Title: Rechroming Fork Tubes
Post by: Keith Meatyard on July 03, 2014, 09:34:07 PM
I have found a company in OHIO that rechromes fork tubes, and I just had them do a pair of pitted 35mm tubes.  They look beautiful.  Here are before and after pics.  Price is $110 each, $220 a pair for this size tube.

Does the color look like the original? It's hard to tell by the photo. Did you have to do anything special to remove the oil?
 My local chrome shop will do rims for $100 but won't touch an exhaust because it contaminates the tank.

Rechroming fork tubes is a different process than decorative chrome.  The fork tubes are hard chromed like hydraulic cylinder rods, and there has not been previuos success in the US finding someone to work on the motorcycle fork tubes.  As far as the color, they look like brand new tubes.

Sometimes rechromed tubes are not quite the same size and fit looser in the bushings and do not seal as well. One potential drawback.

Again, this is not decorative chrome plating, nor is the outside diameter achieved by turning.  The diameter is finished by precision grinding after the chroming.  I measured down the lengths of both of these tubes.  Result = 1.377"/1.378".  When slid into the lower legs, they feel as tight as new forks.  

In past posts, members were looking for ways to restore pitted forks with no luck in the US.  The comments regarding the replacement forks was that the metal was not as strong as the originals.  When I called one of the replacement vendors and inquired about the grade of steel they used, they said 1026.  1026 is way down the list for strength.  Does anybody know the grade used originally?  I would think a grade in the order of 4140, and heat treated, stress relieved.
