lui 50 to 75

The lui range is not just a ground-breaking design, it is also a hell of a lot of fun to ride. At least as long as the engine is not to original specs. The original 50 cc engine is a pain with 1.5 hp at the crankshaft and a top speed said to be 38.5 km/h / 24 mph.

Compared to the lui 50 the 75 models are a much more grown up affair. The big headlight unit with hi and low beam, a rear brake light and other features make it look much more grown up. And also work like that.

Thanks to the hype and craze about the lui range probably started with the first Lui Dolomiti Experience the spare and tuning part situation is better than ever. And you can easily turn your 50 into the specs of the 75 one.

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

We started a wish list with the major components to carry the conversion out:

Also in this listing is the new Casa Lambretta 80 cc kit. We did something on that before ->


Finally, we had it on the dyno with the SH20 original carb, air filter box and the lui 75 original exhaust. The SH20 was jetted like this for best performance and reliability:

Main jet:             65
Idle jet:                48
Atomiser:            5899-5

A very good result with the Innocenti prototype turned into reality by Casa Lambretta. Especially considering this test earlier with the 75 cc cylinder kit give a maximum of 4.9 hp at the rear wheel. At here we have on a fresh -not settled in- engine and kit 5.5 hp straight away. 

If you fancy more power on a 50 cc or 75 cc lui engine the Casa Performance ONE05 kit is the way to go. We also tested it with on the lui 75 with original exhaust and the SH20 carb.

With the standard 75 air filter box the jetting of the SH20 was:

Main jet:             76
Idle jet:                45
Atomiser:            5899-5

With a modified 75 air filter to 6T's Tuning Manual spec the jetting of the SH20 was:

Main jet:             85
Idle jet:                50
Atomiser:            5899-5

And on the dyno with the later setup it looked like this:

So some choices here and we have -sadly- not yet tested the ONE35 kit!

So stay tuned!

Part 1: What or who is Casa Lambretta?

You can answer that relatively matter-of-factly. Casa Lambretta will Founded in 1980 by Vittorio Tesserato improve the supply of spare parts for the Lambretta. At a time when the Lambretta is being treated like an absolute stepchild, and not just in Italy. Almost forty years later the Lambretta is more popular than ever before and Casa Lambretta has made the range so broad and deep that the spare parts supply is better than ever. From parts for the Model A to those for the dl 200, almost everything is available today: Casa Lambretta shop


Most important parts supplier worldwide

Casa Lambretta is much more than the -probably- the world's most important parts supplier for the Lambretta. But we'll get to that another time.

You will find Casa in Rodano, part of the metropolitan city of Milan (formerly the province of Milan). Not far from Linate Airport and approximately 15 minutes from the Centro Studi and the former Innocenti factory premises in Lambrate.

And here, in his origins, lies one of the reasons why Vittorio, fortunately for us, focused so much on the Lambretta. This is how Vittorio tells us:

“I want to make one thing clear, I'm not a scooter racist. I like you all Vespa, ISO, Lambretta, Moto Guzzi, Gilera. These are all important and beautiful contemporary witnesses of a bygone era, from whom one can learn a lot. However, after a few years I had to commit myself for organizational reasons. And since the Lambretta was born in this region, it was my homeland's reputation to choose the Lambretta. "Vittorio Tessera, Casa Lambretta

Casa Lambretta moved into the current business premises in 2010. Shortly afterwards we visited him in order to bunker parts before the Italian summer break and to help our then and now current Julia with the acquisition of her first Lambretta. A wonderfully beautiful SX 150. We reported here.

Prodotto in Italia

Meanwhile, Vittorio is in the building 800 square meters of his parts warehouse, the workshop for the three permanent restorers (Mario, Maurizio and Fabio) and his new study. 95% of Casa Lambretta parts are made in Italy. The small percentage of purchased parts is usually marked with an A (= Asia) in Vittorio's parts lists in the Origin category. Vittorio's wife Orietta keeps track of the orders from the Casa Lambretta concessionaires. Greetings to everyone!

Museo Scooter & Lambretta

This is located above the business premises Museo Scooter & Lambretta. We already reported here -> Casa Lambretta Museum, but will also start again here and present the museum, its concept and the exhibits in it in detail.

Casa Lambretta Concessionaire Germany

Since the Eurolambretta 2003 that is Scooter Center of Casa Lambretta concessionaire Germany and we fondly remember how we, with our friends Roberto Graupner and Markus Fröschen (also best regards!), wrapped up the deal with Vittorio in Assisi. A long-term and intimate friendship has grown beyond the pure business relationship and the love for Lambretta.

So it goes on

In the next few episodes we want to show you the development of the quality of Casa Lambretta parts using a few examples. Introduce the museum and the exhibits in detail and take a look at the beginnings of the Casa Lambretta company. Above all, on how Vittorio just shortly before recovered important documents and scooters from the factory.

Get around betta, the Lambretta!
