Umrüstkits: Fahrwerk für Vespa 125/150/Rally – bei SIP Scootershop
There are many reasons why you should replace and improve the suspension on largeframe scooters. The more powerful the Engine is, the better the suspension should be and the older the Largeframe Vespa is, the worse its original condition is. Riding and touring with the original setup is only pleasant to a limited extent. Another important reason is the appearance of the Largeframe Vespa. Many of the conversions make them unique and make them stand out from the crowd, which is not necessarily a bad thing.
For which largeframes are there Conversion Kits for the chassis?

Here is an overview
Conversion to 10'' 110-130 mm rear tyres
The classic Wide Tyre conversion for Largeframe Vespas. The rear wheel can be converted to a width of 130 mm or the mighty tyre circumference of a 120`90-10 Tyre. A modification of the Engine Swing Arm Pivot is necessary for this.
Conversion to 10" 100 mm front & rear tyres
100 Tyres are approx. 1.2 cm wider than the standard 3.50-10" tyres on most Vespas. If you want to safely use this first stage of Wide Tyres on a Vespa, you need slightly wider rims to ensure safe contact with the rim flange.
Conversion to 10" front & rear tyres
With original 8" or 9" tyres, potholes turn into pits, the Vespa will bottom out in bends and flutter at high speeds. Converting to 10" Tyres brings a significant improvement here. Conversion forks, conversion rims or brake drum conversion kits are the solution here.
Conversion to 11" front & rear tyres
The Rim with sizes 2.50-11 and 3.00-11 is the ultimate solution for Wide Tyre conversions and the latest addition to the SIP Wide Tyre conversion kits. The 11" conversion is discreet, harmonious and only catches the eye at second glance.
Conversion to 12" front & rear
Glorious Basterd - Life begins with 12". Weeks of development and many, many prototypes were necessary to develop a conventional solution for the Vespa community. Problems such as tracking, steering behaviour and frame spacing were successfully solved. The result is better chassis quality thanks to more ground clearance and optimised directional stability. In addition, the 12" wheels are an absolute eye-catcher and extend the gear ratio.
Conversion to ZIP/ET4 suspension
When using a PIAGGIO ZIP SP Steering Column, the Suspension Arm is positioned on the left-hand side. The larger selection of high-end Shock Absorbers (all from the PIAGGIO ZIP) with a large Fluid Reservoir External, the shortened wheelbase and the modified geometry are the major advantages of this Steering Column. Added to this is the strikingly different look.
Conversion from 10" to 8" rear tyres
Various 8" Tyres are available for classic Vespas front and rear. Also available as complete tyres.

Customers ask - SIP answers
"Can I do the conversions myself or do I need a specialist workshop?"
As with most conversions on classic scooters, you can do it yourself. The conversions are not so complicated that you would need to be trained as a motorbike mechanic. Many of the kits are largely ready to install. Nevertheless, you should of course not have two left hands. But the beauty of Vespa and customising is that it's model building on a large scale. If you are unsure, don't have the tools or simply don't have the time, we recommend going to a tuning workshop. We can also recommend one if you don't know one in your neighbourhood.
