Tube -BGM PRO- 3.00-10, 3.50-10, 90/90-10, 100/80-10, 100/90-10 - valve position type Lambretta

BGM inner 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 expenses in production, but we think that the result justifies the costs. Air valves have been vulcanized according to model specifications.

• Valve stem position 45° like the genuine Innocenti tube
• No rubbing against the rear suspension linkage pin!

TIPP: 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 minimises friction of the tube.
Thus maximising 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 favour of higher quality for tire sizes up to 100/90-10.
