Conversion of a Lui 50 to a Lui 75

The Lui range is not only a groundbreaking design, but also a lot of fun to ride. At least as long as the engine does not meet the original specifications. With 1.5 hp at the crankshaft and a top speed of a claimed 38.5 km/h / 24 mph, the original 50 cc engine is a pain to ride.

Compared to the Lui 50, the 75cc models are a much more grown-up affair. The large headlight unit with high and low beam, a rear light and other features make them look much more grown-up. And they work that way too.

Thanks to the hype and excitement about the Lui range, which probably started with the first Lui Dolomiti Experience, the spare parts and tuning situation is better than ever. And you can easily upgrade your 50cc model to the specifications of the 75cc model.

For more details, here is the model history for both models in one link:

We have created a wish list with the most important components to carry out the conversion:

And on the test bench with the later configuration it looked like this:
