Master Cylinder Compatibility

[exbellicus]

Would a front master cylinder from an 81 GS750 (59600-45130) be okay to replace my 80 GS450's(59600-45080)?

Thanks in advance

I don't think you can mix single caliper with dual.

Ok thanks Chef.

How about handlebar size, 7/8" or 1"?

GS handlebars are 7/8". 1" is a Harley size, plus some of the modern big metric crusiers have adopted it as well.

Single disc brake master cylinders are 14 mm, whereas dual disc GS masters are 5/8" which is larger. You can use a 5/8" master on a single disc bike but the hand pressure required to use the brake will increase. One side benefit of the large bore master is the lever will have a firm feel with less sponginess than a 14 mm master.
