Conversion kits: Brake for Modern Vespa
- at SIP Scootershop
Whoever brakes better wins! Unlike their classic ancestors, modern Vespas are equipped with good braking systems as standard. A disc brake always ensures good deceleration values. If this is then converted to a radial brake calliper or an oversize brake disc, the best possible setup in terms of braking is achieved. With any engine tuning, you should never forget to upgrade the suspension and brakes as well. If you want to accelerate faster, you also have to be able to brake better.
How do I find the right parts to upgrade the brakes on my Modern Vespa?
You are here in the large section for brake conversion kits for the Modern Vespa. To narrow down the selection of products even further, you can now select the exact type of vehicle for which you are looking for conversion parts. For example, if you are interested in everything that concerns the models "Vespa GT/GTL/GTS/GTV 125-200", then make this selection and the display will be much more specific and tailored to you. Using the filters in the left-hand navigation, you can also sort by "brands", "use" and other criteria. If you remove the vehicle type filter, e.g. "Vespa GT/GTL/GTS/GTV 125-200", the entire range for the Modern Vespa vehicle category is displayed. This is always helpful if you are unsure of the vehicle type of the scooter you are riding.

The different models at Modern Vespa
Vespa ET2/ET4 50
The front brake system, also well known from the ZIP models, is rock solid and offers plenty of room for improvement and modification. At the rear, the Ø 110 mm drum brake provides sufficient braking power.
Vespa ET4 125-150
Like the smaller 50cc models, the ET4 125/150 has a solid braking system that has plenty to offer in terms of conversions and modifications.
Vespa GT/GTL/GTS/GTV 125-200
Since the GT/GTL model of 2003, there have been hardly any changes to the front and rear disc brake system. The biggest innovation was the ABS, which was optional from 2014 and has been standard since the Euro4 models of 2017.
Vespa GTS/GTS Super/GTV/GT60 250-300
The GTS 250 was the first Vespa with ABS on the market, which was not yet fully developed at the time. In the meantime, the 300 models are equipped with a decent ABS as standard. Otherwise, the braking system is largely the same as on the much slower 125-200 cc models.
Vespa LX/LXV/S 50
The brake system of the Vespa ET2/ET4 worked so well that it was also transferred to the later LX/LXV/S models.
Vespa LX/LXV/S 125-150
The 125-150 cc LX/LXV/S models also use the braking system of their predecessors, a real update of the front disc brake and rear drum brake was not necessary.
Vespa Primavera/Sprint 50
Since the end of the 90s PIAGGIO has kept the disc brake system of the ET2/ET4, so it is also used on the Primavera/Sprint. Even the 110 mm drum brake is still inserted here.
Vespa Primavera/Sprint/946 125-150
PIAGGIO still uses the rear drum brake on the Primavera/Sprint models. However, compared to the 50 cc models, there is an upgrade in the Ø, so here the 140 mm brake shoes are used. The front disc brake is rock-solid, and has been optional since 2013 and equipped with ABS as standard since the Euro4 models.

The range of conversion kits for brakes on Modern Vespa at SIP Scootershop
Conversion to oversize brake discs
Larger brake disc diameters lead to better braking results. Matching adaptors make it possible to mount them on Modern Vespa. The brake discs from ZELIONI are a visual treat and decelerate enormously.
Conversion to radial brake calipers
Radial 4-piston brake callipers achieve significantly better braking values than the usual axial brake callipers. No wonder, then, that people now like to convert to radial brakes not only in racing but also on the road. They are available for both front and rear. Matching axle seating allows the brake callipers and shock absorber to be mounted and is the most elegant solution. Somewhat easier but also cheaper is the use of an adaptor. Products from OTTOPUNTOUNO, AF PARTS and SIP PERFORMANCE are at the forefront here.

Legal or not legal - that is the question here
We have marked many brake parts "For racing purposes only", as this is a modification of the chassis. An optimisation of the brake system that leads to better braking performance is certainly welcomed by all test centres.
If you want to use your brake conversion legally in road traffic, you should always consult a TÜV office. Many items, such as brake discs and brake pads as well as brake callipers, have a KBA number and can therefore be legally used in German road traffic. There used to be a parts certificate for the GRIMECA disc brakes, which is now only available as a copy. However, these disc brakes are also approved by most TÜV authorities on the basis of individual appraisals. If in doubt, clarify conversions to oversize or radial brake pumps. In any case, we recommend that you have them fitted by qualified personnel if you do not feel able to do it yourself.
