BGM inner tube (Lambretta and Vespa small frame) 3.00x10, 90/90x10

Made specifically for Lambretta and Vespa small frame models with the tube properly offset and will the following tire sizes:

• 3.00-10
• 90/90-10

BGM tubes have been produced according to our specifications to meet the demands of Vespa and Lambretta scooters. The butyl ratio is above 50%, which makes them extremely airtight and perfectly reliable. The high butyl ratio leads to high expense in production, but we think that the result justifies the costs. Air valves have been vulcanized according to model specifications.

TIP: Use mounting paste on the bulge to fit the tire and sprinkle the inner side of the wheel with talc. Mounting paste ensures the correct final position of the tire, while talc minimizes friction of the tube.
Thus maximizing safety and endurance of the tube.

NOTE: Tubes with a smaller butyl ratio have a higher percentage of rubber, which leads to more flexibility. They can therefore be used for a wider range of possible tire sizes (up to 130/90-10). You'll have to deal with the disadvantage of the tires been a lot less airtight. We have decided in favor of higher quality for tire sizes up to 100/90-10.
