Drum Brake Conversion Kit

from 8" to 10" tyres, rear,
for Vespa 125 VNB4-6T/Super
/150 VBB2T/Super/P150S,
incl. brake drum, brake shoes,
dust cover

Size does matter! With our conversion kits from 8" tyre to 10" tyre the chassis quality of the classic model of Vespa is substantially improved. Superior ground clearance, better road holding on curves, optimised directional stability, extended transmission and a clearly bigger range of mountable tyres are the awards of this conversion.

For those who do not use a PX engine but still want to drive on a 10" basis, we offer a drum brake conversion kit. In general, the changeover to a 10" basis results in a considerably more stable braking effect for the rear and the front than the small wheeled system.

The conversion at the front is relatively easy to implement. The supplied dust cover has to be riveted to the swing-arm, which requires a little effort. This suits models with a 1-hole brake shoe attachment, incl. drum brake, axle, brake shoe, speedometer drive and woodruff key.

At the rear the drum brake, dust cover and brake pads are replaced. This only for models with a 2-hole brake shoe attachment.

Apart from the front dust cover all of the supplied components are Plug&Play.


SIP TIP: Due to the lower plunge level subsequent to the conversion, we recommend the use of harder shock absorbers. The conversion also changes the transmission ratio, it may also be necessary to adjust the gears in this case! Do not forget the suitable rims, tyres or inner tube!
