Sure, they're heavy, but every piece is solid, precisely machined out of quality materials for a predictable "no-hassle" fit every time.
They are either powdercoated (as is this), polished or plated with a deep flawless chrome, and although it's something you can't quite put your finger on, what transpires is a feeling of Quality that's hard to match.
This handlebar clamp is a prime example of why these motorcycles are just so easy to like. As always with photos it may not be easy to capture an object's "feel" but if you can, extend that to the rest of the motorcycle.
The whole bike is made like this, so of course the finished product is one that conveys a constant feeling of reliable quality. What's not to like?
