The invention discloses a motorcycle engine. The motorcycle engine comprises a variable speed drum, a shifting fork and a hand feeling lifting device, wherein a casing pipe on the shifting fork is arranged on the variable speed drum in a sleeve connection manner; the hand feeling lifting device comprises a through hole formed in a neutral gear section of the variable speed drum and a stopping hole formed in the inner wall of the casing pipe; and an elastic stopping part is arranged in the through hole. When the casing pipe of the shifting fork reaches the neutral gear section, the through hole in the neutral gear section is communicated with the stopping hole, the top of the elastic stopping part enters the through hole so as to increase resistance between the casing pipe and the variable speed drum; and when other gears need to be engaged, firstly external force is needed for overcoming the resistance, so that the elastic stopping part returns to the through hole under the pressure of the casing pipe. Therefore, a driver has obvious operation feeling when the motor engine engages a neutral gear, thereby effectively avoiding the occurrence of wrongly engaging gears, improving the safety of motorcycle driving and reducing the probability of accident occurrence.
