This Fabulous Tiny 125cc V10 DIY Home built Engine Runs and Is an Absolute Work of Art

Needs to be in something.

This model V10 has fuel injection, a dry sump oil system, and a triple plate clutch. But this isn’t just a model, this is a one-third scale model that displaces 125 cc… and it runs.

That’s incredible.

The build, which started in 2014 and is documented here, is beyond meticulous. The builder, Keith, was looking for a challenge as he had already built a V8 and has seen a number of scale V12s, but hadn’t seen anyone build a scale V10. So he went for it. And we mean really went for it.

He fabricated the whole thing himself, which is crazy to think about. It took nearly three years to build, but look at what he’s created. As far as we know, it’s the smallest displacement V10 this side of the Connaught Type-D GT’s 2.0 liter supercharged V10. This has to be one of the most beautiful replica engines ever built. But it’d be a shame to have it sitting on a table for the rest of time. It needs to be in something.

How about a go-kart? Most go-karts have single cylinder engines that can range from a Briggs & Stratton four-stroke to a 100 cc Yamaha to a 125 cc Rotax or engines taken off dirt bikes. Isn’t this a more elegant solution? We think so.
