Thank you all for your advice. I finally bought WilliamTell's lovely Honda CBF600NA ABS.
I have read through the threads and found a few recommendations for instructors for the Grundkurs -
1. Urs from Tramstrasse100 (no idea about price).
2. Mathias from Fahrschule Barmettler (190*3 = 570 for Grundkurs)
3. Pauli from Fahrschule Pauli (170*3 = 510 for Grundkurs)
Any personal impressions/experiences with any of them or more would be great
Also, I need to find motorcycle boots. Ricardo is failing me
Is Polo the best choice?
Thank you in advance for your time
