The sound of a V8 on the boil can be intoxicating. Here’s one that is probably the least powerful you’ll see, but it’s still amazing. The video quality is not the best, but the exhaust note makes up for it.

Denny Franz is a master machinist who loves multi-cylinder bikes. After building a 700 cc V8 bike out of a BMW R65 and two Honda CB350F engines, he set his sights on a slimmer, trimmer, more carefully engineered, and more authentically vintage-styled machine. The result is the 400cc Franz Flyer, and it’s a truly glorious way to go not very fast.
