Front Master Cylinder size

[JoeV11]

I found a master cylinder that may work on my race bike. It fits 2001-2004 Stone / Jackal and was wondering if anyone knows what the piston diameter is? Also that master fits 7/8" bars right? Thanks, Joe

Anyone? Anyone? Bueller?

For a V11 Sport? The stock size is 16mm. A 15mm will work fine. The Stone one is, I think, a 13mm.

I'm pretty sure Bueller is long gone from v11lemans.com

 

As Greg mentioned, a master cylinder from a single disk bike is going to have a smaller piston than a master cylinder from a dual disk bike.

Thanks, I'm actually looking for a master cylinder for a '76 Yamaha RD400 I'm making into a vintage racer:

 

 

 

It has a single disk and a 5/8 master now but it hits the clipon. I'm hoping to find a slimmer one about the same size maybe slightly smaller.

 

Thanks

Joe
