Yep I was thinking of a lighter progressive spring set up ....never heard of things snapping before just blown seals but I tend to agree with heavy riders / wrong spring having something to do with it
People do this so they don’t have to pay eBay fees ....just advertise the valve and cap and wait for people to contact you ...saves you loads of money when your talking Thousands
Why would anyone spend thousands of pounds on a bike only to get it home and start spending more money on so called upgrades .....my advice would be to get on it and ride and enjoy what you have,there brilliant bikes from stock and if you break something then replace it..
