The invention discloses a novel motorcycle liquid crystal instrument. Sealing gum is arranged at a plurality of portions and comprises, by weight, 1 part to 2 parts of coumarone resin, 2 parts to 3 parts of zinc dialkyl dithiophosphate, 8 parts to 9 parts of xylene formaldehyde resin, 1 part to 2 parts of terpene resin, 2 parts to 3 parts of fumed silica, 1 part to 2 parts of homopolymer of 1,2-diydro-2,2,4-trimethylquinoline, 7 parts to 8 parts of dimer acid modified epoxy resin, 1 part to 2 parts of triethoxy ethyl silane and 2 parts to 3 parts of alcohol ethoxylate carboxylate. According to the novel motorcycle liquid crystal instrument, a panel and an outer shell are firmly connected, dual protection of the outer shell and an inner shell is achieved, the sealing gum is further arranged at the multiple portions, the long-time waterproof and moisture-proof effect on a liquid crystal display control circuit board is guaranteed, and the liquid crystal display control circuit board can effectively work for a long time. The sealing gum can be resistant to the high temperature of 71 DEG C and the low temperature of -22 DEG C.
