Rocket 3 R storm Swing Arm Casting Marks

[Buelliganman]

After fitting IXIl exhaust on my 2025 Storm R I noticed a casting mark underneath the paint finish on Swing Arm - Contacted Triumph via my local dealer and was told that this mark is a Casting Mark and not a defect and is normal and present on all Rocket 3 models - it is usually hidden behind standard exhaust - has anyone else got this mark on Swing Arm ??

I have something there, very slight. Not as pronounced as the one in the second picture. I wouldn't worry about it if it were me.

Hi Rok - Thanks for your reply - the first photo is my bike - the second photo a mate found on Facebook on his phone - I thought it was a defect but Triumph insist it is normal and on all Rocket 3 swing arms - just felt like I was being fobbed off nice to know other owners have noticed this - Thanks again Rik
