The invention discloses a motorcycle liquid crystal instrument. Sealants are arranged at multiple positions, and consist of the following components in parts by weight: 0.8 part of ultrafine ceramic powder, 1-2 parts of dioctyldilauryltin, 2-3 parts of grapheme, 1-2 parts of fumed silica, 0.7 part of tetrakis-[beta-(3,5-di-tert-butyl-4-hydroxyphenyl) propionic acid] pentaerythritol ester, 22 parts of xylene formaldehyde resin, 1-2 parts of vinyltriethoxysilane, 5-6 parts of polyurethane-modified epoxy resin and 1-2 parts of fatty acid methyl ester sulfonate. As the motorcycle liquid crystal instrument disclosed by the invention is doubly protected under an outer shell and an inner shell, and the sealant is also arranged at the multiple positions, a liquid crystal display control circuit board is protected from water and moisture for a long time, so that the liquid crystal display control circuit board can effectively work for a long time; the sealant can resist high temperature of 76 DEG C, and can resist low temperature as low as minus 27 DEG C.
