Rim Tubeless SIP for Lambretta

2.10-10", aluminium, polished,
KBA 50164, valve premounted

Road legal on the Road!

The SIP rims have received official type-approval. The rims got the German KBA numbers. They managed all the necessary tests for a legal road-use on German roads. For sure, this will help also to legalize it in other countries.

Innovation in style, engineering and security. The new SIP tubeless rim, successful and reliable. This rim allows you to use tires without a tube. In case of a puncture a sudden air leak will be prevented, the air pressure will decrease slowly. Blown tires will be a thing of the past. So will valve tear offs or punctures due to tubes beeing trapped between the rims during assembly.

The SIP tubeless rim combines the advantages of a classic cast rim with a high production accuracy and quality. The design is a tubeless double hump rim. This hump prevents the tire from slipping into the rim well in case of a puncture. The rim rotation is very precise. The rim is aluminium cast and CNC machined. The surface finish is perfect. The valve is included and already mounted.

The rim is currently available in polished aluminium, black, black with polished edge and silver.


2.10-10: Perfect size for standard tires. The rim allows fitting tires from 3.00 up to 3.50-10. The rim is 2.10 inches which is the same as original. To allow for the deep inner channel in the rim for tyre fitment, Longer hub studs/ bolts are supplied with the rim. 

SIP has been successfully verified by the German ministry of transport and is now officially recognized as approved vehicle component manufacturer. The SIP rim 8103 has also received official type-approval. From May 2015 on, the rims SIP 8103 got the German KBA number 50164. They managed all the necessary tests for a legal road-use on German roads. For sure, this will help also to legalize it in other countries. The chromed version comes without KBA number. There we plan no homologation yet.

Attention: Please contact a qualified workshop for accurate and damage-free tyre fitting (tire tool and appropriate fitting basis highly recommended). By all means make sure to avoid any damage to the surface! A lot of tube-type (TT) tyres can also be used as tube-less (TL) tyres. When mounting the tyre, make sure to use mounting paste. If you use oil or other inappropriate lubricants, the tire won’t sit firmly on the rim. Danger! Make sure to always check clearance of engine and accessory parts!

If you have doubtsm, that you can mount the tyre, order the rims with already mounted SIP Performer tyre on.


Jockey, Jockeys Boxenstop, Germany, November 2010 : ''I've mounted these rims on fifteen different styles of the Vespa drum brake units. The wheel fits them all wonderfully, apart from the Spanish produced rear brake drum. Michelin S1 tyres could be mounted with no problem, even though our tyre mounting machine was designed for larger diameter wheels and tyres. The safety bead feature has proved very effective and successfully prevents the tyre from becoming completely unlodged in the event of any loss of air pressure. In order to prevent any unnecessary damage to these aluminium wheels we recommend that used tyres be cut off during the replacement procedure.


Jockey, Jockeys Boxenstop, Germany, May 2011 : ''We treated the tubeless Lambretta wheels mercilessly throughout the whole of the Spring Race. Eleven hours non-stop and still going strong! Nice one! Sweet greets from a rapid Lammy!''

Dean Orton, Rimini Lambretta Centre, Italy, 18.06.2013: " During this years Moto Giro D?Italia, living Lambretta legend Tony Tessier was competing on his scooter when he hit a MASSIVE pothole. The size of the hole coupled with Tony?s size (in his own words he is a ?fat bastard?) actually managed to buckle the rear wheel rim. The Giro mechanics took the wheel off and beat it back into shape with a lead mallet! It was near perfect and good enough to use for Tony to complete the event.

The point is this : the aluminum of the SIP tubeless wheel rims is that good that it was possible to re-shape it with a lead mallet and it didn?t crack. Well done SIP!
