Just wanted to post my experience with Cafe4Racer since they sell a lot of Brick parts for custom builds:
I have purchased MANY MANY parts from this company for a k1100 ground-up build, probably well over $2000 in parts. Such a build takes quite a while to complete, as Im sure you can guess. So the problem is that I purchased an exhaust collector from them to build out my custom exhaust. I purchased this near the start of my build in early 2022, so it has been a little while since the purchase. I did not get my bike fully assembled until about 1 month ago when I finally got the bike started again. The collector failed on all 4 header pipe connections within 3 rides. The failure was a perfectly clean break at the "welds", which were not so much welds but rather weak tack welds.
When I contacted them about this, they ignored my email. I resent the email 2 more times, still ignored. They only finally replied when I called them out on a public reviews site, and basically said too bad. They didnt attempt any communication to reconcile or address an issue with a customer that has spent 1000s with them. Just keep that in mind if you want to order anything from them, they arent likely to stand behind their product at all.
If there is a better place to post this in the forums please advise, Im happy to post this in a more appropriate are.
