Coupling socket Vespa Largeframe Coupling Actually, one might think that a coupling socket leads a very contemplative life. You will only be required to do some work during the gear changes and when starting up. But as so often in life there are things that make it difficult for you. Power, switching points at higher speeds and light centrifugal masses bring the simple ones on the market [...]
Vespa races in Austria For the fourth time, on April 27.04.2013, 1200, the season opening of the long-distance races was the spring race at the ÖAMTC test area in St. Veit. We, the DART RACING TEAM, took part again of course. The XNUMXm long circuit offers not only relaxed full throttle passages but also tricky sections. The start / finish straight is certainly to be seen as a particular challenge. To […]

Vespa racing engine with 35HP + part 2 Today it's time for the first part of the innards of the Vespa racing engine. Special requirements call for special solutions. The crankshaft is subject to very high loads. It has to transmit the pressure generated by the combustion in the cylinder to the drive in a translatory manner and is subject to rapid jumps in engine speed during racing. Our special shaft weighs almost 2000 grams. [...]

Modern cylinders and exhaust systems nowadays bring very powerful engines to the Smallframe Sector. Combinations such as the Polini Evo with a Big Bertha on our Generation XI, lift over 24Nm over the rear wheel onto the road. The power flow between the crankshaft and the rear wheel is routed through the clutch. All coupling components are subject to the highest stress, therefore [...]

To do the first dyno runs, we just had to fit the cables. You might remember? The engine came at least the idle and main jet, while the needle were missing. The needle is very important for a smooth engine run and picking the right one can be tricky. In our online shop, you can […]
The trains were assembled quickly and we are looking forward to the first runs! The engine came to us with thrown jets: without a needle, with a 50 secondary jet and a 150 main jet. The needles in particular are the sticking point when it comes to tuning. It is often quite difficult to pick the supposedly right one from a seemingly endless range of carburettor manufacturers […]
