A master cylinder assembly includes a housing and a cover coupled to the housing, defining a reservoir adapted to contain fluid at a level. The cover includes an aperture. A sight glass is received within the aperture and adapted to indicate the fluid level. The sight glass has a top portion, bottom portion, and middle portion between the top and bottom portions. The top and bottom portions each have a perimeter sized to be received within the aperture and to seal the reservoir. The middle portion has a reduced perimeter. The sight glass is movable between a raised position where the bottom portion is received within the aperture, sealing the reservoir and a lowered position where the top portion is received within the aperture, sealing the reservoir. The middle portion allows fluid flow through the aperture when the sight glass is moved from the raised position to the lowered position.

What is claimed is: 1. A master cylinder assembly for a brake system of a motorcycle, the master cylinder assembly comprising: a housing; a cover coupled to the housing to define a reservoir adapted to contain a fluid at a level, the cover including an aperture; a sight glass received within the aperture and adapted to indicate the level of the fluid within the reservoir, the sight glass having a top portion, a bottom portion, and a middle portion between the top and bottom portions, the top and bottom portions each having a perimeter sized to be received within the aperture and to seal the reservoir, the middle portion having a reduced perimeter relative to the top and bottom portions, wherein the sight glass is movable between a raised position where the bottom portion is received within the aperture and seals the reservoir and a lowered position where the top portion is received within the aperture and seals the reservoir, and wherein the middle portion allows fluid flow through the aperture when the sight glass is moved from the raised position to the lowered position. 2. The master cylinder assembly of claim 1, further comprising a gasket within the aperture, the gasket being compressed between the top portion and the cover when the sight glass is in the lowered position and being compressed between the bottom portion and the cover when the sight glass is in the raised position. 3. The master cylinder assembly of claim 1, wherein the top portion includes a top flange that has an increased perimeter from the top portion, the top portion resisting movement of the sight glass into the reservoir beyond the lowered position. 4. The master cylinder assembly of claim 3, wherein the top flange includes a tapered top edge. 5. The master cylinder assembly of claim 1, wherein the bottom portion includes a bottom flange that has an increased perimeter from the bottom portion, the bottom portion resisting movement of the sight glass out of the reservoir beyond the raised position. 6. The master cylinder assembly of claim 1, wherein the sight glass is hourglass-shaped. 7. A motorcycle comprising: a frame; a front wheel rotatably coupled to the frame; a rear wheel rotatably coupled to the frame; and a braking system selectively operable to slow rotation of at least one of the front and rear wheels, the braking system including a master cylinder assembly having a housing, a cover coupled to the housing to define a reservoir adapted to contain a fluid at a level, the cover including an aperture, and a sight glass received within the aperture and adapted to indicate the level of the fluid within the reservoir, the sight glass having a top portion, a bottom portion, and a middle portion between the top and bottom portions, the top and bottom portions each having a perimeter sized to be received within the aperture and to seal the reservoir, the middle portion having a reduced perimeter relative to the top and bottom portions, wherein the sight glass is movable between a raised position where the bottom portion is received within the aperture and seals the reservoir and a lowered position where the top portion is received within the aperture and seals the reservoir, and wherein the middle portion allows fluid flow through the aperture when the sight glass is moved from the raised position to the lowered position. 8. The motorcycle of claim 7, further comprising a gasket within the aperture, the gasket being compressed between the top portion and the cover when the sight glass is in the lowered position and being compressed between the bottom portion and the cover when the sight glass is in the raised position. 9. The motorcycle of claim 7, wherein the top portion includes a top flange that has an increased perimeter from the top portion, the top portion resisting movement of the sight glass into the reservoir beyond the lowered position. 10. The motorcycle of claim 9, wherein the top flange includes a tapered top edge. 11. The motorcycle of claim 7, wherein the bottom portion includes a bottom flange that has an increased perimeter from the bottom portion, the bottom portion resisting movement of the sight glass out of the reservoir beyond the raised position. 12. The motorcycle of claim 7, wherein the sight glass is hourglass-shaped.
