Custom SIP & Butcher Garage "Project ESC"

In 2018, this custom project was launched together with Butcher's Garage from St. Petersburg. At the time, Alex Mazan wrote:

We here at BUTCHER GARAGE have been SIP Scootershop customers from the very beginning. It's no secret that in Russia it's often not easy to get all kinds of things - but when it comes to Vespa parts, SIP Scootershop makes life very easy for us. We call the almost 1,000-page SIP catalogue "the bible" in our workshop, only half in jest. Because of this long and close collaboration, it has always been our wish to work together on a custom project. We particularly like "scrambler" conversions, which are also a big trend in the motorbike sector. Every motorbike manufacturer now has a scrambler model in its portfolio.

We started to check whether such a conversion could be feasible with a classic Vespa. There have been many Vespa-based projects made for cross-country or desert racing. But in our opinion, they were mostly rather poorly functioning conversions that could only impress visually. We decided to combine actual off-road characteristics with urban design and develop an excellent model to escape from the urban jungle - the idea for the ESC "ESCAPE" project was born!

The search for design solutions lay mainly in the motorbike construction of the 60s to 70s: a saddle in the style of the early BSA motorbikes and the tank of the Husqvarna 70, which matched the PX frame surprisingly well, were a start. Being able to build without restrictions or specifications is a great advantage in any job, and the only condition from the SIP guys was to use some of their own beautiful products for the project. The people from Metal DIY helped us a lot with the frame construction, together we determined the geometry of the future bike, the wheelbase, the steering column angle, the ground clearance and the height of the saddle and welded the body parts of the new project.

The head tube, for example, comes from a pit bike. The rear suspension was elaborately implemented on two SIP Performance shock absorbers, which works excellently in driving. Due to the lever of the transmission force in the horizontal plane, based on the pendulum swing arm of the PX steering column, it was possible to build a system with a central damping position. The transmission of the shock absorber not only had a good effect on the stroke length and balance, but also on the design, filling the space under the tank and making room for the wide rear wheel with a dimension of 130/90-10. For the front wheel we used a 12-inch spoke rim and a custom hub, specially made for use with the Galfer brake disc.

A real eye-catcher

Final touches

The choice of the SIP Performance Curly exhaust was to serve two functions: better ground clearance and a visual balance between the right and left side of the scooter. Our ESC project received fully hydraulic brakes at the front and rear: a rear disc brake customised by us from SIP Scootershop, SIP aluminium CNC brake calipers with larger pistons, Galfer brake discs, SIP brake master cylinder and Spiegler steel braided lines.

The paint work in the SIP Scootershop corporate colours (white-red-black), based on the design by Anton Gorbunov, was carried out by our friend Ksenia Deryagina here in St. Petersburg. Despite many sketches in advance, we improved the basic idea several times until we were 100% satisfied. We artificially aged the chequered part, washed out the black squares and covered them with acrylic paint, which cracked the primer of the powder coating.

We also slightly modified the tunnel tail lights from SIP Scootershop and welded them into the tail. According to our conception, the headlight imitates a number plate with sponsor symbols and is equipped with a powerful LED. We developed and installed a sequential gearshift with foot control for maximum resemblance to a scrambler motorbike. As a result, the handlebars look wonderfully light, with no extra gear cables or shift segments. Only the Domino quick throttle grip, the adjustable clutch grip and the SIP master cylinder with the handlebar mounts where we installed the emergency stop switch have remained on the handlebars.

The radiator behind the leg shield was handmade by us for this custom modification. It supplies the water-cooled cylinder head from Parmakit in cooperation with an electric water pump from Malossi. Speed, rpm, water temperature and other values are displayed on the SIP speedometer of the Smallframe Vespa.

Thank you very much, Alex. The custom scooter has now been transferred from Russia to SIP Scootershop in Landsberg and can be viewed in the flagship store. And because this project was just so cool, we have also produced a matching T-shirt for it. More information, exploded views and a detailed parts list can be found on the special page for Project ESC.
