. Part has been on order for over a month now and hasn’t hit the US shore. No ETA for that first step.

My actual part finally arrived from Germany and got delivered today. I feel whole again riding my scooter around Key West care free. Thanks for all the input.
