Bottomed out front suspension help?

253 Views 10 Replies 4 Participants Last post by  Gearheaded
I have a 2020 R1. Hit a pretty big pothole broke the front wheel, bottomed out the front legs and twisted the alignment to the right.

Looking for advice on what to do with the fork legs and upper and lower triple tree. Inspect and Rebuild? Or just replace everything? Thanks in advance for the time and help everyone.

Agreed- hopefully the forks are just shifted in the triples. Have a headlift front stand ? If not you’ll need to get the front supported up without using forks. Remove the front wheel/loosen clamps just enough to be able to slide forks. Use the lines at top of forks to gauge height. Make sure all is straight/even and try it out. Good luck!
Typically I agree, but it’s actually better to line the axle centerline with the bottom of the bottom fork leg. You want to match the center line of the axle between both fork legs. Using the top will get you close, using the bottom will get you perfect.

OP. Pics would help, 👍🏻

No s#!t right. Cast magnesium on the 2020+. But I feel like the wheel failed as designed and absorbed most of the impact. Definitely will let u guys know. Can't wait to get up again.
No wheel is gonna take that header and survive. I’ve seen it in steel wheels just as easy.

I wouldn’t worry about fractures in the internals. As Jimmy said, seals and oil, and ride it. See how it feels first before you drop a grand into a fork set that doesn’t need it. The triples are most likely solid, and it’s probably just the wheel. I’ve had some really nasty crashes and never had a problem with the triple, it’s usually just other bent wheel or bent fork first.

the internals aren’t a cartridge like others have been, it would be hard to pull it all down to parts for examining. Not impossible, but you need to break the loctite inside the tubes and you need special tools.

personally I think because they’re sprung with fluid, they’re only going to compress so far before they will simply just force the fork legs to bend or snap. If your forks are straight I’d say the internals are most likely ok. Ride after a fork service and new wheel, see what happens first. It won’t be dangerous, it’s not like the suspension won’t work anymore, it just won’t feel smooth or “right” at first. There isn’t much in there that can go wrong.
