These bells are great. They're based on a classic design that's been in place for many years and I suppose because they work well, no reason to change it.They just sound really nice, they have a really great sound that decays slowly. it never fails to get attention.I've got them on all my bikes now the only downside I would say is that they are a bit bulky bigger than your little discreet ones. but you know you can't have everything . Having said that they do do a range which are smaller , sounds good, but I'm old school and I like the Japanese know how that went into designing these.
