This one is a Honda - not sure which model yet but definitely a four-valve four stroke.. I think its a XR400 with the 2 pipes in front
The only image stronghold has that shows an XR is the first image. The others are CR's. Probably 125 or 250. Notice the header pipe is a 2 cycle pipe. It's either an XR250 or 400 with some extensive suspension mods and plastic is after market as is the gas tank.
