Hello, just noticed this group. I am a local classic Lambretta rider – blue and grey Li 150, 1962. I use Etty and Tyler as the owner has worked on Lambrettas and Vespas since the early 60s, possibly longer. They are at 83 Upton lane, London E7 9PB. Old school workshop with a large dog, no frills. They have real mechanical expertise and prices that reflect this.
