70bhp Vespa – Something Special from SIP | CUSTOM
SIP are celebrating their 25th anniversary this year and what better way to celebrate than to build one of the fastest, longest Vespa PXs around? A scooter that was built to bring to life the company motto “Performance and Style.”
With 70bhp on tap and some serious modifications, this is one custom scooter that will certainly live up to its ‘Something Special’ name…
Not just for show
SIP wanted this scooter to look the part AND impress on the sprint track so they utilised the powerful BFA 306 engine. It’s around 50bhp out of the crate but that wasn’t good enough so they tuned it.
SIP’s main man, Ralf said “We left no stone unturned in our quest to create something just a little bit special and fully explore its explosive potential. It is currently pushing out 71PS (70bhp), measured at the rear wheel! This power is transmitted to the riding surface with the assistance of an electrically operated sequential gear selector mechanism. The push of a button on the steering assembly is all that is required for rapid gear selection”.
That’s a hell of a lot of power being pushed out of what is essentially a cut-down Vespa frame, obviously, that power needed some kind of taming.
Cut and shut
They lengthened the frame to give a wheelbase equal to a Lambretta, they also shortened the headstock by 10cm and lowered the frame at the back end by 8cm. The legshields were also lowered and moved forwards.
So how did they stiffen it?
They didn’t want to go down the usual welded in the centre of the frame bracing option seen on various sprinters and race Vespas. Instead, they modified the frame internally by welding in steel tubing and the red skeleton running from the top of the legshields to the rear of the floor runners. Not only does the bracing provide extra rigidity but it also gave SIP the perfect way to route cables and electrics through the frame spar.
The fuel tank was also relocated into the central footboard tunnel and welded permanently into place to further increase strength. It’s never going to get you far between fill-ups but this is only built for 1/4 mile sprints.
Metalflake is enjoying something of a renaissance at the moment. Once the preserve of 1980s customs, flake is back in a big way.
SIP wanted this paint job to be ‘in yer face’, it’s loud, proud and has old-school influences to reflect their 25th-anniversary ‘silver’ celebrations. I think they fulfilled that brief very well.
See it in action
If you want to see and hear what a 75bhp Vespa goes like you can see it in action at SIP’s Landsberg HQ in Germany on July 27th during their second annual Tacho Karacho sprint event, or at one of the German DBM race events.
