  • How do I remove corrosion of front forks?

    How do I remove corrosion of the front fork? I believe the actual surface is aluminum and is smooth as. I cant feel any bumps, so it cant be dirt or scratches from the road.

    The bike was bought from someone whom lived in Bunbury, so possibly corrosion from salt.

    Any ideas?

    Wet and dry sand paper, finest you can get, and then whack on some metal polish. You could even just try the metal polish by itself.

        Pretty common problem for VTR250's. Especially those dwelling in close proximity to the ocean. Make sure you wash your bike regularly to best avoid shite like this.

          could try some steel wool - a bit less drastic than sand paper...

              looks like corrosion is coming through the clear coat, only way to fix properly is rub back the whole lot with 400 wet and dry (or sandblast) then graduate to 600 then 1200, then use an aluminium buffing compound and a buffing wheel. metal polish only at the end. Then clear coat again or polish every now and then.

              Easier option is Gozer's suggestion.
              There are two questions in life.
              1:Which way do I go
              2:Whats the lap record.

                Why not use paint stripper on the forks to remove the paint. Then you just need to use Autosol to polish.

                  Thanks for the feedback.

                  I've already tried Autosol metal polish but didnt work.

                  Looks like D.J.'s option is the best. I guess that means I have to remove the forks from the bike first? Or can I just sand off the corroded parts?

                    The forks on my bike (dirty) needed attention, they werent rusty but just looking tatty. Took them off and taped (prefferably duct tape) the delicate parts and sandblasted them. tadaa brand new after re coating

                      Autosol does the trick for me, I usually use a length of rag like a belt to pull back and forth. I suspect that your forks may have a clear coating though.

                        if you want to sandblast/mediablast try bicarb soda, i love the stuff for blasting delicate parts as it is very fine as far as abrasives go, doesn't create a lot of heat and if you have to get it out of bolt holes or parts it dissolves easily in vinegar and can then be rinsed with water, so cleanup is simple compared to sand or beads etc

                          Isn't bicarb very corrosive to aluminium?

                            never thought about it but i wouldn't have thought it would be any more corrosive to aluminium than most metal polishes, it would only be blasting media to be removed once the job is finished.

                            Most metal polishes i've used have an acid or alkali in them to remove the surface corrosion and allow a polished surface to shine through but that same property causes the surface to dull quicker than a surface polished with a pure abrasive and sealed with a wax.

                              I'd like to know how this guy got the cranks cases (not the polished covers) looking like this. I'll bet he's using something like bicarb soda. I tried spray on degreaser and carby cleaner but my bike still has that old grey look.
