Vespa tuning project of our own making: By far the most elaborate Vespa conversion from our Vespa workshop, into which we have poured all our know-how and the accumulated experience from 15 years of Vespa tuning, repair work and customizing - the idea for our Superlow Series originated from this custom Vespa.

Vespa chassis - 240 hp

The chassis tuning in this Vespa project starts with the bodywork:
A PX frame was combined with a GS rear end; in conjunction with the small side panels adapted for the hybrid body and the GS fender, only the brake pedal remains as a distinguishing feature.
The advantage of combining the Vespa PX and GS is the flatter steering head angle of the PX body compared to the GS models, which leads to significantly better straight-line stability and also offers the possibility of lowering the Cosa Superlow fork even further by turning down the lower steering bearing seat, without the fender hitting the frame or caliper.
The GS rear end is significantly shorter compared to PX or Sprint models, which, in conjunction with the small "lamp down" side panels, contributes to a super-compact overall appearance - next to normal largeframe Vespas, the PS 240 looks like a smallframe, with the center of gravity even about 20mm lower than that of a Vespa 50N.
Vespa tuning means harmonious components: The braking system has a lot to do on this Vespa custom, so for the front Vespa disc brake we naturally opted for the Scooter & Service 4-piston radial brake in conjunction with a floating Stage 6 brake disc and the Magura radial brake master cylinder with 12mm piston - this Vespa disc brake makes the front tire cry even with just 2 fingers and quickly makes the rear wheel light.
High-quality Vespa shock absorbers - does that actually make much of a difference?
Yes: The shock absorbers are absolutely crucial, especially for faster Vespas - the front Stage 6 Vespa shock absorber is not only adjustable in rebound and compression damping as well as spring preload, but also has the so-called "High-Low" control, a progressive adjustment option for the compression speed.
Together with the BGM Pro rear shock absorber, the PS 240 definitely has the best Vespa shock absorbers available on the market - especially on uneven country roads or when braking before corners, new worlds open up for the dedicated Vespa rider in terms of chassis stability and handling - Vespa tuning at its best.

Vespa engine tuning - 240 hp

The engine of the Custom Vespa PS 240 is based on a Rally 180 engine case with PX 200 Lusso gearbox - normally we use a Vespa PX 200 engine case for the Vespa-Husqvarna conversion, in this case a very well preserved Rally case was available.
To better absorb and distribute the immense forces of the Vespa engine, a screwable reinforcement construction was developed - the adapter plate for mounting the 250cc Husqvarna cylinder has, in addition to the 4 inner screw points, 4 more screws that prevent the adapter plate from bending.
Having already built an engine of this type in early 2007 that delivered 52 hp at the rear wheel, we are focusing on different priorities for this Vespa tuning project:
Everyday usability, smooth power delivery, broad bandwidth, reliability, TÜV compliance - the engine was therefore "de-enhanced" overall, so that we are completely satisfied with 38hp rear wheel power in this Vespa tuning project.
The crankshaft is based on a Mazzucchelli long-stroke full-circle crankshaft for Vespa PX 200, which is equipped with an eccentric crankpin for a 62.5mm stroke, a connecting rod machined from solid material in a special length and tungsten weights to balance the translational masses.
The clutch of this Vespa is of course our in-house Vespa Cosa clutch with CNC-machined clutch basket and clutch inner part - a conventional Vespa clutch would not even come close to withstanding the stresses.
The exhaust on this custom Vespa is a one-off, handcrafted piece made of over 50 stainless steel segments – and, for everyday usability, it features our "Silent" internal soundproofing system. The curved design ensures good ground clearance in corners despite the ultra-low center of gravity. In our opinion, the stainless steel exhaust is a small work of art in itself – the total construction time for this Vespa racing exhaust was approximately 60 man-hours.
