Mine looks OK still, but I'd be interested in some data gathering. If you've had some warpage/damage of the part, please do post some info:
For me it would be:
Bike: US 2013 FZ8-N (not CA)
Miles: 7,085 (11,402km)
Rider weight: 240lbs geared (109 kg)
Max including passenger: 410lbs geared (186 kg)
Significant events: no crashes, drops, major potholes, etc.
Suspension:
Stock
Rear preload: max
Front preload: +4.5 flats (not sure how to measure this)
Damping: factory settings
Static sag: 41mm front / 41mm rear
Please note, I'm still fine - I'm just trying to gather some ideas as to what might be causing this. Ideas I'm floating:
- Spring/damping too soft, causing it to bottom out
- Preload too high for rider, increasing momentary shock
- Wrong metal provided by supplier (any metallurgists watching?)
