Although somewhat old and smelly(a given) I had not come across this subject before. A friend on another forum, who has just added a new 1800 Gold Wing to his stable, linked to this. He then linked to this UK equivalent(ish) Dyna Beads My major problem locally is that there is nobody who can properly balance bike wheels. As they don't make the Wing things in BMW sizes and don't reply to emails, the useless twats, I thought I would try the beads as they can be claimed against my business. They seem to work OK and if they 'do what it says on the tin', then having balanced wheels right through to next tyre change(beads are reusable) they are a definite plus. No connection etc.
