Hand made at 1/3 its designed size, this 125cc V10 engine has a miniature yet throaty roar. Creator Keith5700 explains:

…my references for designing stuff is just to keep plodding away looking at pics, and reading stuff on forums. Most things are designed from scratch these days, but I do a lot of image Googling, looking for pretty things to copy.
