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

you should get new one under warranty

Weird. I looked and my 2020 GT doesn’t have the casting mark. Curious why some have it and other Rockets don’t. Could it be later models have them and early models don’t? Probably not a big deal but just curious why.

I have tried - Triumph claim that this casting mark is present on all Rocket 3 and is part of the manufacturing process and is not a defect - Triumph also say that the casting marks are hidden by the standard exhaust and because of this is acceptable - Triumph would not recognise it as a defect and would accept the warranty claim - I am disappointed that Triumph think that this is acceptable on such a premium expensive bike - Thanks Mark
